What makes a heat pump stop working?

When a heat pump stops working abruptly, it will cause a lot of discomfort for the homeowners. It is worse if you depend on the heat pump to keep the house warm during the winter. Furthermore, it becomes worse if you need to learn how to troubleshoot the heat pump to find out if it is a minor issue. 

To learn some troubleshooting tips when your heat pump stops working, read this article. Try these steps before you call a technician to fix your heat pump.

Check the thermostat power

Technicians always advise that the thermostat is the first thing you should check when your heat pump stops working. Find out if the thermostat is powered or not. If a battery powers the unit, then you may need to change the battery. Also, check your home’s electrical panel if the unit is hardwired. In addition, check the circuit breaker or fuse that controls the thermostat.

Check unit power

After confirming that the thermostat is powered, you may have to check if other heat pump components have power too. Most often, the additional heat pump components have their own switches and dedicated circuits. More so, find out if the button on the outside unit or on the exterior wall is connected correctly. 

Check thermostat settings

The thermostat is an essential part of the heat pump that cannot be ignored. Also, the settings of the thermostat could affect the functionality of the heat pump. In addition, make sure the thermostat settings allow the heat pump to work effectively. 

Check air filters

Your heat pump can only work effectively if the air filter is clear. Moreover, a clogged air filter is one of the most typical reasons a heat pump fails to work sometimes. When the air filter is clogged, it obstructs the air that should be flowing through it. Examine your air filter and check for debris. Not to mention, you can either replace the air filter or wash it.

Call a heat pump expert

You can call a heat pump expert after you have tried out some of the troubleshooting methods outlined above. Also, you need to ensure that the heat pump expert you call to fix your system is certified and understands how KVAC works. But before you call a heat pump technician, ensure that you have tried all the troubleshooting tips highlighted here. 


Before the winter season starts, check the heating systems to avoid sudden changes. Just to add, turn on the heat pump and make sure the components of the unit are working effectively. One thing that affects the heat pump so quickly is dust and debris. Therefore, you need to clean the heat pump air filters often, even when you are not using them. 

Finally, choose a technician who is certified to deal with HVAC systems. Book appointments with the technicians for regular maintenance of the heat pump, too. For heat pump installation in Laval, reach out to Confort Prestige
