When Your Heat Pump Won’t Switch Modes: What to Do

With temperatures still relatively mild here compared to other parts of the country, it may be hard to imagine how many people are using their heaters on a regular basis right now. Although, when temperatures are as high as they are during the majority of our summers, anything below 50 degrees at night could seem pretty chilly!

So perhaps you are one of those homeowners who has decided to switch their heat pump over to heating mode to begin using for warmth. But what if it won’t switch to heating mode? What should you do then?

Check Your Thermostat

The thermostat is the component that cues your heat pump to switch modes. Thermostats can malfunction just like any other component of your HVAC system, and may require repair or an upgrade. Sometimes the problem is as simple as dust or dirt that got into the internal components.

Or it may be that the wires connecting your thermostat became frayed and corroded. Do remember that in the case of an electrical problem, only a professional should inspect and repair a thermostat.

Is Your Refrigerant Leaking?

Your heat pump is supplied with an exact amount of refrigerant upon installation in order to operate as it should, whether the system is cooling or heating your living space. During the winter, the refrigerant absorbs the heat in the surrounding air so your system can heat your home. This process is impossible, however, if the refrigerant is leaking.

Your Reversing Valve May Be Stuck

The reversing valve of your heat pump is the actual component that enables the system to switch from cooling to heating mode. This can get stuck in a certain position, sometimes due to an issue with a component called the solenoid. Fortunately, this can be repaired. Be sure to call a professional to determine what your heat pump issues are.
