A heat pump here earns its hours on the heating side. Homes in Turner County, SD run heat about eight months a year, from October through May. The outdoor coil is working against cold air for the bulk of that run, which is where the reversing valve and compressor take their hardest loads. A contractor diagnosing a failed heat pump in this county checks those components first, because that is where the season lands. Refrigerant charge matters too: a pump running lean through a cold stretch loses capacity before it fails outright, and the homeowner often calls it a sizing problem.
Ductwork in a house this old was rerouted and repurposed as systems changed over the decades, but what drives a heat pump repair call is almost always inside the unit: a failing reversing valve, a compressor drawing the wrong current, contacts that have pitted past the point of reliable switching. Half the homes in Turner County, South Dakota were built in 1962 or earlier (2020-2024 ACS 5-year). A technician opening the unit in one of these houses traces the fault to the refrigerant circuit or the electrical components, and whether a replacement part is still in production for that equipment determines how the repair goes from there.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is where most repair calls begin. It holds the compressor, which moves refrigerant through the system, and the condenser coil, which releases or absorbs heat depending on the season. When either one fails, the whole system stops doing its job. The fan that draws air across that coil is another common point of failure.
Inside the house, the air handler contains the blower motor and the evaporator coil. The blower pushes conditioned air into the home, and the coil is where the refrigerant does its work on the indoor air. The reversing valve, which sits in the refrigerant line and tells the system which direction to run, is a part contractors check when the heat pump runs but heats or cools poorly.
The drawing shows a general layout of these components, and a licensed contractor determines what applies to your specific system and house.

Heat pumps work hardest when the weather outside is most demanding, and South Dakota's climate puts real pressure on equipment over time. Storm activity is part of that workload record, and it shapes how often repair needs come up in Turner County.
