The compressor in a heat pump here carries its heaviest load in heating mode, pulling heat from outdoor air that drops well below freezing and doing it repeatedly across a long stretch of the calendar. Homes in Tripp County, SD run heat about eight months a year, from October through May. Reversing valves, defrost boards, and compressor windings take the most punishment on the heating side, and by the time the warm months arrive those parts have already been through their hardest work of the year. A contractor diagnosing a failed unit in Tripp County starts there rather than at the cooling components.
Ductwork in houses this old accumulates a repair history of its own: re-routed sections, patched joints, and dampers that no longer seat correctly. Half the homes in Tripp County, South Dakota were built in 1969 or earlier (2020-2024 ACS 5-year). When a contractor opens a heat pump here, what they find in the unit is only part of the picture. Leaks and restrictions in the duct runs can produce symptoms that point toward the equipment, and a repair scoped only around the unit may not hold. The ductwork gets measured and pressure-checked alongside the refrigerant circuit.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit holds the compressor and the condenser coil. It sits outside the house and carries most of the mechanical load, so when a heat pump stops heating or cooling the way it should, a contractor starts there. A failed compressor, a refrigerant leak at the coil, or a seized fan motor in that cabinet are among the first things they look for.
Inside the house, the air handler holds the evaporator coil and the blower that moves conditioned air through the home. Connecting the two units is the refrigerant line set, which runs through the wall and carries the working fluid between them. The reversing valve, which sits inside the outdoor unit, is what allows the system to switch between heating and cooling, and it is a common repair point when the system runs but delivers the wrong temperature.
The drawing shows a general layout of a heat pump system, and a licensed contractor determines which components apply and what condition they are in for any specific home.

Extreme weather puts heat pumps under sustained stress, and how hard a system works over its life is shaped by the conditions it runs in. Repair needs in Tripp County reflect that local reality.
