What Goes Wrong

The quiet ways a ground-source system loses efficiency

Most maintenance failures are invisible until the utility bill or a cold room makes them obvious.

Skipped Loop Check

Low loop pressure reduces BTU delivery without triggering an alarm, the system just runs longer and costs more.

Pressure & Flow Verification

Every visit measures loop pressure and flow rate and documents the readings against the design spec.

Fouled Heat Exchanger

Scale buildup on the heat exchanger surface cuts heat transfer efficiency, raising run time and compressor wear.

Heat Exchanger Inspection

Each maintenance visit includes a visual and performance inspection of the heat exchanger to catch fouling before it compounds.

Diluted Freeze Fluid

Colorado winters demand correct antifreeze concentration in outdoor lines, a diluted mix risks loop freeze and cracked fittings.

Freeze Protection Test

The installer tests freeze protection fluid concentration and corrects it to the level the loop field requires for Denver winters.

No Service History

A system with no documented maintenance record can void manufacturer warranties and complicate a future property sale.

Documented Visit Records

We provide a written record of every measurement taken, giving you a service history that satisfies warranty and disclosure requirements.

Scheduled Upkeep

Maintenance that keeps your ground-source system at rated output

Small efficiency losses in a geothermal system accumulate silently until a utility bill or a cold room makes them obvious.

Ground-source heat pumps have fewer moving parts than forced-air furnaces, but the loop field and heat exchanger still need periodic attention. Loop fluid concentration, pressure, and flow rate all affect BTU delivery, a drop in any one of them reduces the efficiency the system was sized to achieve.

A maintenance visit covers refrigerant charge verification, heat exchanger inspection for fouling, blower and pump motor checks, and a review of freeze protection fluid concentration in outdoor lines. Colorado winters make that last item a Colorado-specific requirement, not an optional add-on.

We schedule the visit, provide a written record of every measurement taken, and flag any items that need attention before they become repairs. You keep a documented service history, which matters for warranty compliance and future resale.

Why Choose Us

Why Denver Geothermal for ground-source maintenance?

Maintenance on a ground-source system is only as useful as the documentation and follow-through behind it.

Evaluation Before Every Visit

We assess system condition, existing equipment, and altitude-adjusted sizing before scheduling any maintenance work.

Itemised Written Estimates

Every scope of work is listed line by line in writing, equipment, labor, and timeline, before anything is confirmed.

Visit Scheduled

Every visit we schedule is scoped for ground-source systems, not general HVAC work unfamiliar with loop fields.

Post-Visit Performance Check

After the maintenance visit, a follow-up check confirms the system is back at its specified output before the job is closed.

Written Measurement Records

Every reading taken during the visit is documented and handed to you, building a service history that supports warranty claims.

Common Questions

Geothermal maintenance questions, answered plainly

  • Does a geothermal system really need annual service if the ground loop lasts decades?

    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.

  • Can a homeowner just change the filter and skip the rest?

    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.

  • What happens if I delay a full inspection when the system seems fine?

    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.

  • How often should a geothermal system be serviced?

    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.

  • What is checked during a full geothermal maintenance visit?

    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.

  • Do I need to do anything to prepare before the service visit?

    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 those areas can be checked first.
