A heat pump tune-up will make a big difference in the efficiency of your system and will lower your energy bills, as well. The U.S. Department of Energy reports that keeping an air-source heat pump properly maintained can lower your electric bills by as much as 25 percent. Additionally, routine maintenance increases the life of your system.
When a professional HVAC contractor services your heat pump, he or she will perform the following tasks:
Clean the outdoor condenser. Over time, dust and dirt accumulate on the condenser’s fins and coils that interfere with the condenser’s operation. Check the refrigerant level. The manufacturer of the heat pump specifies a narrow range of desired refrigerant levels. If it’s too high or low, it won’t operate at its stated efficiency. If the level is low, the technician likely will look for leaks, since without leaks, the refrigerant should remain at its installation level.
Clean and tighten the electrical connections. Electricity flows faster in a clean and tight environment, which saves on energy costs.
Change the air filter in the indoor blower. Dirty filters are the primary cause of heat pump problems, and the HVAC technician should show you how to do it yourself during the heat pump tune-up. Dirty filters slow the airflow through the blower and drive-up energy consumption. Keeping filters clean lengthens the life of your system.
Remove dust from the blower, including the evaporator coil. If dust covers the evaporator coil, the heat pump won’t work as efficiently. In the summer, the heat exchange process will slow, and it could cause the coil to freeze over. Frozen coils can cause indoor water damage or burn the compressor out prematurely.
Oil the motors and check the belts. Belts can stretch over time and wear out.
Inspect ductwork and measure airflow. Leaking ducts raise energy bills since the equipment has to work harder to compensate for the lost conditioned air.
Calibrate the thermostat and check the reversing valve. It’s important that this work accurately and dependably so the system heats in the winter and cools in the summer.
