Repair & Restore
Get your ground-source system heating again with a structured fault diagnosis before any parts are ordered.
Common Failure Points
Skipping steps in the diagnostic sequence leads to wrong parts, repeat callouts, and a system that still does not heat.
Replacing a compressor without confirming refrigerant pressure wastes money and leaves the real cause untouched.
Refrigerant pressure is measured against the manufacturer’s specified range before any component is quoted for replacement.
A slow ground loop leak mimics compressor failure, heating output drops gradually and the wrong part gets blamed.
A dedicated pressure test on the ground loop confirms whether the antifreeze solution is holding or leaking before diagnosis moves on.
Repeated control lockout resets mask a failing control board or refrigerant charge issue until the system stops entirely.
The control board is tested for fault codes and electrical output so a lockout pattern is traced to its source, not cleared and ignored.
A weakened antifreeze concentration in the loop raises freeze risk during a Seattle heating season and reduces heat transfer efficiency.
The antifreeze mix condition is noted on every winter service call and corrected if it falls below the safe operating concentration.
Repair Scope
A structured diagnostic works through each failure point in sequence, from controls to loop, so nothing is missed and no part is ordered on a guess.
Electrical and pressure readings confirm whether the compressor has failed before a replacement is quoted or ordered.
A pressure test on the loop piping locates leaks in the antifreeze circuit that cause slow heating output loss.
Fault codes and electrical output tests identify control board failures that cause lockouts, short cycling, or no-heat faults.
Flow rate is measured and the pump is inspected for wear that reduces heat transfer between the loop and the indoor unit.
A stuck or leaking reversing valve is confirmed with pressure readings, then replaced to restore full heating and cooling operation.
Refrigerant charge is measured against the specified range to diagnose low-heat output and short cycling before other components are tested.
Settings and wiring verified as the first diagnostic step.
Filter condition checked for airflow restriction causing low heat.
Concentration noted and corrected on every winter callout.
Power supply confirmed before internal components are tested.
Why Choose Us
Geothermal systems are not standard HVAC, the contractors we connect you with work on ground-source systems specifically, not furnaces and heat pumps as a side job.
We connect you with contractors who work on ground-source systems, not general HVAC technicians unfamiliar with loop diagnostics.
A written scope of work is provided before repairs begin, so you approve the fix and the cost before anything is touched.
Refrigerant pressure, electrical output, and loop pressure tests confirm the fault before a part is ordered or quoted.
Contractors familiar with Puget Sound region soil and older housing stock diagnose loop and control issues common to retrofitted systems.
Parts are not replaced on assumption, the contractor identifies the specific failed component first, then quotes the repair.
How It Works
01
Tell us the symptoms, no heat, short cycling, error codes, and we match you with a local geothermal contractor.
02
The contractor runs a structured diagnostic from thermostat and controls through to loop pressure and major components.
03
You receive a written scope of work with the confirmed fault and repair cost before any parts are ordered or work begins.
