A contractor quoting a heat pump install in Calhoun County does not need to size the system around a punishing weather history. 44 severe weather events were recorded in Calhoun County, West Virginia between 2015 and 2024. At that rate, severe weather is an occasional event here, not a standing operating condition, so the decisions that determine whether a heat pump performs well are local ones: soil conditions, duct layout, the age of the electrical service, and how carefully the unit is set. A system that underperforms in this county has a cause the contractor will find inside the house.

Ductwork laid down for a furnace carries different static pressure than a heat pump wants to push against, and in housing this old that gap is where installation budgets move. Half the homes in Calhoun County, West Virginia were built in 1975 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump here opens walls and measures what is actually there before the equipment choice means anything, because duct runs that served one system for generations carry bends, reductions, and joints the original builder sized for something else. The electrical panel gets the same look, since the draw a heat pump places on a service entrance is a real number a contractor has to verify, not assume.

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 exchanges heat with the outside air. Inside, the air handler mounts in a utility space, a closet, or an attic and moves conditioned air through the home. 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 between the two. A thermostat goes on an interior wall where it can read the living space and signal the system to run. The condensate drain line routes moisture pulled from the indoor air out of the house.

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 particular home.
