A broken heat pump can leave your home freezing in the winter or sweltering in the summer.

Meyer Heating & Air provides expert heat pump repair services to restore your home’s climate control quickly and efficiently. When your system fails, our prompt and reliable technicians are ready to diagnose the problem and get your comfort back online.
Don’t risk DIY electrical fixes that could damage your system’s reversing valve or void your warranty. Our NATE-certified professionals ensure your equipment is repaired safely, calibrated accurately, and operating at peak efficiency.
The Importance of Professional Heat Pump Repair
Modern heat pumps are complex pieces of machinery that require precise calibration, specialized tools, and technical expertise to repair safely. Choosing a professional for your heat pump repair ensures:
- System Protection: We quickly diagnose and resolve complex issues, like defrost cycle failures, electrical faults, and low refrigerant levels, before they lead to a total compressor failure.
- Optimal Efficiency: A proper repair ensures your unit does not overwork itself, keeping your indoor temperature consistent while keeping utility bills in check.
- Safety First: Heat pumps use high voltage and pressurized refrigerant. Our certified technicians handle these hazards safely and in accordance with environmental regulations.

What to Check Before You Call Us
Because heat pumps operate differently than traditional furnaces or AC units, they have unique quirks. Save yourself time and money by checking these common culprits and normal operating modes before scheduling a diagnostic visit:
- Observe the defrost cycle: If it is cold outside and your outdoor unit stops its fan, makes a whooshing sound, or emits steam, do not panic! This is the normal defrost cycle melting frost off the coils. It should resume normal heating within 10 to 15 minutes.
- Check your thermostat and Emergency Heat: Ensure your thermostat is set to the correct mode for the season. If your thermostat says “Auxiliary Heat” or “Emergency Heat,” note that this runs your backup electric heating strips and uses significantly more energy. Emergency Heat should only be manually selected if the heat pump itself has failed.
- Check the dual circuit breakers: Heat pump systems typically have two dedicated circuit breakers. One controls the outdoor compressor unit and the other controls the indoor air handler. Ensure neither has tripped.
- Inspect your air filter: A dirty, clogged filter restricts airflow. This can cause the indoor coil to freeze during the summer or trigger high-pressure safety switches during the winter. Replace it if it is visibly dirty.
- Clear the outdoor unit: Heat pumps need clear airflow to pull heat from the outside air. Make sure there is no deep snow, thick ice, debris, or tall grass blocking the outdoor condenser unit.
Common Heat Pump Issues We Repair
Our NATE-certified technicians are highly experienced in diagnosing and repairing all major brands and models. We commonly resolve:
- Stuck in One Mode: If your heat pump is cooling but will not switch to heating (or vice versa), you likely have a faulty reversing valve that needs to be replaced.
- Blowing Cold Air in Winter: Often caused by low refrigerant, a failing compressor, or an issue with the outdoor unit’s defrost control board.
- Ice Buildup in Winter: While a light frost is normal, a heat pump completely encased in thick ice indicates a broken defrost cycle or a bad relay.
- Constant Running: If your system runs nonstop without reaching the set temperature, it may be struggling with a refrigerant leak or a severely clogged air filter.
