Cold Air Coming from Your Heat Pump: What’s Wrong?

There are many reasons why you should choose a heat pump to both cool and heat your home. First off, it’s very versatile in that it is a 2-in-1 system. Also, heat pumps work best in climates such as ours—hot summers and mild winters.

Of course, a heat pump can only be fully functional if it’s taken care of. The first step to caring for your heat pump is scheduling maintenance twice a year. Next, if something is wrong with your heat pump, you should contact professionals for repairs right away to prevent further damage. One of the most common repair needs we receive calls for is a heat pump that is only blowing cold air during the winter.

Troubleshooting Your Heat Pump

To understand what can go wrong with a heat pump, it’s first important to understand how it works. It uses the process of heat exchange through the cycling of refrigerant for both cooling and heating, and to alternate between one or the other it changes the direction of the refrigerant’s flow. If you notice it’s not heating, then your heat pump system may be struggling to change the direction of the refrigerant.

Before we jump the gun on this, however, go ahead and check he thermostat. Ensure that it’s set to your desired temperature and that it is not still in cooling mode. You’ll want to inspect the programming too—is it letting you set the temperature where you need it? You may have a faulty thermostat rather than an actual issue with your heat pump.

In the absence of refrigerant or thermostat troubles, what you are most likely dealing with is a heat pump that is stuck in cooling mode due to a broken reversing valve. This is the component that makes your heat pump different from a standalone HVAC unit: it’s what enables the change in the direction of the refrigerant. Any failure of this valve will keep the heat pump locked in one mode, so repair or replacement of this component becomes necessary.
