Frequently Asked Questions

The loop does outlast the indoor unit, but the heat pump, blower motor, circulation pump, coils, and electrical connections wear on a normal schedule. Skipping service means those components fail without warning. The loop’s longevity is not a reason to skip the indoor side.

Filter changes help, but they leave refrigerant level, loop pressure, glycol concentration, coil fouling, the condensate drain, and electrical connections unchecked. Any one of those can cause a breakdown or efficiency loss that a filter swap would never catch.

Low loop pressure and degraded antifreeze produce no obvious symptoms until the system short-cycles or shuts down mid-season. A blower motor with early bearing wear fails suddenly. Catching either during a routine visit costs far less than an emergency call in January.

Once a year is the standard expectation. Filters may need checking more often in dusty homes or homes with pets. Denver’s wide seasonal swings make a pre-season visit especially useful before the system switches from heavy heating to heavy cooling load.

A complete visit covers loop pressure, glycol concentration, coil cleaning, condensate drain, blower motor amp draw, thermostat calibration, refrigerant level, circulation pump flow rate, and all electrical connections, not just the air filter.

Clear access to the indoor unit and any mechanical room where the heat pump sits. Note any symptoms you’ve observed, unusual sounds, uneven temperatures, or higher energy use, so the partner can check those areas first.

The most common causes are low loop pressure, a circulation pump fault, a control board issue, or a compressor problem. A technician checks the error code, loop pressure, flow rate, and electrical supply before deciding what needs repair, each cause points to a different fix.

A reset is a reasonable first step, but if the same fault code returns, the root cause is still present. Repeated resets on a low-pressure fault can allow the system to run in a damaged state, which risks compressor wear and higher repair costs later.

Running a geothermal system with a confirmed low-pressure fault can cause the compressor to short-cycle under stress. In a Denver winter, that means the house loses heat faster than the system can recover it, and compressor damage can turn a straightforward loop repair into a much larger job.

The technician reviews stored error codes, tests loop pressure and water flow rate against the manufacturer’s spec, checks refrigerant pressure, measures compressor amperage draw, and tests electrical supply voltage. The goal is to isolate whether the fault is in the loop, the indoor unit, or the controls.

Yes. Most Denver-area geothermal systems are installed in basement mechanical rooms, which gives a technician direct access to the indoor unit, circulation pump, and loop connections without needing to work in a crawl space or attic.

If the indoor unit fails repeatedly or can no longer keep the home comfortable, replacement is usually the better path. The decision starts with a loop pressure test and a check of the indoor components, compressor, heat exchanger, circulating pump, to identify exactly where the failure is.

Often yes. If the loop passes a pressure test and the flow rate is within the manufacturer’s range, the buried high-density polyethylene pipe can support a new indoor unit. Reusing the loop avoids excavation and keeps the project significantly smaller.

A unit with a slow refrigerant leak or a failing compressor will short-cycle, raising energy use and putting extra strain on the circulating pump. Delaying through a Denver winter risks a full heating failure when outdoor temperatures are at their lowest.

The federal residential geothermal tax credit does not apply to systems placed in service after the end of 2025. Colorado utility rebate programs may still apply to qualifying replacement equipment, the installer checks current programs before the estimate is issued.

In most cases yes, but a sizing check at replacement time confirms the new unit’s airflow requirements match the existing duct layout. If the ductwork is undersized for the new unit’s output, that is flagged in the written estimate before work begins.

The installer runs an altitude-adjusted load calculation based on the home’s square footage, insulation, and window area. Denver’s elevation affects heating capacity, so matching the nameplate of the old unit is not a reliable method.

Running a failing furnace or AC through another Denver heating or cooling season adds repair costs and risks a full breakdown mid-season. The consultation takes one visit and produces a written scope, so you have the information needed to decide before the current system forces the decision for you.

A written estimate itemising loop type, estimated borehole or trench count, indoor equipment, installation scope, permitting requirements, and timeline. You leave with a specific scope, not a ballpark range.

Operating costs typically drop compared with older equipment, but the result depends on home size, insulation, system design, and site conditions. The consultation explains whether the projected savings are likely to justify the project for your specific property.

The loop field is segmented and each run is pressurized individually to isolate the failing section. Tracer gas or dye is then introduced into that segment to surface at the exact fault point. Targeted potholing exposes only that area, keeping the rest of the yard untouched.

No. A damaged section can often be spliced or replaced if the rest of the loop is still sound. Full replacement is considered only when multiple sections are failing or the pipe condition is too degraded to repair reliably.

Continued fluid loss lowers heat exchange efficiency, causes the system to short-cycle, and raises heating and cooling costs. Glycol dilution from repeated refills can also drop freeze protection below Colorado winter requirements, risking pipe damage.

Sealants are not a confirmed repair for an active loop leak. Pressure loss typically returns, and the loop still needs a proper splice or section replacement. A pressure hold test after any repair is the only way to confirm the fix held.

Many repairs use targeted potholing to reach only the problem area, which is far less disruptive than opening the full loop field. The actual excavation footprint depends on the leak location, burial depth, and whether the pipe runs under hardscape.

The loop is pressure tested to confirm it holds at spec, then flushed and refilled with glycol at the correct antifreeze concentration for Colorado temperatures. A post-repair system check confirms stable heat exchange before normal circulation resumes.

Trenches are typically dug 4 to 6 feet deep. That depth keeps the pipe below Colorado’s frost line and in soil with a stable year-round temperature, which is what drives heat exchange efficiency. The exact depth is confirmed during the site assessment based on local soil conditions and the trench layout design.

The loop field needs enough open, unobstructed yard for parallel trench runs. A typical single-family home requires several hundred to over a thousand linear feet of pipe, spread across multiple trenches. The sizing calculation done at assessment confirms whether your lot can accommodate the required layout.

An undersized loop field forces the heat pump to work harder than its design load, which raises energy use and shortens equipment life. Skipping the load calculation is the most common cause of underperforming systems. The written estimate is only issued after the sizing calculation is complete.

Yes. Backfill is compacted in lifts to reduce settling, and the surface is graded and seeded or sodded as part of the installation scope. Most yards show little visible trace of the trench within one growing season, though some settling in the first year is normal.

Colorado homeowners may claim the 30% federal residential clean energy tax credit on qualifying heat pump loop installations through 2032. Consult a tax advisor to confirm eligibility for your specific project, as credit rules can change and depend on how the system is classified.

The assembled loop is pressurized and held at test pressure before backfill begins. If pressure holds steady, the loop is leak-free. If it drops, the leak is located and repaired above ground, far less costly than finding a fault after the trench is filled.

No. The work covers unit placement, ductwork tie-in, refrigerant line routing and pressure testing, PVC condensate drain installation, thermostat wiring, and a startup test that measures supply air temperature and airflow balance. Each step has to be done in sequence and to spec.

Yes. Denver requires a mechanical permit for indoor HVAC equipment installation. The permit is pulled before work begins, not after. Colorado mechanical code also governs refrigerant handling, which requires certified technicians for sealed system work.

A unit that short-cycles or runs with low refrigerant charge puts extra load on the blower motor and compressor. Continued operation in that state can damage components that are otherwise still serviceable, turning a straightforward indoor unit replacement into a larger repair.

No. A geothermal indoor unit is designed to exchange heat with ground-loop fluid, not outdoor air. The refrigerant circuit, operating pressures, and control logic are specific to that system design. Installing a standard air-source unit in its place will not work with the existing ground loop.

Weak airflow, uneven room temperatures, loud operation, or frequent short-cycling all point to the indoor unit. If the ground-side components are still serviceable, the site evaluation will identify whether the indoor unit is the source and whether replacement is the right next step.

A component-level test answers that. If the compressor holds pressure differential and the refrigerant charge is within tolerance, the fault is usually a single part, reversing valve, expansion valve, or pump, not the whole unit. The written estimate will specify which.

A bypassing reversing valve forces the compressor to work against back-pressure in the refrigerant circuit. Running in that condition accelerates compressor wear, and a compressor replacement costs significantly more than a reversing valve repair.

Yes. EPA Section 608 certification is required to handle refrigerants in any closed refrigerant circuit, including geothermal indoor units. Our partners hold the required certification before any refrigerant circuit work is performed.

Yes. Gradual efficiency loss usually points to a measurable fault: low refrigerant charge, a partially stuck expansion valve, or a pump delivering below its rated flow rate. Each of those is a targeted repair, and leaving them unchecked raises operating costs every billing cycle.

Most single-component repairs, reversing valve, expansion valve, or circulation pump, are completed in one visit once the part is confirmed. Compressor replacements may require a second visit if the part needs to be ordered, but the commissioning check always happens before the job is closed.

Warranty terms depend on the specific part and the partner carrying out the work. The written estimate will state the warranty coverage for both parts and labor before you authorise the repair.

The main factors are groundwater supply, water quality, and whether the site can handle the intake and discharge setup. A water flow test and site review confirm whether the well meets the minimum sustained flow rate and whether a compliant discharge point exists on the lot.

Without a flow test and water quality check, there is no way to confirm the well can sustain the required gallons per minute. Ordering equipment before that check risks specifying the wrong unit size or discovering a disqualifying condition after costs are already committed.

Iron, calcium, and manganese are common in Front Range aquifer water and cause scale buildup inside the heat exchanger. Depending on the water chemistry results, a sediment filter, softener, or sacrificial anode is added to the installation scope to protect the equipment.

Yes. Colorado groundwater discharge regulations vary by county and govern how return water can be released. The site review confirms a compliant discharge point, return well, dry well, or surface outlet, before any equipment is specified.

Not always. Open loop systems depend on water quality and flow rate, so they can need more attention than a sealed loop system if the water carries minerals or sediment. Maintenance needs should be compared against closed loop before a final decision is made.

The HDPE coils need to sit at least 8 feet below the surface at the placement depth to stay below Colorado’s ice formation zone. Shallower placement risks efficiency loss and partial freezing during hard winters. Depth is confirmed during the site assessment, not assumed.

A correctly designed loop placed at the right depth stays below the ice formation zone. The antifreeze solution circulating through the HDPE pipe also provides freeze protection. Shallow or undersized loops are the main freeze risk, both are screened out during the qualification assessment.

Shallow water, low volume, poor water chemistry, a long trench distance from the house, or limited shoreline access can each make the setup impractical. If the water body does not qualify, the assessment will identify which factor is the barrier and what alternative loop type may suit the site.

