Signs Your Heat Pump Needs Repair
Prompt attention prevents minor heat pump issues from turning into major system failures. Contact a local technician if you notice any of these warning signs:
- Stuck in One Mode: System fails to switch between heating and cooling functions due to a faulty reversing valve.
- Continuous Running: Your heat pump runs constantly without reaching the set thermostat temperature.
- Iced-Over Coils: Heavy frost or ice buildup on the outdoor coil during cold weather.
- Strange Noises: Grinding, squealing, or rattling sounds coming from the indoor or outdoor unit.
- Blowing Warm or Cold Air Inappropriately: Auxiliary heat running continuously or cooling mode producing warm air.

- Electrical & Control Testing: Inspecting capacitors, wiring connections, contactors, and thermostat calibration.
- Airflow Optimization: Cleaning indoor blower components, inspecting air filters, and clearing outdoor coil debris.
- Reversing Valve & Defrost Controls: Testing defrost cycles and safety shut-off controls for winter readiness.
Heat Pump FAQs
How does a heat pump work in cold Michigan winters?
Modern cold-climate heat pumps extract heat energy from outside air even in sub-zero temperatures. For extreme winter drops, dual-fuel systems automatically switch to a gas furnace backup to maintain heating performance.
How often should a heat pump be serviced?
Because heat pumps handle both heating and air conditioning year-round, they require professional maintenance twice a year—once in the spring before cooling season and once in the fall before winter.
Can a heat pump replace both my furnace and air conditioner?
Yes. A heat pump acts as a central air conditioner in the summer and reverses operation to heat your home in the winter, eliminating the need for separate standalone units in many homes.
