A heat pump working a Pembina County winter is running its compressor through sustained cold, not brief dips, and that is the circuit a contractor looks at first when a repair call comes in. Homes in Pembina County, ND run heat about nine months a year, from September through May. Cold outdoor air forces the refrigerant system to work harder to extract usable heat, which loads the compressor, the reversing valve, and the defrost controls in ways a mild-climate install never sees. By the time a homeowner notices a problem, those parts have already logged years of cold-weather cycling. A contractor pulling the unit apart here checks the compressor windings and the defrost board before anything else.
Ductwork in houses this old carries the record of every system that has run through it: debris, old seals, and wear that a heat pump repair brings to the surface fast. Half the homes in Pembina County, North Dakota were built in 1969 or earlier (2020-2024 ACS 5-year). A contractor opening a heat pump in stock like this routinely finds that the unit itself is the simpler part of the call. What slows the job is what the ductwork and the refrigerant circuit have accumulated, and whether the parts the system takes are still in supply.
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 two components that do the heaviest work. When a heat pump loses its ability to heat or cool, a contractor starts here. A failed compressor, a refrigerant leak at the coil, or a seized condenser fan motor will each stop the system in its own way.
The air handler lives inside, usually in a utility closet, basement, or attic, and moves conditioned air through the house. It contains the evaporator coil, the blower motor, and the expansion valve. The refrigerant line set connects the two units, and the reversing valve inside the outdoor cabinet is what lets the system switch between heating and cooling. A fault in any of these sends a contractor looking at that specific piece.

Severe Weather Events in Pembina County
