Takes about a minute. No obligation.
A heat pump running nearly year-round puts steady work on its refrigerant circuit, its reversing valve, and the defrost controls that keep it alive in deep cold. Homes in Eddy County, ND run heat about nine months a year, from September through May. The defrost cycle alone runs repeatedly through those months, and each cycle stresses the reversing valve. A contractor quoting a repair here checks that valve and the refrigerant charge before anything else, because both degrade under sustained heating-season load in ways that mimic other faults. A misread there sends the job in the wrong direction.
Parts availability is the variable that shapes a heat pump repair job in Eddy County more than anything a homeowner sees from the outside. Half the homes in Eddy County, North Dakota were built in 1966 or earlier (2020-2024 ACS 5-year). A house that old has likely had its mechanical systems replaced or adapted more than once, and each change leaves the current equipment further from the original build. When a contractor opens a heat pump in stock like this, what determines the repair scope is whether the components that unit actually takes are still in production. Some are. Some require sourcing from specialized suppliers, and that changes both the timeline and what the contractor recommends.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad beside the house and holds the compressor, which is the part that does the heaviest work and is often where a repair begins. The coil wrapped around the inside of that cabinet either pulls heat from the outside air or rejects it, depending on the season. When either piece is off, the whole system feels it.
Inside the house, the air handler mounts in a utility space or closet and moves conditioned air through the home. The reversing valve sits within the refrigerant circuit and is what lets the system run in both directions. The expansion valve, also inside the refrigerant loop, is a smaller but precise component that a contractor will check when temperatures at the registers do not match what the thermostat is calling for.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which parts apply and what work is needed in your particular home.
