Heat Pump Repair in Salt Lake City

Heats but won't cool, or cools but won't heat. Usually the reversing valve, which is the component that switches the system between modes.

Icing up in heat mode. Some frost is normal in cold weather — the system runs a defrost cycle to clear it. Persistent ice means the defrost board, the sensor, or the outdoor fan.

Stuck in defrost. The system runs the defrost cycle continuously and never gets back to heating.

Running constantly without reaching temperature. Often low refrigerant, which means a leak, or a failing compressor.

Auxiliary heat running all the time. Expensive, and usually means the heat pump itself isn't keeping up.

Outdoor unit won't start. Capacitors, contactors or control boards, same as an AC.

A heat pump in heat mode is running the refrigeration cycle backwards. Reversing valves, defrost boards and outdoor sensors have no equivalent on a standard system, and a technician who mostly services furnaces can misread the symptoms.

We service them regularly, including in cold weather when their behavior is least intuitive.

Some frost on the outdoor unit in winter is normal. If it clears periodically, the defrost cycle is working.

If it's encased in ice, or if auxiliary heat seems to be running constantly, that's worth a call.

Check the filter too — restricted airflow causes problems in both modes.