Skipping or delaying the assessment and installing based on a visual guess can result in an undersized loop that overcools the pond mid-winter, forcing the heat pump to short-cycle and raising operating costs. Correcting a mis-sized submerged loop after backfill means excavating the trench and pulling the coils, a significant added expense.

It can be lower cost when a suitable water body is close to the house, because the loop field itself requires no yard trenching or drilling. Total cost still depends on trench length, loop size, and site conditions. A written estimate after the site assessment gives you the actual number for your property.

A site evaluation checks drill rig access against your side yard width, overhead clearances, and any shared driveway constraints. Front Range ground conditions, soft overburden near the surface, harder bedrock at depth, are also assessed to estimate borehole depth before any scope is written.

Delaying means continuing to run an existing system at its current operating cost. If the existing system fails before a replacement is in place, you lose the option to plan the installation on your schedule, emergency replacements rarely allow time for proper site evaluation and depth sizing.

Depth typically ranges from 150 to 400 feet per borehole, depending on the home’s load calculation and the ground’s thermal conductivity at your specific site. Front Range bedrock conditions can affect drilling time at greater depths, which is why depth is estimated during the site evaluation.

After all boreholes are grouted and headers are connected, the full loop field is pressurised and held at a specified pressure to confirm there are no leaks. A loop with an undetected leak will lose circulating fluid volume over time, reducing heat transfer and raising operating costs.

Yes. Dirty coils, low refrigerant, and a weak circulation pump each reduce the system’s coefficient of performance, meaning it uses more electricity to move the same amount of heat. Annual servicing restores those components to spec, which keeps your energy bills from creeping up year over year.

Minor symptoms rarely stay minor. A small refrigerant leak stresses the compressor; low loop pressure reduces heat transfer efficiency; a loose electrical connection can cause control board damage. Waiting turns a straightforward service call into a more involved repair, often at a higher cost and at an inconvenient time.

Compressor failure is the most serious and costly issue. It is usually preceded by warning signs, low refrigerant, restricted airflow, or a struggling circulation pump, that a maintenance visit would catch. Addressing those precursors is far less expensive than replacing a compressor or the entire indoor unit.

Common signs include rising energy bills without a change in usage, uneven heating or cooling, unusual noises from the indoor unit, or the system running longer cycles than usual. Any of those points to a component working harder than it should. A system that has gone more than a year without service is also overdue regardless of symptoms.

Often yes. Noise commonly comes from a loose panel, worn fan bearings, or a struggling circulation pump, all addressable during a service visit. Weak output usually traces to low refrigerant, dirty coils, or restricted airflow. Correcting those restores normal operation in most cases, though a severely worn compressor may need separate repair.

The most common causes are a refrigerant leak, a failed compressor, or a ground loop that has lost flow or pressure. A faulty reversing valve can also lock the system in cooling mode. A technician will check loop pressure, refrigerant charge, and compressor operation to pinpoint the fault before any repair work begins.

A low pressure fault usually points to a refrigerant leak, a blocked filter, or reduced flow in the ground loop. Do not ignore it, running the compressor under low pressure can cause permanent damage within hours. Shut the system down and call for a diagnostic visit so the source of the pressure drop can be confirmed and fixed.

Repeated tripping is usually caused by high-pressure lockout, overheating, or an electrical fault in the controls or compressor circuit. Low loop flow can also trigger safety shutoffs. Each of these needs a hands-on diagnostic check, the fault code stored in the controller is the first place a technician will look.

Grinding or rattling usually points to a worn circulation pump bearing or loose fan components. Gurgling sounds often mean air or low refrigerant in the loop. A clicking noise at startup can indicate a failing contactor. Each sound pattern points to a different component, so a technician will isolate the source before recommending a fix.

Short cycling, where the unit starts and stops every few minutes, is most often caused by an oversized system, a refrigerant charge issue, or a faulty thermostat or control board. Low loop flow can also trigger rapid cycling. Left unchecked, it accelerates compressor wear significantly, so it is worth diagnosing promptly.

Yes, both are real causes of loop problems in the Denver area. Freeze-thaw movement in clay-heavy soils can shift pipe joints and cause slow leaks that reduce loop pressure over time. If your system loses pressure seasonally or after a hard freeze, a loop pressure test will confirm whether soil movement is the source.

A pressure test checks for leaks and a flow test confirms the loop is circulating at the correct rate. Thermal performance data from the old unit’s run history can also flag a degraded loop. These checks are part of the system evaluation that precedes any replacement quote. More on loop condition.

Geothermal systems typically reduce heating and cooling energy use significantly, but savings show up on your bills after installation, not during the consultation phase. The consultation sizes the system to your actual load, which is the step that determines how much reduction you can realistically expect.

No. Ground loop pressure does not self-correct. Waiting allows the fluid level to drop further, which starves the heat pump of flow and can trigger compressor damage, a far more expensive repair than fixing the loop. A slow pressure drop that continues over days is a clear sign to act now.

A leak shows up as a steady drop in loop pressure over days or weeks, often alongside reduced heating or cooling output. If pressure is stable but performance is poor, the issue is more likely a flow restriction, air lock, or a problem with the indoor unit. A system evaluation can separate the two.

The most common signs are a gradual drop in loop pressure on the system gauge, the heat pump running longer cycles without reaching setpoint, and the fluid reservoir needing repeated top-ups. Wet or unusually soft ground directly above the loop field can also indicate a slow underground leak.

Yes. Low fluid volume reduces flow through the ground loop, cutting the amount of heat the system can extract or reject. The heat pump works harder, efficiency drops, and in severe cases the unit shuts down on a low-pressure fault to protect the compressor. Restoring correct fluid level resolves this directly.

Yes. Denver’s Front Range mix of clay-heavy soils and sedimentary bedrock can shift seasonally, stressing pipe joints over time. Clay soil also holds moisture that accelerates corrosion on any metallic fittings. Partners factor local soil conditions into the repair method and fitting selection to reduce the chance of the same fault recurring.

Upfront installation cost is higher than a conventional furnace or heat pump. Horizontal systems also require substantial yard space and cause temporary surface disruption. In rare cases, soil conditions or lot constraints rule out horizontal loops entirely. Operating costs are lower over time, but the payback period depends on local energy rates and system sizing.

Key signs are rising energy bills without a change in usage, uneven temperatures across rooms, refrigerant leaks, or a compressor that cycles on and off constantly. Units older than 15-20 years with repeated component failures are usually past the point where repair makes financial sense. A system evaluation comparing repair cost against remaining service life gives you a clear answer.

Uneven conditioning usually points to a blower motor losing capacity, a clogged air coil, or a refrigerant charge that has drifted out of spec. Duct leaks between the air handler and the living space can also cause hot or cold spots. A technician can measure airflow and refrigerant pressures to pinpoint which component is responsible.

Frequent service calls usually mean one of two things: a single failing component that keeps stressing other parts, or a unit that is simply worn out and past its design life. Altitude in the Denver area can also accelerate wear on compressors that were not sized with that in mind. Tracking which parts have failed helps determine whether repair or replacement is the better path. See what a full repair assessment covers

Yes. Circulating pumps, flow center controls, expansion valves, and desuperheaters are common fault points that mimic ground loop symptoms. Diagnosing at the mechanical component level first avoids unnecessary ground work. Our partners carry out mechanical component checks as part of the diagnostic process, see mechanical component repair for more detail.

Iron and manganese deposit as scale inside the heat exchanger, reducing heat transfer efficiency and eventually blocking flow. Sediment wears pump impellers and clogs strainers. Hard water causes calcium buildup that narrows internal passages over time. Left unaddressed, these issues force early heat exchanger replacement and raise operating costs well before the system’s expected service life ends.

No, when installed correctly. The loop runs a water-antifreeze mixture calibrated to stay liquid well below the coldest ground and water temperatures Denver sees. The pipe is also sunk below the depth where ice forms in winter. Proper antifreeze concentration is confirmed before the system is commissioned.

An undersized water body cannot absorb or release enough heat, which forces the heat pump to work harder and raises operating costs. If the site evaluation shows the water body falls short, a horizontal loop installation or vertical drilled system may be a better fit for your property.

An itemised written estimate covers equipment (heat pump unit and loop materials), installation scope (drilling or trenching, pipe connections, indoor unit placement), permit fees, and a projected timeline. It also includes the post-install performance check. You receive this after the system evaluation, so the numbers reflect your actual home and site conditions.

The main cost drivers are loop type (vertical drilling costs more than horizontal trenching), total loop footage required, soil or rock conditions, and the size of the indoor heat pump unit. Homes needing ductwork upgrades or electrical panel work add to the total. Most installations in this region run $0-$250 before incentives.

Geothermal systems consistently add to appraised home value, so you recover a portion of the investment at sale even if you leave before the utility savings fully pay back the cost. The federal clean energy tax credit also reduces your net outlay in the year of installation. Whether the math works for your timeline is worth reviewing with your installer.

Most repairs come in at $150-$400, depending on which component has failed and whether the fault is in the indoor unit or the ground loop. Control board and pump replacements sit at the lower end; compressor work or loop repairs cost more. You will receive an itemised written estimate before any work is approved.

The main cost drivers are the failed component, access difficulty, and whether refrigerant recovery and recharge is needed. Ground loop faults cost more than indoor unit repairs because excavation or pressure testing adds time. A straightforward control board or pump swap is at the lower end; compressor replacement or loop leak repair sits at the higher end.

Every job starts with a system evaluation that covers load, equipment condition, and fault diagnosis. The findings are presented in an itemised written estimate before any repair work begins, so you know exactly what the diagnosis found and what the fix will cost before you commit.

Most replacements come in at $4,500-$11,000, depending on unit capacity, loop condition, and whether ductwork modifications are needed. An itemised written estimate covering equipment, installation scope, and timeline is provided before any work begins.

Yes, loop issues found during the evaluation can add cost. A leak, flow restriction, or failed grout seal requires repair before the new unit can operate correctly. The upfront system evaluation is designed to catch these problems early so the written estimate reflects the full scope, not just the indoor unit swap.

A complete quote should itemise the indoor unit, any loop work, ductwork modifications, permits, commissioning, and the post-install performance check. Labor and equipment should be listed separately so you can see what each element costs. Vague lump-sum quotes make it hard to compare proposals or understand what is and is not covered.

