If you have a heat pump to handle the comfort needs of your home, you’ll soon switch over to heating mode for the first time in many months. You can expect the heat pump to make the transition smoothly, since all it has to do is change the direction the refrigerant flows and siphon out an amount of the refrigerant.
But sometimes the heat pump won’t make the change and instead stays in cooling mode. We’ll look at why this might happen—and what you can do about it.
- The thermostat: The first time that a heat pump malfunctions in any way, the first thing you should do is look over the thermostat and see that it’s set correctly. One incorrect program can cause the heat pump to fail to make the change over to heating mode. But the issue could also be that the thermostat itself is faulty and has lost its connection to the reversing valve.
- Broken reversing valve: Now, about that… the reversing valve is the key component of a heat pump that permits it to change between its two comfort modes. But like any component, the reversing valve can break down and become stuck, and this will stick the system in one mode or the other. To repair this, call on HVAC professionals to replace the reversing valve.
- Compressor trouble: This is the most serious possible malfunction. The compressor is what allows a heat pump to carry out heat exchange in either heating or cooling mode. A worn compressor can become stuck, and this needs to be repaired in a hurry or else it could fail entirely—and fixing a busted compressor is an expensive repair.
