Sizing a heat pump for Clark County means accounting for what the heating season actually asks of it. Homes in Clark County, SD run heat about nine months a year, from September through May. As outdoor temperatures fall through those months, a heat pump's capacity drops, and a system sized too small shifts the load onto backup resistance heat to compensate. A contractor has to run a load calculation against the coldest stretches of that season, not against an average, because the gap between what the heat pump can deliver and what the house needs is where undersizing shows up on the utility bill and on the auxiliary heating elements first.
Ductwork in a house this old was designed around whatever was running when the house was built, and the gap between that system and a heat pump is where an installation either goes smoothly or gets complicated. Half the homes in Clark County, South Dakota were built in 1957 or earlier (2020-2024 ACS 5-year). A contractor putting in a heat pump has to trace those existing runs, check that they can move the air volume a heat pump requires, and confirm the electrical service can carry the load. If the duct layout falls short, the contractor re-routes or adds supply runs before the unit goes in.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners see first. It sits on a pad outside the house and holds the compressor and the outdoor coil, which together do the work of moving heat between inside and outside. The indoor air handler mounts in a mechanical room, closet, or attic space and pushes conditioned air through the home.
A refrigerant line set connects the two units, running through the wall or along the exterior to link the outdoor unit to the air handler. A thermostat goes on an interior wall and gives the homeowner control over the whole system.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the specifics of your house.
