A contractor quoting a heat pump install in McDowell County has to settle the sizing question against what the climate actually asks of the equipment year to year. 87 severe weather events were recorded in McDowell County, West Virginia between 2015 and 2024. That puts this area in a middling range of weather load, not a punishing one. What that means for installation work is direct: the spec is driven more by the thermal demands of the specific house and the quality of the duct layout than by weather as an overriding variable. A contractor who gets the Manual J calculation right and seals the system properly has done the job the county's climate requires.
Ductwork laid down for a different system does not automatically serve a heat pump, and in McDowell County the gap between what a house was built for and what a contractor is now installing into it is wide enough to be the first thing on the job sheet. Half the homes in McDowell County, West Virginia were built in 1958 or earlier (2020-2024 ACS 5-year). That span means the ducts and the electrical service in a typical house here were put in for older equipment, and a contractor assessing a heat pump installation has to open walls and pull panels before the quote is real. What the existing ductwork can handle, and what the panel will supply, are the two questions that shape the rest of the job.
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 condenser coil. These are the parts doing the heaviest work. Inside, the air handler mounts in a mechanical room, closet, or attic and pushes conditioned air through the home.
A refrigerant line set runs between the two units, connecting the outdoor pad to the air handler. A thermostat goes on an interior wall where it can read the living space and signal both units to respond.
The drawing shows the standard layout, and a licensed contractor determines exactly how each piece fits the specific house.

Severe Weather in McDowell County
Weather swings drive how hard heating and cooling equipment has to work, and McDowell County has its own pattern of storms and temperature stress. A heat pump sized and installed for local conditions handles that load differently than one spec'd for somewhere else.
