A contractor quoting a heat pump install in Berkeley County has to size for what the equipment will actually run against, not for an average load pulled from a spec sheet. 138 severe weather events were recorded in Berkeley County, West Virginia between 2015 and 2024. At that rate, severe weather is part of the normal operating year, and a system undersized or poorly installed for these conditions will work against its own efficiency ceiling from the first cooling season. Refrigerant line placement, equipment mounting, and electrical supply all carry more weight in an area where the system is pushed hard on a regular basis.
Ductwork sized and routed for a conventional system does not automatically carry a heat pump's airflow requirements, and in a county where much of the housing was built for exactly that older equipment, the existing duct layout is where a contractor spends real time before anything else gets priced. Half the homes in Berkeley County, West Virginia were built in 1996 or earlier (2020-2024 ACS 5-year). A house from that era often has duct runs, plenums, and return configurations that made sense for what was installed then. A heat pump moves air at different static pressures, and whether the existing network handles that is something a contractor measures, not assumes.
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 exchanger coil that face the outside air. The indoor air handler mounts inside, usually in a utility closet, basement, or attic, and moves conditioned air through the home. These two units are the core of what a contractor puts in place.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two pieces through a small penetration in the wall. A thermostat goes on an interior wall and gives the homeowner control over the whole system. The condensate drain line runs from the air handler to a floor drain or outside.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines exactly what fits your house and how each piece gets positioned.
