Sizing a heat pump for this county means knowing exactly how cold it gets from November through March, because capacity drops as outdoor temperatures fall and the system leans on backup heat to close the gap. Homes in Dillon County, SC run heat about five months a year, from November through March. A contractor quoting a new install here has to establish the coldest design conditions the unit will face, not just the average load across the season. An undersized heat pump in this climate does not fail abruptly; the resistance strips carry what the refrigerant cycle cannot, and the homeowner pays for that quietly until the compressor wears down from cycling at its limits.
Ductwork sized and routed for an older system answers to a different set of airflow demands than a heat pump puts on it. Half the homes in Dillon County, South Carolina were built in 1984 or earlier (2020-2024 ACS 5-year). A contractor pricing a heat pump installation here has to assess what the existing duct runs will actually carry before the equipment selection means anything. If the ducts are undersized or laid out in a way that chokes return air, the unit will underperform regardless of its specs, and correcting that becomes part of the job. The electrical service gets the same look, since a heat pump draws differently than whatever the house was built around.
What Gets Installed With a New Heat Pump
The outdoor unit sits on a concrete pad beside the house and holds the compressor and the main coil. The indoor air handler mounts inside, most often in a utility closet, attic, or crawlspace, and it is the piece that moves conditioned air through the home. Together these two units are what a heat pump installation puts in place.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two through the wall or floor. A thermostat mounts on an interior wall and gives the homeowner control over the whole system. The disconnect box goes on the exterior wall next to the outdoor unit and lets a contractor cut power to that unit safely.
The drawing shows a typical layout, and a licensed contractor determines what fits the specifics of this house.
