Heat pump maintenance in Littleton, NH. Call (877) 596-5867 to schedule.
Heat pump maintenance in Littleton, NH differs slightly from standard AC tune-ups because the same unit runs through both heating and cooling seasons. Ideally a heat pump is serviced twice a year — once in spring for the cooling season and once in fall for heating.
A complete heat pump maintenance visit includes cleaning the outdoor coil (which builds up debris running year-round), checking refrigerant charge against the unit's spec, testing the reversing valve in both modes, verifying the defrost cycle operates correctly, inspecting the auxiliary heat strips, testing capacitors and contactors, clearing the condensate drain, replacing the air filter, and confirming the thermostat is staging the system correctly.
The reversing valve check matters because a sticking valve can mean the heat pump heats when it should cool or vice versa — a common problem that costs efficiency and gets missed without proper testing. Defrost cycle verification matters because a defrost board running too often wastes energy and a board running too rarely lets ice build up on the outdoor coil.
Skipping heat pump maintenance in Littleton, NH usually shows up as higher electric bills (auxiliary heat running more than necessary), uneven temperatures, or surprise failures during weather extremes. The annual cost of proper maintenance is small compared to the repair calls or efficiency losses it prevents.
Most heat pump warranties require documented annual professional maintenance to remain valid. Call (877) 596-5867 to schedule heat pump maintenance in Littleton, NH.