The written estimate covers the full scope identified during the system evaluation, including equipment, installation, and any loop or ductwork work required. If the loop is in good shape and only the indoor unit needs replacing, the estimate reflects that narrower scope. Nothing is assumed to be included unless it is listed.

Consultation pricing in the Denver area runs $0-$250, depending on property size and the detail of load analysis required. The cost covers the site visit, altitude-adjusted sizing, and a full itemised written estimate.

The main factors are property size, system complexity, and how much existing equipment needs to be evaluated. Larger homes with multiple zones or older ductwork require more detailed load analysis, which adds time and affects the overall planning cost.

Most horizontal loop installations in the Denver area come in at $12,000-$18,000, depending on loop length, soil conditions, and system size. An itemised written estimate covering equipment, installation scope, and timeline is provided before any work begins, so there are no surprises.

Yes, trenching and backfilling are part of the installation scope. The itemised written estimate you receive before work starts breaks out equipment, excavation, pipe, and backfill so you can see exactly what is covered and what each element costs.

Rocky or heavily compacted soil can slow excavation and add machine time. Unmarked utilities, irrigation lines, or buried debris discovered during digging may require rerouting. The pre-install site evaluation is designed to flag these conditions early so they appear in the estimate rather than as change orders mid-job.

Most installations come in at $3,500-$6,500, depending on unit capacity, access conditions, and whether ductwork or electrical work is needed. Every enquiry includes an itemised written estimate covering equipment, installation scope, and timeline before any commitment is made.

The main cost drivers are unit capacity, difficult access to the mechanical space, ductwork modifications, electrical panel upgrades, and altitude-adjusted equipment selection. Older homes with non-standard layouts or undersized electrical service tend to carry higher installation costs than newer builds with dedicated mechanical rooms.

Occasionally, yes. Corroded water connections, deteriorated duct collars, or undersized wiring are not always visible before the old unit is removed. When that happens, our partners document the finding and provide a revised scope before proceeding. Nothing is added to the job without your approval.

Geothermal installation runs higher upfront than a standard HVAC replacement because it includes ground loop excavation or drilling in addition to the indoor unit. Federal tax credits currently offset 30% of the installed cost, which narrows that gap significantly. Operating costs are typically lower year-round, so the payback period matters as much as the initial price.

The written estimate is itemised and covers equipment, the full installation scope, and the project timeline. It is produced after the system evaluation, so the figures reflect your actual load calculation and site conditions rather than a generic estimate. Nothing is bundled in a way that obscures individual line items.

Yes. The itemised estimate covers equipment, installation scope, and timeline, and every install includes a post-install check to confirm the system performs as specified. Loop work, the indoor unit, and commissioning are all accounted for in the written quote you receive before any work begins.

The main drivers are loop type and depth, system tonnage based on your load calculation, soil conditions, and site access for drilling or trenching equipment. Altitude-adjusted sizing at Denver’s elevation also affects equipment selection. A quote built on a proper load calculation will reflect your actual requirements rather than a rough estimate.

Most open loop installs require a submersible well pump sized for continuous geothermal flow, a sediment strainer before the heat exchanger, and sometimes an iron filter or water softener if mineral levels are elevated. Properties using a return well need a second pump to push discharge water back down. Each add-on is itemised in the written estimate before work begins.

Drilling a new supply or return well is the largest variable cost. Rocky substrate or deep aquifer depth increases drilling time and casing material. Water quality problems that require filtration equipment add to the upfront cost. Long pipe runs between the well and the mechanical room, or difficult trench access, also push the total higher. Most jobs come in at $14,000-$20,000, depending on these site factors.

The main factors are the distance from the water to the home, the depth and difficulty of the trench run, the loop size required for your heating and cooling load, and any shoreline or access challenges. Most pond lake loop installations come in at $15,000-$22,000, with the final figure set in an itemised written estimate after the site evaluation.

Yes, unexpected obstacles, buried utilities, rock, or poor soil, can add labor and materials beyond the original estimate. The site evaluation is designed to surface these issues before work starts, and the written estimate covers the full installation scope. Any scope change is discussed with you before additional work proceeds.

Yes. A pond loop quote requires a site evaluation covering the water body’s depth and volume, the trench route, your home’s heating and cooling load, and existing equipment condition. Without that, any figure would be a guess. The evaluation produces an itemised written estimate with equipment, installation scope, and timeline.

Borehole depth, number of loops, soil and rock hardness, site access difficulty, and the distance from boreholes to the mechanical room all affect the final figure. Most vertical loop installations in this region come in at $20,000-$30,000. The itemised written estimate breaks down each cost driver before any work begins.

Hard rock or unexpected cobble layers slow drilling and increase bit wear, which can add to the cost. The site evaluation reviews available geological data for your area to flag this risk upfront. Where hard formation is likely, the written estimate accounts for it rather than leaving it as a change order after drilling starts.

A system evaluation covering your home’s heat load, existing equipment condition, and lot characteristics determines fit. Most homes qualify, but the ground loop design depends on your available land, soil type, and how much heating and cooling your home requires. A geothermal system consultation gives you a clear answer before any commitment.

Yes, older homes can use geothermal, though they sometimes need ductwork sealing, electrical panel upgrades, or insulation improvements first. The heat pump unit itself installs in place of your existing furnace and air handler. An evaluation of your current equipment and load tells you exactly what prep work, if any, is needed.

Yes. A properly sized geothermal system handles both full heating and full cooling for the entire home. Sizing is based on a load calculation that accounts for your square footage, insulation levels, window area, and local climate. At Denver’s altitude, that calculation is adjusted to reflect actual heating and cooling demand.

Horizontal loops typically need roughly 1.5 to 2 times your home’s square footage in open yard area. If your lot is smaller or heavily landscaped, vertical drilling uses a much smaller footprint. Your installer will assess your lot and recommend the loop type that fits. Horizontal loop installation and vertical loop installation are both available.

Yes. Vertical drilling requires only a small drill rig footprint, leaving most of your yard undisturbed. Boreholes are typically 4 to 6 inches in diameter and drilled straight down, so surface disruption is limited to the drill pad area. Once grouted and capped, the yard surface is largely restored.

In most cases, yes. Geothermal heat pumps connect to standard forced-air duct systems. Older or leaky ductwork may reduce efficiency, so the evaluation checks duct condition alongside the load calculation. Sealing or minor duct repairs are sometimes recommended before installation to get full performance from the system.

Yes. Water-to-water geothermal heat pumps are designed specifically for hydronic systems, including radiant floor heating and baseboard radiators. The heat pump replaces your boiler and delivers heated water at the temperatures your system needs. Your installer will confirm the required supply temperature during the system evaluation.

Geothermal works in most soil and rock types, but thermal conductivity affects loop length. Dense, moist soil or solid rock transfers heat well and needs less loop footage. Dry sandy soil or expansive clay is less efficient and may require a longer loop or vertical drilling. Your installer accounts for local ground conditions in the loop design.

Many Denver lots are compact enough that vertical drilling is the practical choice. Horizontal loops need roughly 1.5 to 2 times your home’s conditioned square footage in open yard area. A site evaluation measures your usable lot space and recommends the loop type that fits without sacrificing landscaping you want to keep.

Yes. Expansive clay has lower thermal conductivity than denser soils, which typically means more loop footage to meet the same load. Shallow bedrock can actually improve heat transfer but may require specialized drilling equipment. Both conditions are assessed during the site evaluation and factored into the loop design and footage specified in your estimate.

Yes. The ground loop is durable, but the indoor heat pump unit has compressors, pumps, coils, and electrical components that wear over time. Annual service keeps those parts running efficiently and catches issues before they cause a breakdown, regardless of how long the loop itself is rated to last.

Yes, and that timing is recommended. Servicing in early fall before heating season, or in early spring before cooling season, means any issues are resolved before the system runs at peak load. Scheduling ahead also avoids the busy-season backlog when more homeowners are calling for urgent repairs.

It covers both. The indoor heat pump unit gets the full mechanical and electrical check, while the ground loop side is assessed through pressure testing and, where applicable, antifreeze concentration measurement. If loop pressure is off, that finding is documented and a ground loop inspection can be arranged.

Denver’s low humidity reduces some moisture-related issues like coil corrosion, but the altitude and wide temperature swings, from sub-zero winters to 90-degree summers, put real demand on the compressor and loop system. Annual service remains the right interval; the seasonal extremes make skipping a year a higher risk here than in milder climates.

Check the thermostat mode, setpoint, and schedule first, a system accidentally left in cooling mode or with a low setpoint will underperform without any fault present. Also confirm the circuit breaker is on and the loop pump switch is enabled. If the settings look correct and performance is still poor, the problem is mechanical or refrigerant-related and needs a technician.

Yes, our partners handle faults in the indoor heat pump unit, the ground loop, and the controls that connect them. Indoor repairs cover compressors, refrigerant circuits, pumps, and control boards. Ground loop work covers pressure loss, leaks, and flow issues. Ground loop repair details

Yes, in most cases. A loop leak can be located and sealed, and a section of damaged pipe can be replaced without disturbing the rest of the loop. Full loop replacement is only necessary when the pipe has widespread damage or has degraded beyond repair. A pressure test will confirm the extent of the problem first.

Yes. Circulation pump failures and control board faults are among the most straightforward geothermal repairs. Pumps are replaced as a unit, and most control boards are available as direct replacements. Mechanical component repair covers both, and the system is tested for correct operation before the visit closes.

Yes. Geothermal systems combine pressurised ground loops, refrigerant circuits, and variable-speed controls that standard HVAC technicians rarely work on. Refrigerant handling requires EPA Section 608 certification, and loop pressure work requires knowledge of closed-loop hydraulics. A technician without geothermal experience can misdiagnose faults or cause additional damage.

Yes, in most cases the ground loop can stay in place. The loop is the most expensive part of any geothermal system, and it typically outlasts two or three indoor units. A pressure and flow test confirms whether the loop is still performing to spec before the new unit is connected. Learn more about ground loop condition checks.

Sizing is confirmed through a load calculation that accounts for your home’s square footage, insulation, and Denver’s altitude. If the existing ductwork is undersized or leaking, that gets flagged in the evaluation. A correctly sized unit on a mismatched duct system will underperform, so both are assessed together.

