Sizing a heat pump for this county means solving a problem that gets harder as outdoor temperatures drop: a heat pump's capacity falls with the cold, and Edmunds County winters are serious. Homes in Edmunds County, SD run heat about nine months a year, from September through May. A contractor quoting here has to establish at what outdoor temperature the heat pump's output falls below what the house actually needs, and then size the backup heating element against that gap. Undersizing the backup means the compressor strains through the coldest weeks while the house still falls short of setpoint.
Ductwork in this county's housing stock carries a long service history, and what a contractor finds behind the walls often reflects decisions made for equipment that has been gone for decades. Half the homes in Edmunds County, South Dakota were built in 1967 or earlier (2020-2024 ACS 5-year). When a heat pump goes in, the existing duct runs get tested against what the new unit actually requires, and the layout of those runs, not the equipment itself, is where the installation job either straightens out or gets complicated. Panels get checked for the same reason.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners notice first. It sits on a concrete pad or wall brackets outside the house and holds the compressor and the outdoor coil. Inside, the air handler mounts in a utility closet, basement, or attic and moves conditioned air through the home.
A refrigerant line set connects the two units, running through the wall or along the exterior to carry refrigerant between them. A thermostat goes on an interior wall and gives the homeowner control over the whole system. Some installs also include a supplemental electric resistance element inside the air handler for the coldest stretches.
The drawing shows a representative layout, and a licensed contractor determines what fits and what is needed in your specific home.
