My Heat Pump Isn’t Changing Modes

We are still enjoying pretty warm weather here in Orlando, but once the sun goes down, our evenings are getting pretty cool. If you have pressed the “heat” button on your heat pump’s thermostat only to find that it isn’t giving you warm air, it is time to give the HVAC pros from Certified Air Systems, Inc., a call. There can be a few reasons why your heat pump won’t switch to heating mode, but it’s very important to allow an expert to find out the issue.

Why Your Heat Pump Won’t Switch

Here are some of the more common reasons why your heat pump won’t switch to heating mode:

  • The solenoid on the reversing valve isn’t working – the reversing valve is the component that allows your heat pump to switch between heating and cooling. Inside this valve is a sliding mechanism, but to get the mechanism to slide, a small, electronic component has to give it a little push. That component is the solenoid. Sometimes the solenoid’s wiring can corrode or the components of the solenoid breakdown. The good news is that if it is the solenoid that is causing the problem, it can be replaced.
  • The sliding mechanism is stuck – sometimes a heat pump can become stuck. If this is what has happened to your heat pump, this means the sliding mechanism has become stuck in a mode or in-between modes. Unfortunately, this kind of problem usually is repaired by replacing the reversing valve.
  • There’s a refrigerant leak – if the refrigerant leak is not in the reversing valve, the leak can be repaired and your system recharged. However, if the leak is inside the reversing valve, the valve will need to be replaced.