The main drawbacks are higher upfront cost and the need for yard or drilling access during initial installation. Once installed, operating costs are low and the ground loop rarely needs attention. For replacements where the loop already exists, the cost and disruption are significantly lower than a full new installation.

Yes, provided the loop passes a pressure and flow test. Modern geothermal units are compatible with standard closed-loop configurations. The evaluation checks loop capacity against the new unit’s requirements, so any mismatch is caught before installation rather than discovered after the unit is running.

Yes. Older homes often have existing geothermal systems that simply need the indoor unit updated. The main considerations are duct condition, electrical panel capacity, and whether the loop was sized for the original load. The evaluation checks all three and flags any upgrades needed before the new unit is specified.

A site evaluation is the only reliable way to know. A consultant reviews your lot size, soil conditions, existing equipment, and heating and cooling load to determine whether a ground loop system is viable. Most Denver-area properties can accommodate some form of geothermal, but the right loop type varies by site.

No, but the amount of space you have determines which loop type works. Horizontal loops need more surface area, while vertical loops go straight down and fit on smaller lots. A site assessment measures your available land and recommends the configuration that matches it.

No, geothermal can be retrofitted into existing homes. The consultation checks your current ductwork, equipment condition, and load requirements to confirm compatibility. Many Denver-area homeowners have added geothermal to older properties without a full rebuild.

It depends on your existing equipment and duct configuration. The consultation includes an evaluation of your current system’s condition and compatibility with a geothermal heat pump. If modifications are needed, they are itemised in the written estimate before any work begins.

Yes, a small lot typically points toward a vertical loop system, which requires only a few bore holes rather than wide trenches. The consultation measures your lot and confirms whether vertical drilling is feasible given soil depth and any buried utilities.

That depends on your lot size, soil type, and local bedrock depth. Horizontal loops suit larger yards; vertical loops work where space is limited; pond or lake loops apply if you have a water body nearby. A site assessment determines which configuration fits your specific property. See horizontal loop installation or vertical loop installation for more detail on each approach.

Trees and buried utilities affect loop placement but rarely rule out geothermal entirely. The site assessment maps obstacles and adjusts the loop layout or type accordingly. If a specific area is off-limits, the consultant identifies an alternative configuration that avoids it.

Yes. The consultation produces a written estimate with full scope and cost detail, which gives you concrete numbers to compare against other heating and cooling options. There is no obligation to proceed, so it is a low-risk way to get accurate information.

Yes. Arvada lots in Jefferson County vary widely in size and soil composition, and a site assessment determines which loop type fits your specific parcel. The consultant measures available land, checks for buried utilities, and reviews soil depth before making a recommendation. See Arvada, Jefferson County for area-specific information.

No. Ground loop repair requires pressure testing equipment, tracer gas detection, and the ability to fuse or mechanically join HDPE pipe to a pressure-rated standard. An improper repair that fails underground can damage the heat pump and void any existing equipment warranty. This work needs a geothermal-trained installer.

Yes, and acting while the system still runs is the best time. A slow pressure loss that is caught early usually means a small, accessible repair. Waiting until the system faults out risks compressor damage and a much larger repair bill. A running system also makes pressure testing easier to perform accurately.

A typical residential horizontal loop requires roughly 1,500 to 3,000 square feet of open yard per ton of heating and cooling capacity. A 3-ton system for an average home therefore needs somewhere between 4,500 and 9,000 square feet of usable ground. Obstacles like trees, driveways, and setbacks reduce what counts as usable.

It depends on your lot size and soil type. Horizontal loops suit properties with enough open, unobstructed yard to run trenches at the required depth. A load calculation and site evaluation confirm whether your lot can accommodate the loop length your home’s heating and cooling demand requires.

Possibly not. If usable open yard falls short of the loop length your system needs, a vertical loop or open-loop configuration may be a better match. A load calculation and site walkthrough will give you a clear answer before any commitment is made.

That is confirmed during the pre-install evaluation, which includes a heating and cooling load calculation, a review of your lot dimensions, and an assessment of obstacles like trees and utilities. The written estimate that follows maps out the loop configuration sized to your home’s actual demand.

If the site evaluation finds that soil conductivity is too low or the lot is too constrained for a horizontal layout, vertical wells or an open-loop system may be recommended instead. No installation is proposed until the site conditions confirm a viable path forward.

A 2,000 sq ft home in Denver typically needs a 3- to 4-ton system, which requires roughly 6,000 to 12,000 square feet of open yard for a horizontal loop. If your lot has that usable space clear of trees, structures, and setbacks, a horizontal loop is a viable option worth evaluating.

Yes, larger suburban lots in the Denver metro area are often well-suited for horizontal loops. Flat or gently sloped yards with clay-loam or sandy soil and minimal tree coverage give excavation crews room to work efficiently. A site evaluation confirms usable area after accounting for setbacks, utilities, and existing landscaping.

It depends on whether the new unit’s flow rate, entering water temperature range, and refrigerant type match what your ground loop delivers. Before any equipment is ordered, our partners run a full system evaluation covering load, existing equipment condition, and altitude-adjusted sizing to confirm compatibility. Mismatched equipment is the most common cause of poor geothermal performance.

Correct sizing depends on your home’s square footage, insulation levels, window area, and Denver’s altitude, which affects heat pump capacity. Every project starts with a load calculation before equipment is selected. An oversized unit short-cycles and wears out faster; an undersized one runs constantly and never reaches setpoint.

Yes, layout can add complexity. Tight mechanical rooms, long refrigerant line runs, or ductwork that was not designed for a geothermal air handler all increase labor time. The system evaluation and itemised written estimate spell out exactly what your layout requires before work begins, so there are no surprises on installation day.

Compatibility hinges on loop flow rate, water temperature range, and the new unit’s operating specs. Our partners evaluate the existing ground loop and all connected equipment as part of the initial system assessment. If the loop or ancillary components are undersized or degraded, that gets flagged in the written estimate before installation starts. Learn more about ground loop condition

Often yes, but older homes sometimes have mechanical spaces that were not designed for modern equipment footprints. The system evaluation checks clearances, duct configuration, and electrical service before equipment is selected, so any required modifications are known upfront rather than discovered mid-installation.

Every enquiry starts with a full system evaluation covering your home’s heating and cooling load, existing equipment condition, and altitude-adjusted sizing, so suitability is confirmed before any work is quoted. Soil type, lot size, and access for drilling or trenching are all assessed at that stage. You get a clear answer before committing to anything.

Geothermal works in older homes, but the fit depends on insulation levels, existing ductwork condition, and the home’s heat load. A load calculation done during the initial evaluation flags any upgrades needed before sizing the system. Older homes in Denver’s climate often see the biggest efficiency gains once those factors are addressed.

It depends on your existing duct condition and sizing. Geothermal heat pumps move larger air volumes at lower temperatures than a gas furnace, so undersized or leaky ducts can reduce performance. The initial evaluation checks existing equipment condition, which includes ductwork, and the written estimate will flag any changes needed.

Horizontal loops typically need roughly 400 to 600 linear feet of trench per ton of capacity, so a 3-ton system may require 1,200 to 1,800 feet of trench space. The site evaluation maps your usable yard area against the calculated load to confirm whether horizontal loops are viable. If space is tight, vertical boreholes are assessed as an alternative.

Vertical boreholes are used when the lot is too small for horizontal trenches, when soil conditions favor drilling, or when surface disruption needs to be minimized. The site evaluation determines which loop type suits your property. You can also review the vertical loop installation page for more detail on that approach.

If horizontal trenching is not feasible, vertical boreholes or a pond/lake loop may still work depending on your site. The evaluation covers all loop options against your specific lot. If no ground loop configuration is viable, that finding is communicated clearly so you can weigh other heating and cooling options.

Three factors decide it: adequate groundwater yield, acceptable water quality, and a legal discharge option. A site evaluation tests well output, runs a water analysis, and confirms local permitting allows open loop use. Properties with a productive well and a suitable discharge point, surface water, a return well, or a dry well, are typically good candidates. A consultation can assess all three.

Most residential open loop systems need a sustained well yield of 1.5 to 3 gallons per minute per ton of heating and cooling capacity. A 3-ton system typically requires 5 to 9 gallons per minute continuously. A well flow test, not just a static water level reading, is the only reliable way to confirm your well can sustain that draw without dropping below the pump intake.

Water with high iron, manganese, hardness, or hydrogen sulfide can foul heat exchanger surfaces and shorten equipment life. A lab water analysis before installation identifies problem minerals. Slightly elevated hardness is often manageable with a filter or softener; severely corrosive or heavily mineralized water may make a closed loop system a better fit.

Open loop systems scale to almost any home size, provided the well yield matches the load. Sizing starts with a Manual J heat load calculation adjusted for Denver’s altitude, which determines how many tons of capacity you need and, in turn, how many gallons per minute the well must supply. Undersized well flow is the most common reason a property is ruled out.

Closed loop systems generally require less ongoing attention because the fluid is sealed and never contacts raw groundwater. Open loop systems need periodic strainer cleaning, annual water quality checks, and occasional heat exchanger inspection for scale. If your water is clean and low in minerals, the maintenance burden is modest, but it is higher than a closed loop system by design.

Not always. If your existing domestic well produces enough flow above your household water demand, it can sometimes supply the heat pump as well. More often, a dedicated geothermal supply well is drilled to avoid drawing down the domestic supply. A return well or alternative discharge point is almost always a separate bore from the supply well.

Open loop is one of the more space-efficient geothermal options because it requires only vertical well bores rather than extensive horizontal trenching. The well head and mechanical connections have a small footprint. Properties too small for horizontal loop fields are often good candidates for open loop, provided groundwater and discharge options are available.

High mineral content does not automatically disqualify a property, but it does require mitigation. A water softener handles hardness; an iron filter addresses iron and manganese. If mineral levels are extreme, particularly high sulfur or very aggressive pH, the corrosion risk to copper heat exchanger components may make a closed loop system a more practical choice.

Colorado regulates groundwater use under prior appropriation law, so an open loop system requires a water right or an exemption permit from the Colorado Division of Water Resources. Most single-family residential systems qualify for a household use exemption, but discharge method and volume affect what is permitted. Confirming this before drilling is a standard part of the site evaluation.

No, not every body of water qualifies. The pond or lake needs sufficient depth, surface area, and volume to maintain a stable temperature year-round. Seasonal ponds that dry out or freeze solid to the bottom will not sustain reliable heat exchange. A site evaluation confirms whether your water body meets the thermal requirements before any work begins.

