Heat Pumps Need Maintenance Twice a Year

service-markerSpring is the time when we encourage homeowners to schedule their annual maintenance for their cooling systems. This is a season when HVAC technicians have less crowded schedules because they’re responding to fewer emergency calls for busted furnaces and air conditioners. It’s therefore easier to schedule a convenient appointment for technicians to come to your house and take care of all the necessary inspections, cleaning, and adjustments to ensure your air conditioner is ready for the summer heat.

But if you have a heat pump for your home comfort, and it was professionally maintained back in the fall, is it necessary to have the service again?

The answer is “absolutely!”

A Heat Pump Does Two Jobs—And Needs Two Maintenance Visits

Think of maintenance not so much in terms of “heating system maintenance” and “air conditioning system maintenance,” but as “HVAC system maintenance.” You need to prepare the HVAC system to handle the rigors of each coming season of extreme weather. For homes that use a combination HVAC system of a furnace and air conditioner, technicians need to come in fall to work primarily on the furnace and in spring for the air conditioner. A number of jobs are the same for both, such as checking the air handler and blower and tightening electrical connections.

If you have a heat pump, you’ve got heating and air conditioning combined in a single unit—but it’s still an HVAC system that requires checks before each of the extreme weather seasons.

An important thing to remember here is that a heat pump isn’t two separate units packaged together. A heat pump uses the same components to run whether in heating or cooling mode. The compressor runs no matter what, circulating refrigerant through two sets of coils, indoors and outdoors, and the blower fan sends the cooled air into the ventilation system. The only difference between the two modes is the direction the refrigerant moves, which changes the direction the heat pump moves heat.

A full winter of work for a heat pump places immense stress on its components, particularly the compressor, which is the heart of the system. A compressor requires special attention before winter and summer to see that it isn’t wearing down too fast. If the compressor fails, it often means the entire heat pump must be changed. Missing out on either the spring or fall maintenance can mean a compressor dying years before its time.

Cleaning the interior of the heat pump also needs to be done twice a year. Lots of dust, dirt, and other grime can build up over the winter, and this is the #1 cause for a heat pump to start running at poor energy efficiency. Spring cleaning of coils, motors, and other components is essential for quality performance.
