A heat pump repair here starts with a question most diagnostics skip in quieter areas: which components failed because this system has been running hard against genuinely demanding conditions, and which failed because the part was ready to go regardless. 138 severe weather events were recorded in Berkeley County, West Virginia between 2015 and 2024. At that rate, refrigerant seals, capacitors, and contactor points accumulate stress that shows up differently than straightforward age-related failure. A contractor who does not account for that distinction will replace the wrong part first.

Ductwork put in for one system and now running a different one is not where a heat pump repair usually stalls in this county. Half the homes in Berkeley County, West Virginia were built in 1996 or earlier (2020-2024 ACS 5-year). That means the equipment a contractor opens today is almost certainly not what went in when the house was built, and the repair question is about what that specific unit turns out to contain: whether the compressor has shed capacity, whether the reversing valve seats cleanly, and whether the replacement parts it requires are still in production or have to be sourced on delay. A house this old does not predict what is wrong; the opened system does.

The Parts of a Heat Pump a Contractor Checks First

The outdoor unit is where most repair calls begin. It sits outside the house and holds the compressor, the refrigerant coil, and the fan that moves air across it. When the system stops heating or cooling, a contractor starts here, checking whether the compressor is running, whether the coil is fouled or damaged, and whether refrigerant pressure reads where it should.

Inside the house, the air handler pushes conditioned air through the home and contains its own coil, a blower motor, and the expansion valve that controls refrigerant flow between the two units. A refrigerant line set runs between the outdoor unit and the air handler, and the thermostat sits on a wall and tells the whole system when to run. Faults in the blower motor, a failed valve, a refrigerant leak in the line set, or a miscalibrated thermostat are all things a contractor traces before deciding what the repair is.

The drawing shows the general layout of a heat pump system, and a licensed contractor determines what applies to your particular house.
