Help! My Heat Pump Won’t Switch to Heating Mode

We are at the time of year that if you haven’t already, it’s certainly just about time to switch your heat pump from cooling to heating. But what if your heat pump won’t switch? There are a few reasons this may occur. There’s no need to panic: the problem may be very minor or it may even be unrelated to the heat pump itself. Our technicians can handle any heat pump repair needs that come our way! In the meantime, here are a few possible reasons your heat pump won’t switch modes.

Thermostat Issue

The thermostat is the “brain” of any HVAC system, including your heat pump. These components can malfunction just as any other component and may need repair. Sometimes, the instrumentation within the thermostat could become dusty and dirty, which affects how it operates.

The wires that connect the thermostat to your system can become frayed or corroded, which will cut off electrical flow. Or, it can be as simple as a problem with programming. First, check to ensure your thermostat is set at the correct temperature. Then, if you are still experiencing problems, contact a professional technician.

Leaking Refrigerant

Your heat pump needs a specific amount of refrigerant to function as it should, whether or not the system is in cooling mode or in heating mode. During the winter, this refrigerant absorbs the heat in the surrounding air so your system can heat your home. However, if there’s a leak somewhere in the system, then your heat pump can’t function as it should, and you’ll probably notice lukewarm air coming from your vents—which you can mistake for your system not heating.

Reversing Valve Malfunction

Your heat pump’s reversing valve is what allows the appliance to switch from cooling mode to heating mode. It can get stuck in a certain position, whether it be a specific mode or in between modes. If the reason for the immobility is traced to the solenoid, then the solenoid can be repaired. However, if it’s attributed to another problem within your system, it might need to be replaced.