As a general guide, the water should be at least 8 feet deep at its shallowest point and hold enough volume to absorb heat without significant temperature swings. Surface area matters too, a small, shallow pond serving a large home will be undersized. The exact figures depend on your home’s heating and cooling load, which is calculated during the initial system evaluation.

Longer supply and return trenches add pipe, labor, and pumping energy, so distance does affect both cost and efficiency. Most installations stay practical within a few hundred feet of the home. Beyond that, the trench run can offset the savings a pond loop offers over drilling. A site evaluation maps the actual route and flags any distance-related concerns upfront.

It depends on whether a clear, accessible path exists between the water and your mechanical room. Steep banks, rocky shorelines, mature tree roots, or existing underground utilities can all complicate the trench run. A site walkthrough identifies obstacles before the estimate is written, so there are no surprises during installation.

Older homes often have undersized duct systems or no ductwork at all, which limits how effectively a geothermal system can deliver conditioned air. High-infiltration envelopes also increase the heating load beyond what a standard pond loop is sized for. If the existing equipment or structure cannot support the output, the system will underperform regardless of loop quality.

Yes. The water body must hold adequate depth and volume consistently across seasons, not just during spring runoff. A pond that drops significantly in late summer or freezes solid in winter cannot maintain stable heat exchange. If your water access is seasonal or marginal, a vertical or horizontal loop system is the more dependable choice.

Vertical loops suit most properties where land area is limited but drilling depth is accessible. A system evaluation covers your heating and cooling load, lot size, and soil conditions before any work is scoped. Properties with tight yards, existing landscaping, or hard surface coverage are typically the strongest candidates.

Most sites in the Denver area can be drilled, but underground utilities, easements, and bedrock depth all affect feasibility. A site evaluation checks these factors before you commit to anything. If drilling is not viable, alternatives like horizontal or open-loop systems are assessed at the same stage.

Drilling rigs typically need a clear corridor of roughly 10-15 feet wide and overhead clearance free of low branches or power lines. A site walkthrough confirms whether your driveway, side yard, or backyard can accommodate the equipment. Most standard residential lots have at least one viable access point.

Loop depth and borehole count are calculated from your heating and cooling load, local ground temperature, and soil thermal conductivity. The system evaluation includes altitude-adjusted sizing, which matters at Denver’s elevation. That calculation drives the number of boreholes and their spacing to avoid thermal interference between loops.

Shallow bedrock actually favors vertical loops because it provides stable, thermally conductive material at depth, reducing the number of boreholes needed. Dense clay soils have lower thermal conductivity, which may require slightly deeper or additional boreholes. Both conditions are assessed during the site evaluation so the loop design accounts for them.

Geothermal handles both heating and cooling from a single system. In heating mode it extracts heat from the ground; in cooling mode it reverses the process and rejects heat back into the ground. You replace your furnace and central AC with one unit, and it handles both functions year-round.

If your furnace or AC is near end of life, replacing both with a single geothermal system avoids paying twice for separate equipment. Waiting means another conventional system purchase that delivers no long-term efficiency gain. The federal residential clean energy credit is currently available and reduces upfront cost, so delaying has a real financial downside.

Geothermal typically delivers three to five units of heating or cooling energy for every one unit of electricity consumed, compared to roughly one-to-one for a standard furnace or resistance heat. That efficiency gap translates to lower monthly operating costs. The higher upfront cost is the main trade-off, offset in part by federal and state incentives.

Filter changes help airflow but leave refrigerant charge, loop pressure, electrical connections, and coil fouling unchecked. Those hidden issues can quietly cut efficiency or cause a compressor failure. A full inspection catches what a filter swap cannot, so both are needed to keep the system running properly.

Geothermal systems require a specialist. Checking refrigerant charge requires EPA Section 608 certification, and loop pressure testing needs familiarity with closed-loop hydronic systems. A general handyman can swap a filter, but cannot legally or safely handle the refrigerant and loop diagnostics that matter most.

Geothermal systems are more complex than standard HVAC, so service requires a technician familiar with both refrigerant circuits and hydronic loop systems. Parts can also have longer lead times than common furnace components. That said, geothermal systems typically need fewer emergency calls than conventional equipment when maintained on schedule.

Yes. Standard HVAC maintenance does not include loop pressure testing, antifreeze concentration checks, or circulation pump diagnostics, all of which are specific to geothermal systems. The refrigerant side is similar, but the ground loop adds a hydronic component that requires different tools and training to service correctly.

Most faults, refrigerant leaks, failed pumps, faulty controls, worn contactors, are repairable without replacing the whole system. Replacement makes more sense when the compressor has failed on a unit that is already past its expected service life, or when repair costs approach the cost of a new unit. A system evaluation will clarify which path is more cost-effective. See replacement options

One reset is reasonable, power the unit off at the breaker for 30 seconds, then restart. If it trips again or the fault code returns, do not keep resetting it. Repeated resets on a compressor or pressure fault can cause permanent damage. Call for a diagnostic visit if the problem comes back after a single reset.

A reset fixes a one-off control glitch; it does not fix a mechanical or refrigerant fault. If the system runs normally after a reset and the fault does not return within 24 hours, a reset may have been enough. If the same fault code reappears, or performance stays poor, the underlying cause needs a proper diagnosis.

Yes. Indoor unit repairs involve refrigerant, electrical, and mechanical components and are completed without disturbing the ground. Loop repairs require pressure testing, and sometimes excavation, to locate and fix a leak or flow restriction. Loop work generally takes longer and costs more, but the diagnostic process starts the same way for both.

Repair makes sense when the fault is a single component and the unit is under 15 years old. Replacement becomes the better call when the compressor fails on an older unit, efficiency has dropped noticeably, or repair costs approach half the price of a new system. A system evaluation comparing current condition against a new unit’s output helps make that call clearly.

If your ground loop is intact, keeping geothermal is almost always the better choice. Ground-source systems run at higher efficiency than air-source units because ground temperatures stay stable year-round, which matters in Denver’s cold winters. Switching to air-source means abandoning a working loop and accepting lower efficiency. Replacement of just the indoor unit preserves that advantage.

Continued repair makes sense when the unit is under 15 years old and faults are minor. Beyond that point, repair costs accumulate and efficiency stays low. A unit needing its second or third major repair in a few years is typically past the point where repair is cost-effective compared to replacement. See what repair covers.

Replace only the indoor unit when the loop is intact and performing correctly. A full system replacement is warranted when the loop is undersized, damaged beyond repair, or was installed with a configuration that no longer suits the home. The evaluation determines which scenario applies so you are not replacing more than necessary.

If your current system is near end of life or repeatedly failing, repair costs can add up quickly without solving the underlying inefficiency. The consultation evaluates your existing equipment’s condition, so you get a clear comparison between continued repair spending and the cost of switching to geothermal.

Geothermal replaces both a furnace and central AC with one system, which can simplify maintenance and reduce long-term energy costs. Whether it makes financial sense depends on your home’s load, lot configuration, and current equipment age, all of which the consultation assesses directly.

No. Most leaks are isolated to a single joint, fitting, or short pipe section and can be repaired without replacing the full loop. Full replacement is only warranted when multiple failure points exist, the pipe material has degraded throughout, or the loop layout makes targeted access impractical.

No. Chemical sealants are not a permanent fix for buried HDPE or polyethylene loop pipe. They can partially block flow, reduce heat exchange efficiency, and mask a worsening failure. A proper repair means excavating the damaged section and making a fused or mechanical joint rated for continuous underground pressure.

A small, isolated leak is almost always fixed with a section repair. The damaged segment is cut out and replaced with a fused or compression-fitted piece of matching pipe. Full line replacement is only considered when the pipe shows widespread brittleness, multiple leaks, or a diameter mismatch that limits flow.

Repair is the right call when the fault is isolated and the rest of the pipe is in good condition. Replacement makes more sense when the loop is old, shows multiple weak points, or uses a pipe material that is no longer rated for the application. A pressure test and inspection clarify which path fits your situation.

Not necessarily. Recurring pressure loss can mean multiple small leaks, a single leak that was not fully repaired, or a failing fitting at the manifold. A thorough pressure and tracer test maps every fault point. Full replacement is only recommended when the pipe itself is the problem across the whole loop field.

Horizontal loops cost less upfront but need significantly more yard space. Vertical wells require a much smaller surface footprint but involve deeper drilling, which raises equipment costs. If your lot has the open acreage, horizontal is usually the more affordable path. A site evaluation confirms which layout your property can support. Compare vertical loop installation

DIY geothermal kits exist, but horizontal loop installation involves heavy excavation equipment, pressure-tested HDPE pipe fusion, refrigerant handling, and electrical work that require licensed contractors in Colorado. Errors in loop sizing or pipe fusion can cause system failure or void equipment warranties, making the apparent savings short-lived.

You can, and it may make sense if your existing equipment has several years of useful life left. The pre-install evaluation includes a review of your current equipment’s condition, so you get an honest read on whether deferring the project is practical or whether aging equipment will offset the delay’s savings.

Clay soil is actually favorable for horizontal loops because it holds moisture well and transfers heat more efficiently than dry sandy soil. Denver’s Front Range clay-heavy soils generally support good loop performance. Rocky or gravelly subsoil is a bigger concern, which is why a soil assessment is part of the pre-install evaluation.

No. A geothermal indoor unit exchanges heat with water circulating through a ground loop, not with outdoor air. That means it operates at a stable entering water temperature year-round rather than fighting Denver’s cold winters or hot summers. The refrigerant circuit, coil design, and flow controls are all built around water-source operation, not air-source.

There is more involved. The installation includes disconnecting and removing the old unit, making water-side and refrigerant connections, tying into existing ductwork or hydronic distribution, electrical hookup, and a post-install startup check to confirm the system performs as specified. The written estimate covers every element of that scope before work begins.

If the unit is under 12-15 years old and the repair cost is below roughly one-third of replacement cost, keeping it running usually makes sense. Beyond that threshold, ongoing repairs tend to cost more than the efficiency and reliability gains from a new unit. A system evaluation gives you the condition data to make that call with real numbers rather than guesswork.

No. Geothermal indoor units involve refrigerant handling, which requires EPA Section 608 certification, plus water-side connections and electrical work that must meet local code. An incorrect installation can void equipment warranties, damage the ground loop, and create safety hazards. This is not a project suited to unlicensed work.

