Why Won’t My Heat Pump Switch to Heating Mode?

We may not experience the below-freezing temperatures that other parts of the country do, but that doesn’t mean that our winters aren’t cold enough to necessitate a properly functioning heating system.

So, if you utilize a heat pump and have found that it won’t switch from cooling to heating mode, you may understandably be frustrating. Fortunately, you can rely on our team to quickly resolve the issue once you make an appointment with us. However, in the meantime, we’ve shared some possible issues that may be causing your heat pump to stay in cooling mode.

Thermostat Trouble

Sometimes, the problem may not be with your actual heating system at all, but rather the thermostat used to control it. These components can malfunction just like any other part of your heat pump, and may require repair. The problem might be as simple as the instrumentation becoming dirty and needing a good cleaning.

Other times, your thermostat trouble can be caused by the component’s wiring becoming frayed and corroded, cutting off the electrical flow that is needed for it to perform. Programming issues are another possible occurrence that can create an interruption in the operation of your heat pump.

Reversing Valve

The reversing valve is the actual component that allows for your heat pump to switch from cooling to heating, and vice-versa. If can get stuck in a certain position due to a faulty solenoid, which can often be repaired. However, if the valve is stuck due to a refrigerant leak or some other mechanical problem, then the valve may need replacing.

Refrigerant Leak

The refrigerant that your heat pump is supplied with during installation is needed for both cooling and heating, and should last through the lifespan of your system. So if you are losing refrigerant, it means that there is a leak, and unfortunately it won’t be able to perform as it should. This leak will create operational problems with your whole system, so be sure to call our professionals if you suspect this is your problem.
