A heat pump in Jones County runs its heating cycle hard and long. Homes in Jones County, SD run heat about eight months a year, from October through May. The reversing valve switches modes at the start and end of every cycle, and a system that rarely goes idle accumulates that switching stress across hundreds of cold days. Refrigerant circuit wear follows the same pattern. A contractor diagnosing a fault here checks those components before anything else, because they carry the bulk of the seasonal load.
Stock this old was built for equipment that has since cycled through at least one full replacement generation. Half the homes in Jones County, South Dakota were built in 1973 or earlier (2020-2024 ACS 5-year). When a contractor opens a heat pump in a house from that era, the question is not whether the unit has wear but whether the specific capacitor, reversing valve, or control board it takes can still be sourced. If the part is obsolete, the repair scope changes before a quote can be written.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and condenser coil. The compressor is usually the first place a contractor looks when a heat pump stops moving heat reliably. A failed capacitor, a refrigerant leak at the coil, or a seized compressor each produce distinct symptoms that point a technician straight to this cabinet.
The air handler lives inside, most often in a utility closet or basement, and pushes conditioned air through the home. It contains the evaporator coil, the blower motor, and the reversing valve, which is the component that lets a heat pump both heat and cool. The expansion device and the refrigerant lines connecting the two units are also common targets when a contractor traces a pressure or airflow problem.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system and what each one needs.

Extreme weather puts heat pumps under load at the worst moments, and equipment that runs hard through harsh conditions takes on wear that shows up as repair needs later. How much stress local weather places on a system is a county-level question, not a national one.
