A contractor quoting a heat pump repair in McDowell County has to settle one question before anything else: what actually drove the failure. 87 severe weather events were recorded in McDowell County, West Virginia between 2015 and 2024. At that rate, severe weather is a real but occasional factor, and placing it at the center of a diagnosis would be reaching. Age of components, refrigerant charge, and how well the original install was done are what a contractor checks first, because those are what break systems at this frequency of weather exposure.
Half the homes in McDowell County, West Virginia were built in 1958 or earlier (2020-2024 ACS 5-year). A heat pump sitting in a house that age almost certainly went in long after the house was finished, which means the system has its own separate history from the structure around it. When a repair call comes in, what matters is what the contractor finds once the unit is open: the condition of the compressor, the coil, the reversing valve, and whether replacement parts for that particular model are still in production. A system running in stock this old has had time to accumulate wear the age of the building alone does not predict.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is where most repairs begin. It holds the compressor, which is the heart of the system, along with the condenser coil and a fan that moves air across it. When the system short-cycles, stops heating or cooling, or makes noise, the contractor starts here.
Inside the house, the air handler pulls return air across an evaporator coil and pushes conditioned air back through the home. The reversing valve, which sits in the refrigerant line and switches the system between heating and cooling modes, is a frequent repair point as well. The expansion valve and refrigerant lines connecting both units round out what a contractor traces when the outdoor unit checks out fine.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system.