That depends on your current equipment’s condition, which is assessed during the initial evaluation. Running a failing system through another Denver winter risks a mid-season breakdown when repair costs and emergency rates are highest. If the evaluation shows the existing system has useful life left, that finding is included in the written estimate so you can make an informed decision.

Geothermal makes the most sense when your lot can accommodate a loop, your home’s load justifies the upfront cost, and you plan to stay long enough to reach payback. The system evaluation covers load, site, and existing equipment so the recommendation is grounded in your specific situation rather than a general preference. A geothermal system consultation is the right starting point.

Geothermal installation requires altitude-adjusted load calculations, ground loop design, and drilling or trenching that falls outside standard HVAC scope. A contractor without geothermal experience is likely to undersize or oversize the loop, which directly affects efficiency and longevity. Our partners specialize in geothermal systems, not general HVAC.

Yes. Replacing a ground loop is a major excavation job, so mechanical components are checked first to rule out a simpler cause. Pump failures, valve faults, and control issues are far less expensive to fix than a loop replacement. The diagnostic process is designed to confirm the loop is actually the problem before any ground work is recommended.

No. An open loop system draws real groundwater through the heat pump and discharges it separately. A closed loop circulates a sealed antifreeze solution through buried or submerged pipes, never touching the aquifer. Open loop systems can be more efficient where groundwater temperature is stable, but they depend on water availability and quality that closed loop systems do not.

A standard air-source heat pump loses efficiency when outdoor temperatures drop below about 35 degrees F, which happens regularly in Denver winters. An open loop system draws from groundwater that stays near 50 to 55 degrees F year-round, so efficiency stays consistent regardless of outdoor conditions. The higher upfront cost is typically offset by lower operating costs over the system’s life.

A gas furnace has a lower installation cost but burns fuel for every BTU of heat it produces. An open loop geothermal system moves heat from groundwater rather than generating it, delivering roughly 3 to 5 BTUs of heat per BTU of electricity consumed. It also provides cooling in summer, which a furnace does not. The right choice depends on your fuel costs and how long you plan to stay in the home.

Usually yes, when a suitable water body is close to the home. Drilling vertical boreholes requires specialized rigs and significant labor per foot, which drives up cost. A pond loop avoids that drilling expense, but longer trench runs or difficult shoreline access can narrow the gap. The itemised estimate will show the actual difference for your specific site.

The right choice depends on what your property offers. A pond loop suits sites with a deep, adequately sized water body close to the home. Horizontal trenching works where open land is available. Vertical drilling fits smaller lots or rocky ground where trenching is impractical. A geothermal system consultation maps your site against all three options.

A pond loop can be more cost-effective than trenching when the water body is close and deep enough, because it avoids excavating large areas of your yard. However, if the trench run to the water is long or the shoreline is difficult, horizontal trenching on open land may be simpler and less disruptive. The site evaluation compares both options directly.

A geothermal system moves heat rather than generating it, so it delivers roughly 3-5 units of heating or cooling energy for every 1 unit of electricity consumed. A gas furnace converts fuel to heat at less than 100% efficiency, and a standard AC unit operates at a coefficient of performance well below a ground-source system. The higher upfront cost is offset by lower operating costs over the system’s lifespan.

Vertical loops generally cost more upfront because drilling is more equipment-intensive than trenching. However, on lots where horizontal trenching would require removing mature landscaping or hardscape, vertical drilling can be the lower total-cost option once restoration work is factored in. The right comparison depends on your specific site conditions.

Horizontal loops need roughly 1,500-3,000 sq ft of open trench area per ton of capacity, so they are only practical on larger, unobstructed lots. If your yard cannot accommodate that footprint without major disruption, waiting for horizontal installation does not make sense. A site evaluation confirms which loop type fits your property before you decide. Compare the two options

Yes, for most smaller urban and suburban lots vertical drilling is the practical choice. Horizontal trenching on a compact lot would consume the entire yard and require removing fencing, patios, or mature trees. Vertical boreholes concentrate the ground loop into a small surface footprint, leaving the rest of the lot intact.

Horizontal loops involve trenches roughly 4 to 6 feet deep across a large portion of your yard. Vertical loops require drilling boreholes 150 to 400 feet deep, with a much smaller surface footprint. The scope depends on your lot size, soil conditions, and the system’s heating and cooling load. Your written estimate details the exact loop type and footage.

A geothermal system has two main parts: the ground loop buried outside and the heat pump unit installed indoors. The loop circulates fluid that absorbs or releases heat from the ground. The indoor unit conditions that fluid and distributes heating or cooling through your existing ductwork or hydronic system. A post-install check confirms both parts perform as specified.

No. Every geothermal system requires some ground work, either trenching for horizontal loops or drilling for vertical ones. Vertical drilling minimizes surface disruption significantly, but a drill rig still accesses your yard. The installer restores the disturbed area after loop installation and pipe connections are complete.

Horizontal loop installation disturbs the most surface area, typically requiring trenches across a large section of lawn. Vertical drilling is far less disruptive, affecting only the drill pad and the trench connecting the borehole to your home. Driveways are rarely affected unless the loop path crosses one, which your installer plans around during the site evaluation.

Usually no. Installers route loop piping to avoid hardscaping where possible. If a pipe trench must cross a driveway or sidewalk, the installer bores under it rather than cutting through it. Your written estimate will flag any hardscape crossings and describe how they will be handled.

Most residential installations take between three and five days from ground loop work through indoor unit commissioning. Larger homes, complex loop designs, or difficult drilling conditions can extend that timeline. Your itemised estimate includes a projected timeline so you know what to expect before work begins.

Often yes. Older Jefferson County homes may have undersized electrical panels that need upgrading to support a heat pump’s startup draw, and aging ductwork sometimes requires sealing or resizing. The system evaluation checks both before the estimate is written, so any required upgrades are itemised upfront rather than discovered mid-project.

Geothermal systems need annual checks of the heat pump unit, refrigerant charge, loop pressure, electrical connections, coils, condensate drains, and air filters. The ground loop itself rarely needs attention, but loop pressure should be verified each visit. Catching small issues early keeps efficiency steady and avoids larger repairs down the road.

Once a year is the standard interval for most residential geothermal systems. Scheduling before your heaviest-use season, late summer before heating season or early spring before cooling season, means the system is checked when it matters most. High-use commercial systems may benefit from twice-yearly visits.

A thorough visit covers refrigerant charge, loop fluid pressure, coil condition, condensate drain flow, air filter condition, electrical connections, thermostat calibration, and circulation pump operation. Each item is checked against manufacturer specs so any deviation is documented rather than guessed at.

Yes. Coil cleaning, condensate drain flushing, and filter replacement or cleaning are standard tasks carried out during a maintenance visit. Keeping those components clear prevents airflow restrictions, water damage from blocked drains, and the efficiency losses that come with fouled heat-exchange surfaces.

Yes, all four are part of a complete geothermal service. Refrigerant charge is measured against manufacturer specs, thermostat and control sequencing is verified, electrical connections are inspected for corrosion or looseness, and loop pressure is tested to confirm the ground loop is sealed and circulating correctly.

Inside, the technician needs clear access to the air handler or heat pump cabinet and the loop manifold, typically in a utility room or basement. Outside, the loop connection point or wellhead needs to be accessible. No excavation is required for a standard maintenance visit unless a loop issue is found.

A standard maintenance visit is clean work. Coil cleaning uses controlled methods that contain debris, and condensate drain flushing is done with the drain line intact. Technicians work within the equipment footprint and leave the area as they found it. Drop cloths are used if the unit is in a finished space.

Before winter, verify loop antifreeze concentration, refrigerant charge, heat strip operation, and thermostat heating sequencing. Before summer, check cooling mode refrigerant charge, condensate drain flow, coil cleanliness, and fan operation. Both checks confirm the system can handle Denver’s temperature extremes without mid-season failures.

Most diagnostic visits happen within one to two business days of contact. Simple repairs, pump swaps, control board replacements, refrigerant recharges, are often completed the same visit. Loop faults that require excavation take longer, depending on ground conditions and access. You will get a timeline in the written estimate before work starts.

The technician checks loop pressure and flow rate, refrigerant charge, compressor operation, electrical connections, control board fault codes, and the circulation pump. The thermostat and zone controls are also verified. This full system evaluation is standard on every visit so that secondary faults are not missed alongside the primary one.

Yes. Loop pressure, flow rate, and refrigerant charge are checked as part of the standard system evaluation on every repair visit. These three readings together confirm whether the fault is in the refrigerant circuit, the loop, or the mechanical components, and whether any secondary issues need attention at the same time.

Yes. Every visit ends with a post-repair check to confirm the system performs as specified, correct supply temperatures, stable pressures, and no fault codes. The work area is left clean before the technician leaves. Any findings from the follow-up test are documented and shared with you.

Replacing the indoor unit alone typically takes one to two days. If the loop needs repair or the ductwork requires modification, add one to three more days depending on scope. The written estimate provided before work starts includes a timeline so you know what to expect.

No, not if the existing ground loop is in good condition. The indoor unit connects to the loop at a header inside the home, so the swap stays entirely indoors. Yard work is only needed if the loop itself requires repair or the loop field needs to be extended.

Vertical drilling requires a rig in your yard for one to three days, leaving borehole access points that are backfilled and restored after grouting. Horizontal loop work involves trenching across a portion of the yard. Both are disruptive short-term but leave no permanent surface change once complete.

The process starts with a system evaluation covering load, existing equipment condition, and altitude-adjusted sizing. A written estimate is then provided covering equipment, installation scope, and timeline. On installation day the old unit is removed, the new unit is connected to the existing loop, refrigerant and flow are commissioned, and a post-install check confirms the system performs as specified.

The consultant evaluates your heating and cooling load, reviews your existing equipment’s condition, and accounts for Denver’s altitude in sizing calculations. You then receive an itemised written estimate covering equipment, installation scope, and timeline. Nothing is left verbal.

None. The consultation itself involves no digging at all. It is a site assessment and planning visit. Any excavation or drilling only happens after you approve the written estimate and installation work is scheduled.

Yes. The written estimate produced after the site visit itemises the full installation scope, including where ground disturbance will occur. You will know which areas are affected before committing to any work.

A typical site visit runs one to two hours, depending on property size and the complexity of your existing system. The written estimate is prepared after the visit and delivered separately once the load and site data have been reviewed.

