Heat pumps are complex systems that require specialized knowledge for proper diagnosis and repair. Because heat pumps provide both heating and cooling, problems can manifest differently depending on the season. Our technicians are trained to troubleshoot heat pumps in both modes and identify the root cause of any issue. Common heat pump problems we repair include inadequate heating or cooling, failure to switch between modes, frozen outdoor unit, refrigerant leaks, compressor issues, fan motor failures, defrost problems, and reversing valve malfunctions. We also address thermostat and control board issues. The reversing valve is a component unique to heat pumps that allows the system to switch between heating and cooling. When this valve fails, it can cause the heat pump to get stuck in one mode. Our technicians have extensive experience diagnosing and repairing reversing valve issues. We service all types of heat pumps, including ducted split systems, packaged units, ductless mini-splits, and hybrid systems. We're factory-trained on leading brands including Carrier, Trane, Lennox, Mitsubishi, Daikin, and Fujitsu.

Frequently Asked Questions

Why is my heat pump not heating?

Common causes include low refrigerant, a faulty reversing valve, defrost issues, or thermostat problems. If the unit is icing up or the outdoor fan isn't running, don't wait to call—these issues can cause compressor damage.

My heat pump runs but doesn't heat well. Why?

Heat pumps produce lower-temperature air than furnaces, which can feel cool even when working properly. However, if output has decreased, causes may include low refrigerant, dirty coils, or compressor issues.
