Geothermal Hvac Diagnostics — Georgetown TX
Geothermal system diagnostics require specialized knowledge across two interconnected systems: the refrigerant circuit inside the heat pump, and the ground loop circuit outside. Problems in either affect performance, but the symptoms can be similar. ProAir Georgetown's diagnostic protocol tests both subsystems to accurately locate faults.
Misdiagnosis of geothermal systems is common among technicians who lack ground loop experience — they often replace refrigerant circuit components when the actual problem is a ground loop flow or heat transfer issue. Our protocol tests both sides before recommending any repair.
What's Included
We measure suction and discharge pressures, superheat, and subcooling to assess the refrigerant circuit.
We measure loop flow rate and entering/leaving water temperature to evaluate ground loop performance.
We test loop fluid condition and inhibitor levels as part of every diagnostic.
We test capacitors, contactors, control boards, and wiring for electrical faults.
Every diagnostic comes with a written report of findings and recommended repairs.
