HeatingWhat Happens During a Heat Pump maintenance Appointment?

You know that you should get your heat pump checked at least once a year. Regular heating maintenance is the key to your heat pump having a long and healthy life, after all. What actually happens during a maintenance appointment, though? Read on for some of the most basic areas that are serviced during your appointment.

Air Filter

The first thing a technician will likely do is inspect your air filter. You should change your filter yourself every 1-3 months, depending on how often you use it. Even so, a technician will change it for you for the sake of being thorough. A dirty air filter can compromise the ability of the heat pump to cool or heat properly, so it is important that it be kept clean.


Refrigerant is the fluid that enables the heat pump to cool air for circulation. As such, it’s a vital part of heat pump operations. Your technician will check the refrigerant level to make sure it isn’t low. The lines will also be checked to ensure that they aren’t leaking. If the refrigerant level is too low, it can be replenished fairly easily.


No matter what else may be wrong with your heat pump, your technician will always check the thermostat. The display and sensors will be inspected to verify that the thermostat is functioning properly. The temperature may also be briefly adjusted to make sure that the connection between the thermostat and the heat pump is working. Thermostat problems are common, but are also easier to repair than most issues with the actual heat pump.

Reversing Valve

The reversing valve is what enables the heat pump to act as both a heating and cooling unit. This is always checked, to ensure that both functions of the heat pump are operating as they should. First, the technician will make sure the solenoid is moving the slide properly. Then, the 4 lines into the valve will be checked for blockages.
