For a heat pump, the heating season is where the hard work lives. Homes in Salem County, NJ run heat about seven months a year, from October through April. Pulling heat from outdoor air when temperatures drop is the condition that strains the refrigerant circuit, the reversing valve, and the defrost controls most. A contractor diagnosing a repair here checks those components first, because they carry the load that cold months produce. The compressor may show wear too, but a reversing valve that is sluggish or a defrost board that is misfiring will account for losses a homeowner notices long before the compressor fully quits.
Half the homes in Salem County, New Jersey were built in 1962 or earlier (2020-2024 ACS 5-year). For a heat pump repair in stock like this, what the opened unit actually contains drives the job. Refrigerant lines may have been spliced. Electrical connections carry the history of whatever ran before. A contractor pulling a cover here is sorting through those layers before they can say what the repair is, and the parts a system of this age takes are not always current catalog items, which changes both what gets ordered and how long the work takes.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and condenser coil. These are the pieces a contractor goes to when the system is not moving heat at all. A failed compressor, a refrigerant leak at the coil, or a seized fan motor in that cabinet are among the first things a technician rules in or out.
The air handler lives inside, usually in a utility closet, attic, or basement, and it holds the indoor coil and the blower that pushes conditioned air through the house. The reversing valve, which directs the system between heating and cooling, sits in the outdoor unit and is another piece a contractor examines when the system runs but delivers the wrong temperature.
