Heat pumps that are utilized as the primary heating and cooling systems rather than backups should be serviced once or twice a year. Heat pumps, like any other heating or cooling equipment, benefit from routine preventative maintenance. Heat pump maintenance regularly maintains the system working properly.
It also protects the compressor and other components from becoming damaged in the first place, thus protecting the heating and cooling investment. Periodic maintenance also reduces the likelihood of unexpected malfunctions, which is important for ensuring heat pump system reliability.
