My Heat Pump Won’t Turn to Heating Mode

Changing your Lexington heat pump from summer cooling to winter heating is usually as simple as a flip of a switch. But if your switch doesn’t flip, what should you do? Below are a few common reasons your heat pump may not switch easily into heating mode. Rest assured that Climate Control can fix these problems easily — just give us a call anytime you’re having trouble with your heat pump.

Thermostat issues may cause heat pump problems

Just like with a conventional furnace, the thermostat is your key to communicating with your heat pump. If your heat pump won’t switch to heating mode, a thermostat malfunction could be to blame. Dust and dirt can accumulate inside the thermostat, damaging its sensitive instrumentation. Wiring can be compromised or batteries may go dead, preventing the thermostat from getting the needed power. Programming problems can also restrict the functioning of your heat pump. Our NATE-certified HVAC technicians can accurately diagnose and repair any thermostat-related issues which are preventing your heat pump from doing its job.

Problems with the reversing valve may be to blame

The system’s reversing valve is the component which makes it possible for your heat pump to switch between cooling and heating modes. It is possible that the reversing valve could become stuck in position, or stuck between modes, preventing you from flipping it over to heating mode. The solenoid may be to blame, and require repair. If the reversing valve is compromised due to refrigerant leaks, it must be replaced.

Refrigerant leaks could be the cause

Exact quantities of refrigerant are needed for the system to operate correctly in cooling or heating modes. To heat your home, the refrigerant absorbs thermal energy. If refrigerant is leaking, the system won’t operate properly. A skilled professional is needed to diagnose and fix any refrigerant issues, as certification is required for handling refrigerant.
