A heat pump doing repair work in Hanson County is almost always a machine that has been running its heating cycle far longer than its cooling cycle, which tells a contractor where to look first. Homes in Hanson County, SD run heat about eight months a year, from October through May. Compressor wear from that load shows up as reduced capacity on the coldest days, often long after the fault has been building. The reversing valve takes a cycling stress every time the system shifts between modes, and in a county where heating dominates, that valve logs far more transitions in one direction. Refrigerant charge and the condition of the outdoor coil matter here too, because a coil that is not moving heat efficiently in cold air forces the compressor to work harder to hold temperature.
Ductwork sized and routed for the heating equipment that originally served these houses shapes what a contractor opens today. Half the homes in Hanson County, South Dakota were built in 1956 or earlier (2020-2024 ACS 5-year). A heat pump installed into stock of this vintage was likely retrofitted into a house that had never run one before, which means the system inside it may draw on a parts supply that has thinned out or disappeared entirely. When a repair comes down to a failed component, the question is whether that part is still made, and in houses this old, the answer changes both what the contractor orders and how long the job takes.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize, and it is usually where a contractor starts. It houses the compressor and the condenser coil. The compressor is the heart of the system, and when it fails the unit runs but moves no heat. A refrigerant leak shows up here too, often as ice on the coil or a unit that runs constantly without result.
Inside the house, the air handler holds the evaporator coil and the blower motor. The coil transfers heat to or from the indoor air, and a dirty or cracked coil is a common source of poor performance. The blower motor pushes conditioned air through the house, and a failing one shows up as weak airflow or unusual noise. The two units are tied together by refrigerant lines and a set of electrical controls, including the reversing valve that lets the system heat in winter and cool in summer. That valve is a frequent point of inspection when the system works in one mode but not the other.
The drawing shows a typical heat pump layout, and a licensed contractor determines which components apply and what each one needs in your specific home.

Extreme weather puts real strain on heat pump systems, which work hardest precisely when outdoor conditions are worst. How much of that strain a unit accumulates over time is a local question, and the record below reflects what the equipment in this county has been up against.
