Finding Plumbing Issues Early

3 Common Problems With Heat Pumps

by Chris Bowman

Your heat pump helps to keep your home cool in the summer months and warms it up in the winter months. When your heat pump is not working, there are several reasons it could be on the fritz. Here are some common problems that can occur with your heat pump and the possible causes.

The Heat Pump Is Not Cooling

When the heat pump is blowing air, but it is not cooled air, it is possible the problem is as simple as a need to change the filter or clean the indoor coil. However, it could be more complicated. For instance, the refrigerant piping might be clogged or have another obstruction that is causing the refrigerant to be restricted. It is also possible that the refrigerant is low and needs to be refilled. 

The Heat Pump Does Not Turn On

Ideally, when you select the settings on your thermostat for the cool air or heat to start, the heat pump will respond. When the pump does not respond and will not even turn on, the problem could be a tripped circuit breaker or blown fuse. If the circuit breaker is tripped, simply flip it back to the on position. You also need to check your thermostat to ensure it is set correctly.

If the heat pump still does not turn on, the problem could be that the transformer or compressor needs to be assessed by a pro. A wiring issue could also exist, which can impact the flow of electricity to the heat pump.

It Is Too Cold

If you have adjusted your thermostat settings, but the heat pump is still making it too cool in your home, there could be an issue with the thermostat or the temperature sensor. To determine if the issue is with the sensor, move the thermostat to a more central location in your home. The current area where the thermostat is installed might be warmer than other areas of your home, which is triggering the system to turn on. If the problem persists, you could need a new thermostat or having a wiring issue. 

Unless you have experience with electrical wiring and complex troubleshooting of the heat pump, contact a HVAC technician to help you assess the problem and resolve it. If you continue to operate the heat pump and fail to get it fixed, the problem could worsen and result in a bigger heating repair
