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

As we start to move into the cooler time of the year, our heat pumps will beging switching over to their heating modes. Eventually, they’ll be set in heating mode for good—or at least until spring comes around!

But what if you turn on your heat pump for the first time, or the second or third time, and it won’t change over and start blowing our warm air? Obviously, this is a problem. There are a couple of possible explanations for this behavior, which we’ll examine below.

  • Thermostat problems: Whenever you run into any odd behavior from your heat pump, first take a look at the thermostat to see if there’s a mistake with its setting or programming. Sometimes the problem is as simple as that. Or, the thermostat could be broken. A lost connection between the thermostat and the reversing valve (more on this part below) will mean the heat pump won’t be able to change between heating and cooling mode. Only HVAC professionals can repair a broken thermostat.
  • Broken reversing valve: The main component of a heat pump that permits it to work at both cooling and heating a home is the reversing valve. This mechanical valve controls the direction that refrigerant flows through the system. Should it become stuck or break in any way, the heat pump will remain in one mode. Repair technicians can solve the problem by either fixing or replacing the reversing valve.
  • Compressor issues: The compressor is the heart of the heat pump, the device that gives energy to the refrigerant to make it circulate. If the compressor becomes stuck or the motor that runs it fails, the heat pump won’t produce either heating or cooling. If repair technicians get to the compressor in time, they might be able to prevent it from burning out, which is one of the more catastrophic malfunctions for a heat pump.
