A contractor quoting a heat pump installation in Greenbrier County has to treat sizing as a site-specific calculation, not a catalog lookup by square footage. 160 severe weather events were recorded in Greenbrier County, West Virginia between 2015 and 2024. At that rate of severe weather, the heating and cooling loads this system will run against are not edge cases a installer plans around once and forgets. The refrigerant line routing, the placement of the outdoor unit, and the rated capacity all have to hold up against what this county's weather regularly demands, and a contractor who knows this area prices and plans accordingly.
Ductwork and electrical panels in the older portions of Greenbrier County's housing stock were sized for the systems that were standard when those houses went up, and heat pumps draw on both differently than what most of that stock was originally built around. Half the homes in Greenbrier County, West Virginia were built in 1977 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump installation here measures whether the existing ducts can move the volume a new unit requires, and whether the panel can handle the load, before any equipment decision gets made. Those are the two variables that determine what the full job costs and how long it takes to complete.
What Gets Installed With a New Heat Pump
The outdoor unit sits on a pad beside the house and holds the compressor and the coil that pulls heat from outside air. The indoor air handler mounts inside, usually in a mechanical room, closet, or attic, and it pushes conditioned air through the home. Together these two units are the core of what a contractor sets in place.
A refrigerant line set runs between the outdoor unit and the air handler, carrying refrigerant back and forth through insulated copper tubing. 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 nearby drain, carrying away moisture pulled from indoor air.
The drawing shows a typical layout, and a licensed contractor determines what fits the specifics of your house.

Severe Weather Events in Greenbrier County
Weather in Greenbrier County puts direct pressure on heating and cooling equipment: temperature swings, storm loads, and power stress all shape how hard a heat pump has to work and how long it holds up. Sizing and installing that equipment right is a local decision, and what the weather does here is part of that calculation.
