A contractor quoting a heat pump installation in Mason County has to account for how regularly severe weather runs through this area before they can size equipment or specify components correctly. 108 severe weather events were recorded in Mason County, West Virginia between 2015 and 2024. At that rate of recurring stress, a system undersized or poorly sealed at installation starts behind. The refrigerant line connections, the outdoor unit mounting, and the electrical supply all have to be specified for a climate that pushes equipment on a regular basis, not for mild steady conditions. A contractor who skips that local calibration leaves the homeowner with a system that was wrong for this place from day one.
Existing ductwork is what a heat pump installation turns on in this county. Half the homes in Mason County, West Virginia were built in 1978 or earlier (2020-2024 ACS 5-year). Houses built that long ago were fitted with duct systems sized and routed for the equipment of that era, and a heat pump draws air differently than what those ducts were originally built around. A contractor who quotes the new unit without pressure-testing or walking the existing runs is pricing the job before the job is understood. The duct system is where the installation either holds or doesn't.
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 coil that exchange heat with the outside air. Inside, an air handler mounts in a utility space, closet, or attic and moves conditioned air through the home. These two units are what a contractor sets in place.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the refrigerant that links the two. A thermostat mounts on an interior wall and gives the homeowner control over the system. Together, these connections tie the indoor and outdoor sides into a single working system.
The drawing shows a typical layout, and a licensed contractor determines exactly what fits the configuration of your home.
