How we repair your Heat Pump
A heat pump is an outdoor unit and indoor air handler that move heat into the house in winter and out in summer by reversing the refrigerant flow. A heat pump relies on a heat source, safety controls such as limit switches and flame sensors, blowers or circulator pumps, and a thermostat. A technician checks the ignition and safety sequence, airflow or water flow, and electrical controls.

Common Heat Pump problems we fix
What usually causes each symptom, and what our technician checks to confirm it.
Unit runs but does not cool
- Likely causes
- A failed run capacitor, a compressor not starting, a reversing valve stuck in heat, or a refrigerant leak.
- What our technician checks
- The capacitor and compressor are tested and refrigerant pressures and valve position are checked.
Outdoor unit covered in ice
- Likely causes
- A failed defrost control board, a bad defrost sensor, a stuck outdoor fan, or low airflow.
- What our technician checks
- The defrost board is forced into defrost, the sensor is tested, and outdoor fan operation is verified.
Blowing cool air in heat mode
- Likely causes
- A stuck reversing valve, low refrigerant, a defrost cycle in progress, or auxiliary heat not engaging in cold weather.
- What our technician checks
- The technician checks reversing valve solenoid voltage, measures pressures, and tests auxiliary heat strips and sequencers.
Emergency heat light on
- Likely causes
- A thermostat that has locked out the compressor due to a fault, a tripped outdoor breaker, or a failed outdoor unit.
- What our technician checks
- Outdoor unit power and operation are verified and thermostat fault settings are reviewed.
High electric bills in winter
- Likely causes
- Auxiliary heat running too often from a thermostat setup issue, low charge, or a failed outdoor temperature sensor.
- What our technician checks
- Thermostat staging settings are reviewed and the heat pump capacity is checked against outdoor temperature.
Whooshing noise every so often
- Likely causes
- Normal defrost cycle reversal, or a valve shifting loudly because of high pressure difference.
- What our technician checks
- Defrost timing and operation are observed to confirm normal behavior or a fault.
Quick checks you can do safely
- Check the thermostat mode and whether emergency heat is turned on.
- Replace the air filter at the indoor unit.
- Make sure the outdoor breaker or disconnect has not tripped.
- Clear snow and ice buildup away from the base of the outdoor unit.
- Allow a few minutes for a defrost cycle to finish before assuming a fault.
Safety first: Heat pumps carry high voltage, charged capacitors and pressurized refrigerant, so electrical and refrigerant work should be left to a certified technician.
