A contractor called out to repair a heat pump in Marshall County has to decide early on what actually caused the failure. 53 severe weather events were recorded in Marshall County, West Virginia between 2015 and 2024. At that rate, severe weather is an event in this county, not a standing condition, and blaming it for a failed component would be reaching for an easy answer. Refrigerant loss, worn contactors, and compressor failures here trace back to how long a system has run and how well it was installed, and that is where a contractor looks first.
Half the homes in Marshall County, West Virginia were built in 1961 or earlier (2020-2024 ACS 5-year). Heat pumps installed in houses of that vintage have often been through one replacement cycle already, which means the unit a contractor opens today reflects what was available and affordable at the time of that swap, not at the time the house was built. When something fails, the question is whether the part the system actually takes is still in production. Refrigerant lines, control boards, and reversing valves for older models run on shorter supply chains than parts for current equipment, and a contractor pricing a repair has to confirm availability before quoting the job.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is where most repairs begin. It holds the compressor, which moves refrigerant through the system, and the condenser coil, which sheds or draws heat depending on the season. When either goes wrong, the whole system feels it fast. The fan that pulls air across that coil is another common point of failure.
Inside the house, the air handler contains the blower motor and the evaporator coil. The blower pushes conditioned air into the home; the coil is where refrigerant does its work on the indoor air. A reversing valve connects the two sides of the system and is what allows the heat pump to shift between heating and cooling.
The drawing shows a typical layout, and a licensed contractor determines what applies to this particular house and system.

Severe Weather Events in Marshall County
Heating and cooling equipment in Marshall County works against whatever the weather throws at it, and that workload shapes how often repairs become necessary. A heat pump that runs hard through rough conditions wears differently than one that does not, which is why local weather history is part of understanding local service demand.
