A heat pump runs its compressor and refrigerant circuit through a long, cold heating season before it ever touches the cooling side. Homes in Warren County, NJ run heat about eight months a year, from October through May. The heating load is where capacity gets tested, where defrost cycles accumulate, and where a worn contactor or a low refrigerant charge finally shows up as a comfort complaint. A contractor diagnosing a heat pump here opens the electrical panel and checks refrigerant pressure before anything else, because those two points carry the most wear from repeated cold-weather cycling.

Ductwork laid into a house built generations before heat pumps were common carries a particular record: layers of dust, degraded seals, and joints that were fitted to systems with different pressure and airflow profiles than what runs in them now. Half the homes in Warren County, New Jersey were built in 1972 or earlier (2020-2024 ACS 5-year). A contractor opening a heat pump for repair in this county often finds that the equipment itself is the straightforward part of the job, and that what slows the diagnosis is tracing a performance problem back through ductwork that was never designed around the unit it now serves. Leaking supply runs and collapsed flex at branch points can mimic refrigerant or compressor faults closely enough that a repair misses them entirely.

The Parts of a Heat Pump a Contractor Checks First

The outdoor unit sits outside the house and holds the compressor and the condenser coil. The compressor is the piece contractors go to early when a heat pump stops moving heat properly, since it does the core mechanical work. The condenser coil wraps around it and is where heat is exchanged with the outside air.

Inside the house, the air handler contains the evaporator coil and the blower fan, which pulls air across the coil and pushes it through the home. The reversing valve, housed in the outdoor unit, is what lets the system switch between heating and cooling, and a fault there shows up as a system that blows the wrong temperature. The expansion valve and refrigerant lines connect both units and are common targets when a contractor is tracing a pressure or airflow problem.

The drawing shows a typical layout, and a licensed contractor determines which parts apply and what work is needed in your specific home.
