Precision Troubleshooting for Complex Systems
Because heat pumps contain complex reversing valves, defrost controls, and secondary electric heating coils, troubleshooting them requires specialized training. A standard technician might struggle to identify whether a heating failure is caused by a faulty thermostat signal, a failed reversing valve solenoid, or a refrigerant pressure issue. At Coatney Home Comfort, our heating specialists carry deep experience in heat pump electronics and refrigeration cycles, offering rapid, accurate diagnostics and repairs.

Common Heat Pump Warning Signs
Contact us to evaluate your heat pump if you observe any of the following symptoms:
- Stuck in One Mode: If your system blows only warm air or only cool air, the reversing valve (which directs refrigerant flow) is likely stuck or has lost electrical power.
- Outdoor Unit Covered in Ice: While a light frost is normal in winter, thick blocks of ice covering the outdoor unit indicate that the defrost cycle has failed. Operating a frozen system can destroy the compressor.
- Spike in Energy Bills (Aux Heat Always On): If your "Auxiliary Heat" or "Emergency Heat" indicator remains on constantly, your system is relying on expensive electric heating coils rather than transferring heat. This is usually caused by a thermostat configuration error, a failed sensor, or a refrigerant leak.
- Loud Screeching or Rattling: Rattling indicates loose bolts or fan blades, while screeching suggests a failing compressor or fan motor bearings.