Yes. The load evaluation covers both heating and cooling demand, sized for Denver’s climate and altitude. Geothermal handles both functions from a single ground loop, so the consultation addresses the full annual cycle, not just one season.

Yes. The consultation is a planning step with no commitment to proceed. Your existing heating and cooling continues operating normally while you review the written estimate and decide whether to move forward.

Disruption varies by loop type. Horizontal loops require trenching across a significant portion of your yard; vertical loops leave a much smaller footprint. The written estimate produced after the consultation specifies exactly which areas will be disturbed and how the site will be restored.

Yes. The site evaluation covers lot dimensions, soil conditions, and bedrock depth alongside your heating and cooling load. All of those factors feed into the loop type recommendation and the sizing calculations included in the written estimate.

Partners use pressure testing and tracer gas injection to pinpoint the leak location before any ground is broken. A detectable gas is introduced into the loop, then a surface sensor traces where it escapes. This narrows the dig to a small, targeted area rather than exposing the entire loop field.

Usually not. Once the leak is pinpointed with pressure and tracer testing, most repairs require opening only a small area directly above the fault. Horizontal loops near the surface involve a shallow trench; vertical loop connections at the manifold header rarely require any yard excavation at all.

The excavation footprint depends on where the fault sits. A single pipe joint failure typically means a trench of a few feet. Manifold or header repairs at the entry point to the house may need no yard work at all. Tracer gas testing before digging keeps the disturbed area as small as possible.

Once the repair passes a pressure test, the loop is refilled with the correct antifreeze mixture, bled of air, and flow-balanced. Partners then run a post-install performance check to confirm the system is heating or cooling to specification before backfilling the excavation and restoring the surface.

A single-point repair typically takes one day from excavation to backfill, including the pressure test and system refill. More complex jobs involving multiple faults or deep vertical loop headers may run into a second day. The diagnostic phase before digging is usually completed in a few hours on the same visit.

Some surface disruption is unavoidable where excavation is needed, but targeted leak detection keeps the disturbed area small. Topsoil and sod are typically set aside and replaced after backfilling. Established trees, shrubs, and hardscaping near the loop field are noted during the site evaluation so the access route avoids them where possible.

Only above the fault location, which tracer gas testing pinpoints before any digging starts. Manifold and header faults at the building entry point often require no yard excavation at all. When digging is needed, the trench is kept as narrow and shallow as the pipe depth allows, then backfilled and restored the same day.

Trenches are typically dug 4 to 6 feet deep, which keeps the pipe below Denver’s frost line and in soil with stable year-round temperatures. Some configurations use a slinky coil layout to fit more pipe into a shorter trench, which can reduce the total footprint needed.

Expect a tracked excavator or trenching machine to cut long, narrow trenches across the yard. Once the pipe is laid and pressure-tested, the trenches are backfilled and compacted. Disturbed turf is graded level, though grass regrowth takes a season or two depending on how the yard is reseeded.

Most residential horizontal loop installations take two to four days for the ground loop portion, depending on trench length and soil conditions. Connecting the loop to the indoor heat pump unit and completing the post-install performance check adds time, so the full project typically runs three to six days on site.

The installation covers removal of the existing unit, water-side supply and return connections, refrigerant circuit work, ductwork tie-in to the air handler, electrical hookup, and a post-install startup check confirming the system performs as specified. The itemised written estimate lists every element of scope so you know exactly what is covered.

Most installations are completed in one day and are confined to the mechanical room and the duct connections nearest to it. Heating or cooling is offline during the swap, so scheduling during mild weather reduces discomfort. Work areas are protected and cleared before the crew leaves.

Frequently, yes. Older homes may have undersized panels or wiring that does not meet the amperage requirements of a current geothermal air handler. Any electrical upgrades needed are identified during the system evaluation and itemised in the written estimate before work begins.

Yes, if horizontal trenches are used, a significant portion of your yard will be excavated. Vertical drilling disturbs a much smaller surface area, typically just the borehole locations and a trench connecting them to the house. The loop type chosen during the site evaluation determines the actual footprint of the ground work.

Horizontal trenching causes the most surface disruption, affecting the full trench run plus equipment access paths. Vertical drilling limits surface work to borehole pads and a connecting trench. Either way, the site is restored after the loop is installed, topsoil is replaced and the area is graded back to its original contour.

After the loop is buried and pressure-tested, excavated areas are backfilled, topsoil is replaced, and the ground is graded to match the original contour. Lawn re-seeding or sod replacement is typically part of the restoration scope. The written estimate details what site restoration is included so there are no surprises at the end of the job.

Most residential installs take between three and seven days from ground work start to commissioning, depending on loop type, system size, and site conditions. Vertical drilling generally runs faster on the surface side but requires more drilling time per borehole. The itemised estimate includes a project timeline specific to your job.

Scheduling depends on current partner availability and permit lead times in your Denver-area jurisdiction. The evaluation and written estimate come first, and the timeline is included in that document. Contacting us early in the season typically gives more flexibility on start dates.

Every install includes a post-install check to confirm the system performs as specified. That covers loop pressure, flow rates, refrigerant charge, thermostat calibration, and measured heating and cooling output against the design load. Any deviation from spec is corrected before the job is signed off.

If a suitable well already exists, site work is limited to trenching supply and return lines from the well to the mechanical room, typically a short run. If a new well is needed, a licensed driller bores to the aquifer depth, which in the Denver area commonly ranges from 100 to 400 feet. A discharge well, if required, adds a second bore of similar depth.

The process starts with a load calculation and written estimate covering equipment, scope, and timeline. Then the well connection, supply piping, heat pump unit, and discharge system are installed. After commissioning, a post-install performance check confirms flow rates, temperatures, and system output match the specified design before the job is signed off.

Discharge options include a return well (most common in Colorado), a surface water body, or a permitted dry well. A return well reinjects water into the same aquifer at a separate bore, which avoids surface saturation entirely. Surface discharge to a pond or stream requires a state water rights permit. The right method depends on your lot, soil permeability, and local regulations.

With clean, low-mineral water, maintenance is straightforward: inspect and clean the inlet strainer once or twice a year and check heat exchanger surfaces annually. Hard or iron-rich water requires more frequent filter changes and periodic acid flushing of the heat exchanger. Installing the right filtration at the outset significantly reduces how often scaling becomes a problem.

Annual tasks include checking well pump operation, inspecting the strainer and any filtration equipment, testing water quality, and verifying heat exchanger efficiency. The heat pump unit itself needs the same checks as any geothermal system: refrigerant pressure, electrical connections, and airflow. Scheduled maintenance visits cover all of these in one appointment.

Yes. High mineral content, excessive sediment, or chemical contamination can degrade the loop pipe over time and affect heat transfer. A basic water assessment is part of the site evaluation so the loop material and antifreeze solution can be matched to actual conditions. Skipping this step risks premature pipe degradation and reduced system life.

Coiled or slinky-style HDPE pipe is weighted and sunk to the bottom of the water body, then connected to a supply and return trench that runs from the shoreline to the home’s heat pump unit. The trench is backfilled, the loop is pressure-tested, and the system is charged with an antifreeze solution before startup. A post-install check confirms flow rates and temperatures meet the design spec.

A trench is cut from the water’s edge to the home, typically 4 to 6 feet deep to stay below the frost line. Shoreline disturbance is kept to the minimum needed to feed pipe into the water. Once the loop is in place and tested, the trench is backfilled and the surface is restored as part of the standard installation scope.

The coiled pipe is attached to concrete anchors or weighted frames that hold it at the correct depth on the pond floor. This prevents the loop from floating to the surface where water temperatures are less stable. Anchor spacing and weight are sized to the loop length and the water body’s conditions.

Setup covers loop placement, anchoring, and trench pipe connections. Pressure testing confirms the closed loop holds without leaks before the system is charged. Site restoration includes backfilling the trench and returning disturbed ground to a finished condition. A post-install performance check verifies the system operates within the specified parameters.

Denver winters can push surface ice several inches thick, but the loop is anchored well below that depth where water stays above freezing. The antifreeze solution in the loop is also sized for local low temperatures. These two factors together mean normal Colorado winter conditions do not interrupt system operation.

Drilling creates a small surface footprint, usually a borehole of 4-6 inches in diameter per loop. The rig does leave track marks and a small work area, but the disturbed surface is restored after backfilling. Concrete or pavers can be cut and patched if the only viable access runs across a hard surface.

Disruption is concentrated at the borehole locations and the trench connecting loops to the mechanical room. Grass and topsoil are removed, then replaced after backfill is complete. Most homeowners see a narrow disturbed strip rather than a torn-up yard, and the area typically recovers within one growing season.

The crew drills one or more boreholes to the specified depth, inserts high-density polyethylene U-bend pipe, then backfills with thermally conductive grout. The loop headers are trenched to the mechanical room and connected to the heat pump unit. A post-install check confirms flow rates and system performance match the design spec.

The scope covers borehole drilling, HDPE U-bend loop pipe, header manifold assembly, thermally conductive grout backfill, and the trench connecting loops to the building. The itemised written estimate details each element so you know exactly what is and is not included before work starts.

After grouting and backfill, the crew removes drilling spoils, grades the disturbed soil, and replaces topsoil and sod where applicable. Hard surfaces cut for access are patched to match the surrounding finish. The post-install check happens before the site is handed back to you.

No. Denver Geothermal is an enquiry service. We arrange a local licensed geothermal installer to assess your site and carry out the work. The installer is an independent licensed HVAC contractor who performs all on-site tasks, from loop-field drilling through to commissioning.

At Denver’s elevation, air density is lower, which reduces heat-pump efficiency compared to sea-level ratings. A calculation copied from a standard table will undersize the system. The installer we arrange adjusts BTU load figures for altitude and accounts for the metro’s wide day-to-night temperature swings.

The estimate itemises drilling or trenching, loop piping and fluid, the indoor heat pump unit, any electrical work, permitting fees identified for your county or municipality, and the projected installation timeline. You see the full scope before anything is scheduled.

A loop pressure fault causes the system to short-cycle, the heat pump turns on and off repeatedly without completing a full heating or cooling cycle. That raises energy consumption and puts mechanical stress on the compressor. Left unaddressed, compressor failure is a likely outcome, which costs significantly more to fix than a loop repair.

