What Goes Wrong

The repair approach matters as much as the repair itself

Mechanical faults in ground-source systems are component-specific. A generic diagnosis leads to the wrong fix.

Misread Symptoms

High amperage draw on a compressor looks like a refrigerant fault until loop flow data rules that out first.

Component Diagnosis

The installer isolates the specific component, compressor, pump, valve, or exchanger, before any part is sourced.

Scope Creep

An open-ended repair with no written scope can expand from one component to three without a clear approval point.

Itemised Written Scope

The scope names the component, the part or method, the labour, and the test procedure. Nothing is added without approval.

Unverified Output

A repaired system that is never load-tested may still deliver 15-20% below rated BTU capacity without triggering an alert.

Post-Repair Measurement

After the repair, BTU output is measured against rated capacity and loop pressure and flow rate are confirmed in writing.

Altitude Ignored

Denver sits above 5,000 ft. Replacement parts sized for sea-level performance derate output on the coldest nights.

Altitude-Adjusted Sizing

Replacement components are specified with altitude-adjusted capacity so the repaired system meets its original design load.

Component-Level Repair

Mechanical repairs scoped by component, not by the hour

A compressor fault, a pump failure, and a heat exchanger leak each have distinct symptoms and distinct repair paths.

Ground-source heat pump mechanical faults are component-specific. A compressor that draws high amperage but delivers low BTU output points to a different repair than a circulation pump that runs but moves insufficient loop flow. Accurate diagnosis determines which component is at fault before any parts are sourced.

The written repair scope names the component, the replacement part or repair method, the labour required, and the test procedure that will confirm the fix. Nothing is added to the scope without approval. That structure prevents the scope creep that turns a single-component repair into an open-ended job.

After the repair, the installer runs the system through a full heating and cooling cycle, measures BTU output against the rated capacity, and checks loop pressure and flow rate. The completed repair record is provided in writing, including the post-repair performance measurements.

Common Questions

Questions about mechanical component repair in Denver

How do I know whether my system needs a component repair or a full indoor unit replacement?

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.

What happens if I delay repairing a faulty reversing valve?

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.

Does refrigerant work on geothermal systems require any certification?

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.

My system is losing efficiency but not shutting down, is that worth repairing?

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.

How long does a typical component repair take?

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.

Will the repair work be covered by any warranty?

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.
