A heat pump quoted or sized for Lewis County gets put up against a weather history that, by national standards, is relatively quiet. 83 severe weather events were recorded in Lewis County, West Virginia between 2015 and 2024. At that rate, severe weather is an event rather than a standing condition, which means a contractor diagnosing a struggling system here is not chasing storm load. Age, refrigerant state, and the quality of the original install are what drive failure. A contractor who prices a replacement without checking those first is guessing at the cause.
Ductwork laid down for a furnace was sized and routed around a different kind of airflow. Half the homes in Lewis County, West Virginia were built in 1977 or earlier (2020-2024 ACS 5-year). A heat pump moves air more slowly and more continuously, and ducts configured for a high-output furnace often have the wrong cross-section, the wrong return paths, or both to support that. A contractor putting in a heat pump here measures what is already in the walls before anything else gets priced, because the duct system is where the job either works or does not.
What a Heat Pump Installation Puts in Your Home
The outdoor unit sits on a pad beside the house and holds the compressor and the heat exchange coil that do the bulk of the work. Inside, an air handler mounts in a mechanical room, closet, or attic space and moves conditioned air through the home. Together these two cabinets are what a new installation adds to the property.
A refrigerant line set runs between the two units, connecting them through an exterior wall, and a condensate drain carries moisture away from the air handler to a floor drain or outdoors. A thermostat goes on an interior wall where it reads the living space and tells the system when to run.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the specifics of your house.
