Sizing a heat pump for Kershaw County starts with understanding how long the heating load actually runs. Homes in Kershaw County, SC run heat about five months a year, from November through March. As temperatures fall through December and January, a heat pump's output drops while the house's demand rises, and a system undersized at installation has nowhere to hide that gap. A contractor working a quote here has to calculate where that crossover point lands and whether supplemental heat is wired to cover it. Ductwork condition and the service panel both factor in before any equipment is specified.
Ductwork designed around a furnace and central air setup carries air at a different pressure and volume than a heat pump demands. A contractor quoting a heat pump installation here has to assess what the existing duct system will actually do under the new load before the equipment choice means anything. Half the homes in Kershaw County, South Carolina were built in 1993 or earlier (2020-2024 ACS 5-year). That share of the housing stock was built when resistance heat or gas furnaces were the default, and the duct geometry that made sense then can restrict airflow enough to cut a heat pump's efficiency or shorten its service life. Electrical service is its own question too, since a heat pump's draw differs from what many of those panels were originally sized to handle.
What a Heat Pump Installation Puts in Your Home
The outdoor unit is the piece most homeowners see first. It sits on a pad beside the house and holds the compressor and the outdoor coil, which are the components that do the heaviest work of moving heat between the refrigerant and the outside air. The indoor air handler mounts in a utility space, attic, or closet and pushes conditioned air through the home.
A refrigerant line set runs between the two units, carrying refrigerant back and forth through insulated copper tubing. The thermostat goes on an interior wall and serves as the control point for the whole system. Some installations also include a supplemental electric heat strip inside the air handler, which a contractor sizes and positions during the install.
The drawing beside this text shows the general layout of these components, and a licensed contractor determines exactly how each one applies to your house.
