A contractor quoting a heat pump installation in Mingo County has to account for what the local climate routinely asks of a system, because the load here is not occasional. 85 severe weather events were recorded in Mingo County, West Virginia between 2015 and 2024. At that rate, severe weather is a standing condition of equipment life in this area, and a contractor who treats it as an edge case will undersize refrigerant capacity or overlook the durability specs that matter here. Matching the install to actual local demand is the work.

Ductwork laid down for older heating systems carries assumptions about static pressure and airflow that a heat pump does not share. Half the homes in Mingo County, West Virginia were built in 1982 or earlier (2020-2024 ACS 5-year). A contractor sizing a heat pump here has to assess whether the existing trunk lines and branch runs can actually move the volume the new equipment needs, and in many houses they find sections that cannot. The electrical service is a separate question, but the duct layout is where the installation either fits or requires rework before the unit goes in.

What Gets Installed With a New Heat Pump

The outdoor unit sits on a pad beside the house and holds the compressor and the condenser coil. Inside, an air handler mounts in a utility closet, basement, or attic and moves conditioned air through the home. A refrigerant line set runs between the two, connecting the outdoor and indoor sides into a single system.

A thermostat goes on an interior wall and gives the homeowner control over temperature and scheduling. Some installations also include a supplemental electric resistance coil inside the air handler, which a contractor sizes and positions based on the house's heating load.

The drawing shows a general layout of these components, and a licensed contractor determines exactly what applies to this particular house.
