Like most HVAC equipment, air-source heat pumps can provide a comfortable indoor environment, as well as save energy, if they are installed and maintained properly. The last point is key, notes the U.S. Department of Energy (DOE), as the difference between the energy consumption of a well-maintained heat pump and a severely neglected one ranges 10-25 percent.
Regular maintenance is even more crucial for newer heat pumps, whose efficiency decreases greatly if not properly maintained, said Rob McClintock, president, McClintock Heating, Cooling & Electrical Inc., Matthews, N.C. McClintock, who also operates as a Trane comfort specialist, said, “The system must be properly calibrated, lubricated, and tuned, otherwise it won’t last nearly as long or could even fail prematurely. We recommend homeowners service their heat pumps at least once a year, though twice a year is ideal to ensure the systems are properly cleaned and tuned prior to the changing seasons.”
