A heat pump working a repair call here has already been carrying a load through cold that runs deep into spring. Homes in Edmunds County, SD run heat about nine months a year, from September through May. The compressor cycles hard through that stretch, and so does the reversing valve, which switches the refrigerant circuit between heating and cooling modes and takes the brunt of a long heating season in a way a straight cooling system never does. By the time a homeowner notices a fault, the compressor may have logged enough hard starts to show wear on the start capacitor and contactor as well. A contractor quoting a repair here checks those components alongside whatever failed first.

Ductwork and wiring installed for one era of equipment do not automatically signal where a heat pump repair will stall. The harder variable is parts. Half the homes in Edmunds County, South Dakota were built in 1967 or earlier (2020-2024 ACS 5-year). A system installed into housing that old has likely been through at least one retrofit, and the components it now runs on may come from a manufacturer line that has since been discontinued or narrowed. When a contractor opens the unit, what they find often determines whether the job closes in a single visit or turns into a sourcing problem that stretches the timeline.
The Parts of a Heat Pump a Contractor Checks First

The outdoor unit holds the compressor and condenser coil and sits on a pad outside the house. The compressor is where most failures start: when it labors, runs short cycles, or quits, the whole system stops moving heat. The condenser coil and the fan motor that pulls air across it are checked early for the same reason.
Inside, the air handler contains the evaporator coil and the blower motor, and it connects to the rest of the house through the supply and return openings. The reversing valve sits in the refrigerant line and is what lets a heat pump shift between heating and cooling. The expansion valve and the refrigerant lines that run between the two units round out what a contractor traces when the system is not performing.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components and conditions apply to your specific house.
