A heat pump running through a North Dakota winter is doing its hardest work when outdoor temperatures drop furthest from the indoor setpoint, and the compressor and reversing valve carry that load every cycle. Homes in Ramsey County, ND run heat about nine months a year, from September through May. By the time a repair call comes in, the compressor has been pulling against cold outdoor air across the bulk of the calendar year, not the mild shoulder weeks. A contractor diagnosing a failed heat pump here checks refrigerant charge and valve function before looking at electrical components, because those are the parts that accumulate stress under sustained low-temperature operation. Wear patterns in the compressor windings tell a lot about whether a repair buys meaningful time or whether the next cold stretch will produce the same call.

Half the homes in Ramsey County, North Dakota were built in 1976 or earlier (2020-2024 ACS 5-year). A heat pump running in a house that old has likely been through at least one set of components already, and what a contractor finds when the unit is opened depends heavily on what previous repairs used. If the system takes a part that has gone out of production, the job changes: a contractor sourcing a substitute has to confirm it fits the existing refrigerant circuit and control wiring without requiring a broader teardown. That is the repair question this stock keeps raising.
The Parts of a Heat Pump a Contractor Checks First

The outdoor unit sits on a pad beside the house and holds the compressor and the outdoor coil. Those two components do the heaviest work, so when a heat pump stops heating or cooling properly, a contractor starts there. A failed compressor or a damaged coil will show itself fast.
Inside the house, the air handler moves conditioned air through the home and holds the indoor coil and the blower motor. The reversing valve, which sits in the refrigerant line and tells the system which direction to run, is another piece a contractor checks when the system is stuck in one mode. The refrigerant lines that connect the two units can develop leaks, and the expansion valve that controls refrigerant flow is a common source of trouble as well.
The drawing shows a typical heat pump layout, and a licensed contractor will determine which parts apply to your specific system and situation.