Yes. Requirements differ by county and municipality, Jefferson, Arapahoe, Douglas, and Denver proper each have their own permit processes for ground-loop drilling and HVAC installation. The installer we arrange identifies the applicable requirements during the initial site assessment and includes them in the written scope.

A site evaluation checks lot dimensions, soil conditions, and drilling or trenching access. Vertical boreholes work on smaller lots where horizontal trenches won’t fit. The evaluation also confirms whether existing ductwork can integrate with the new system, so you get a specific answer rather than a general estimate.

Some disruption is part of the process, horizontal trenching disturbs more surface area than vertical drilling. The written scope includes surface restoration so the yard returns to a usable state after backfill. Vertical boreholes limit the footprint to the drill rig’s access area, which is smaller than a full trench layout.

Continued operation means continued repair bills and high utility costs, a failing system does not extend its useful life by running longer. Each season of delay adds repair costs that do not contribute toward a replacement. An undersized or short-cycling system also puts more wear on components, which raises the eventual repair or replacement cost.

The same system handles both. The refrigerant cycle reverses in summer to move heat out of the house, so there is no separate AC unit. Denver’s hot summers and cold winters make a single system that covers both seasons a practical fit for most homes in the metro area.

Yes. Ground-source heat pump work requires mechanical permits, and requirements vary by county and municipality across the Denver metro. Permitting requirements are identified at the first site assessment and factored into the written scope before any installation work is scheduled.

Often yes, but the home’s ductwork condition, insulation levels, and existing equipment all affect the sizing. Older homes with serviceable ductwork can usually integrate a ground-source system without a full duct replacement. The load calculation at the site evaluation accounts for these factors before any equipment is specified.

Yes. Geothermal installation typically requires a mechanical permit and, for vertical drilling, a well construction permit from the Colorado Division of Water Resources. Some municipalities also require electrical permits for the indoor unit. Your installer pulls the required permits as part of the project scope outlined in your written estimate.

A post-install performance check confirms the system operates as specified before the job is closed out. If issues arise after that, our partners handle repairs through their service operations. Ground loops carry long manufacturer warranties, typically 25 to 50 years, and indoor units are covered by equipment warranties. Geothermal heat pump repair is available if you need it.

We connect you with vetted independent local partners who hold the mechanical and contractor licenses required by Colorado and your local municipality. Confirming current license and insurance status is part of our vetting process. You can ask your matched partner for their license number and certificate of insurance before work begins.

A structured inspection is specifically designed to surface problems before they escalate. Refrigerant leaks, loose electrical connections, and low loop pressure often show measurable symptoms well before a breakdown occurs. Finding them during a scheduled visit is far less disruptive than an emergency call in the middle of winter.

Any additional work is documented in an itemised written estimate before anything is done, so you know the scope and cost upfront. Nothing proceeds without your approval. If the repair is outside the maintenance visit’s scope, it is scheduled separately so you can plan accordingly. Learn more about repair options

Yes, when the root cause is identified and corrected rather than just the symptom. A recurring refrigerant loss, for example, points to a leak that needs sealing, not just a recharge. Consistent annual visits build a service history that makes patterns visible and helps prevent the same issue from returning.

Warranty coverage depends on your equipment manufacturer’s terms and any service agreement in place. Some manufacturers require documented annual maintenance to keep the equipment warranty valid, so skipping service can void coverage. Check your equipment documentation, and ask about service agreement options when booking your visit.

Checking thermostat settings and resetting the breaker once is safe. Beyond that, geothermal systems involve pressurised refrigerant circuits and high-voltage electrical components, both require licensed technicians. Opening refrigerant lines without certification is illegal under EPA Section 608 regulations. Attempting it can also void any existing equipment warranty.

Coverage depends on your equipment manufacturer’s warranty and any extended service plan you hold. Most manufacturers cover compressors and heat exchangers for 5 to 10 years from installation. Labour warranties vary by installer. Check your original installation paperwork for terms, a technician can advise whether a fault is likely to fall within the manufacturer’s scope.

If the original fault persists after the repair, the technician will return to re-diagnose at no additional call-out charge. The written estimate documents exactly what was found and what was fixed, so there is a clear record to work from. If a deeper fault is uncovered, you will receive an updated estimate before any further work proceeds.

It will if the root cause is the indoor unit. A worn compressor, failed reversing valve, or degraded heat exchanger all cause comfort and efficiency loss that a new unit corrects. If the loop is undersized or partially failed, that must be addressed too. The evaluation identifies which part of the system is responsible before any equipment is ordered.

Hidden damage is addressed before the new unit is installed, not after. If the evaluation finds a loop leak, grout failure, or corroded header, those items are added to the written estimate with their own scope and cost. Installing a new unit on a damaged loop wastes the investment, so no work proceeds until the full picture is clear.

Yes. Any work that changes the outdoor loop configuration, adds new boreholes, or modifies the mechanical system typically requires a permit from Denver’s building department. Indoor-only unit swaps may require a mechanical permit as well. The installation scope in your written estimate will identify which permits apply to your specific project.

Yes. Every enquiry results in an itemised written estimate that covers equipment, installation scope, and timeline. Nothing is left to a verbal summary. You have a documented plan to review before any decision is made.

Yes, provided the leak was the only cause of reduced performance. Restoring correct fluid volume and pressure brings loop flow rates back to design spec, which directly restores heat exchange capacity. After the repair, partners run a post-repair check to confirm the system performs as specified before closing the site.

Yes. A pressure test is a standard step after every ground loop repair. The loop is pressurized to its rated operating pressure and held for a set period to confirm the repair holds and no secondary leaks exist. The system is only refilled and returned to service once it passes.

A properly fused or mechanically joined HDPE repair should not worsen the leak. The repaired section is pressure-tested before backfilling, so any issue is caught and corrected on the same visit. Partners conduct a post-repair check to confirm the system performs as specified before the job is closed out.

Trenching does disturb the yard surface, but the impact is temporary. Existing trees, shrubs, and hardscaping are routed around during planning. The trench is backfilled and graded after installation, and grass typically recovers within one to two growing seasons with normal watering and reseeding.

HDPE ground loop pipe is rated for 50-plus years and is fused, not glued, so joint failures are uncommon. Every installation includes a pressure test before backfilling to confirm there are no leaks. If a loop issue does arise later, it can be diagnosed and addressed through a ground loop repair service. Ground loop repair

Every installation includes a post-install performance check to confirm the system meets its specified output before the job is closed out. If performance falls short after that check, contact the installing partner directly. Ongoing issues with the ground loop itself can be assessed through a dedicated repair service. Ground loop repair

Damage is not expected when the mechanical room has adequate access. If a duct connection or electrical run requires opening a finished surface, that is identified during the system evaluation and included in the written estimate so you can plan for it. Work areas are protected throughout the installation.

Yes. Every installation includes a post-install startup check to confirm the system performs as specified. That means verifying water flow rates, refrigerant pressures, airflow, and thermostat operation before the job is signed off. You should not have to call back to get the system working correctly.

If the system does not perform as specified after the startup check, our partners return to diagnose and correct the issue. The post-install verification is specifically designed to catch problems before the crew leaves. Any issue that surfaces after that is addressed promptly rather than treated as a new service call.

Sizing starts with a load calculation that accounts for your home’s envelope, occupancy, and Denver’s altitude, not a rule-of-thumb square footage estimate. The altitude adjustment matters because equipment rated at sea level performs differently above 5,000 feet. The post-install check then confirms actual output matches the design figure.

A mismatched loop type leads to under-extraction or over-extraction of ground heat, which forces the heat pump to run longer cycles and raises operating costs. In severe cases it can cause the loop to freeze or overheat over time. The site evaluation is specifically designed to match loop type and length to your actual load and soil conditions before any ground is broken.

The post-install check measures loop pressure, flow rates, refrigerant charge, and system output against the design specification. If anything falls outside spec, it is corrected before the job closes. That documented check gives you a baseline record you can reference for any future maintenance or warranty work.

Contact us and we connect you with the installing partner to diagnose the issue. Because every install includes a documented post-install check, there is a clear performance baseline to compare against. Depending on the fault, the path forward may be a repair or a warranty claim with the equipment manufacturer.

A post-install performance check confirms flow rates and temperatures meet the specified design, catching problems early. If water quality changes over time and causes scaling or fouling, the heat exchanger can be acid-flushed and filtration upgraded. Discharge issues, such as a return well losing capacity, are addressed by our partners through ground loop repair or well rehabilitation.

Yes, directly. Colorado requires a permitted water right for any groundwater withdrawal, including geothermal use. The discharge method, return well, surface water, or dry well, each carries its own permitting path under state and sometimes county rules. Skipping this step can result in a stop-work order or required system removal, so permit review happens before any drilling begins.

If access complications arise during installation, the scope and any cost impact are reviewed with you before work continues. The upfront site evaluation is specifically designed to identify difficult access points, steep banks, or rocky shorelines so they are priced into the estimate rather than discovered mid-job.

Every installation includes a post-install performance check that confirms flow rates and system output match the design specification. If the system falls short of that spec, the issue is diagnosed and corrected. For ongoing faults after commissioning, ground loop repair covers loop-side diagnostics and remediation.

In most cases, yes. Installing a loop in a natural water body typically requires approval from Colorado water authorities and may need a local building permit. Requirements vary by county and water body type. The site evaluation identifies the applicable permits so they are secured before installation begins.

No. The vertical loop is the ground heat exchanger buried in the boreholes; the geothermal heat pump is the indoor mechanical unit that moves heat between the loop fluid and your home. Both are required for a complete system. The loop installation and the indoor unit installation are separate scopes that are coordinated together.

No. The process starts with a system evaluation that assesses site feasibility, load requirements, and equipment sizing. You receive an itemised written estimate covering scope and timeline before any commitment is made. Drilling only proceeds once you have reviewed and accepted that estimate.

Yes. Vertical borehole drilling in Colorado typically requires a well construction permit from the Colorado Division of Water Resources, and Denver may require a separate building permit for the mechanical installation. The site evaluation identifies the specific permits needed for your address so nothing is missed before drilling starts.

Yes, the federal residential clean energy credit still applies to geothermal heat pump installations in 2026 at 30% of eligible costs. This credit was extended under the Inflation Reduction Act and covers equipment and installation. Check with a tax advisor to confirm what your specific project qualifies for, as rules around eligible expenses can vary.
