A heat pump working a Cape May County winter is doing its hardest work when outdoor temperatures pull its capacity down, and the reversing valve, coils, and compressor all carry the wear from that. Homes in Cape May County, NJ run heat about seven months a year, from October through April. A contractor diagnosing a fault here checks those components against what cold-weather cycling actually does to them: refrigerant charge shifts, reversing valve seals degrade, and compressor starts under low-temperature conditions put more stress on motor windings than warm-weather cycles do. That history shapes which parts fail first and what a repair quote covers.

Half the homes in Cape May County, New Jersey were built in 1981 or earlier (2020-2024 ACS 5-year). A heat pump that has been running in a house built around that era has logged enough cycles that what a contractor finds inside the cabinet often determines whether a standard parts order closes the job or whether sourcing becomes its own project. Refrigerant lines corrode, contactors wear, and capacitors drift out of spec in ways that take time to show. The harder variable is whether replacement components for that particular system are still in regular supply or have moved to specialty-order only, and that answer does not come from the house's age alone.
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 heart of the system, and when a heat pump stops moving heat the way it should, the contractor starts there. The condenser coil wraps around it and is the next piece a contractor examines.
Inside the house, the air handler pushes conditioned air through the home and contains the evaporator coil and the blower motor, both of which are common sources of trouble. The refrigerant lines run between the two units, and the reversing valve inside the outdoor unit is the part that lets the system heat and cool. A failed reversing valve is one of the first things a contractor rules out when the system runs but delivers the wrong temperature.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which parts apply and what work is needed in your particular house.
