A heat pump quoted from a catalog and installed to a generic spec is already behind before the first season turns. 82 severe weather events were recorded in Roane County, West Virginia between 2015 and 2024. At that rate, the system is not catching the odd hard storm; it is running against weather that is a standing part of what the equipment faces here. A contractor sizing a heat pump for this county has to account for that load in the equipment selection, the refrigerant charge, and how tightly the envelope is sealed around the install, because each of those decisions carries more weight here than in a place where severe weather seldom pushes the system.
Ductwork sized and routed for an older furnace does not automatically suit a heat pump, and in Roane County most of the housing stock was designed around something else entirely. Half the homes in Roane County, West Virginia were built in 1976 or earlier (2020-2024 ACS 5-year). That matters for installation because a heat pump moves a larger volume of air at a lower temperature differential than the systems much of this duct network was built to carry. A contractor installing here measures what is already in the walls before anything else gets priced. The electrical load a heat pump draws also has to be confirmed against what the panel actually supplies.
What a Heat Pump Installation Puts in Your Home
The outdoor unit is the piece most homeowners notice first. It sits on a pad beside the house and holds the compressor and the outdoor coil, which together do the core work of moving heat between outside air and the refrigerant running through the system. Inside, the air handler mounts in a utility space, attic, or closet and circulates conditioned air through the home.
A refrigerant line set runs between the two units, carrying refrigerant back and forth through insulated copper tubing. Alongside the air handler sits the expansion valve, which controls refrigerant flow, and a condensate drain line that carries away moisture pulled from indoor air during operation.
The drawing beside this text shows the general layout of these components, and a licensed contractor determines exactly how each one is positioned and connected in your specific home.
