A heat pump working a repair call in Bowman County has almost certainly been running hard right up to the day it failed. Homes in Bowman County, ND run heat about ten months a year, from September through June. The reversing valve cycles every time the system switches modes, and in this climate it switches often, through deep cold where the refrigerant circuit is under real strain. A contractor inspecting the outdoor unit here looks at that valve, the compressor contacts, and the coil surface before drawing any conclusion about what failed and what is simply worn.

Opened equipment in a house this age can belong to a generation of heat pumps whose parts are no longer manufactured, and what a contractor finds inside decides whether the repair is a parts swap or a dead end. Half the homes in Bowman County, North Dakota were built in 1972 or earlier (2020-2024 ACS 5-year). That span covers multiple equipment cycles, meaning the system running today was probably a replacement for something earlier, installed into a house whose layout and infrastructure were built around different assumptions. A refrigerant specification, a coil type, or a control board that predates current supply chains turns a straightforward repair into a sourcing problem the contractor has to price before committing to a scope.
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. These are the pieces a contractor reaches first when something is wrong. A failed compressor stops the system cold; a damaged or fouled coil means the unit cannot move heat the way it should.
Inside, the air handler sits in a utility space, closet, or attic and pushes conditioned air through the home. It contains the indoor coil and the blower motor, both of which a contractor inspects for damage, blockage, or wear. The refrigerant lines running between the two units and the reversing valve, which switches the system between heating and cooling, round out what gets examined.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components apply and what condition they are in at your specific home.
