A heat pump in this area runs its compressor hard through a long, cold heating season, and cold is where heat pumps work hardest. Homes in Logan County, ND run heat about nine months a year, from September through May. At low outdoor temperatures, the refrigerant circuit strains to extract enough heat from the air, which puts repeated stress on the compressor and the reversing valve across every cycle of every heating month. By the time a homeowner calls for a repair, those parts have logged serious hours. A contractor diagnosing a refrigerant fault or a compressor failure here has to weigh that accumulated load before deciding whether a component failed prematurely or simply reached the end of what it had left.

Ductwork in a house this old carries the record of every system that has ever run through it: patches, reroutes, and seals added whenever the equipment changed. Half the homes in Logan County, North Dakota were built in 1967 or earlier (2020-2024 ACS 5-year). A contractor opening a heat pump here will work out what is wrong with the unit, but what determines the scope and the bill is often the duct runs feeding it, which may have been adapted more than once since the house was framed. Gaps, collapsed flex, and degraded seals in that ductwork can produce symptoms that look like a refrigerant or compressor problem until the system is traced end to end.
The Parts of a Heat Pump a Contractor Checks First

The outdoor unit sits outside the house and holds the compressor and the condenser coil. The compressor is the part a contractor reaches for first when the system stops moving heat altogether. A failed condenser coil, by contrast, tends to show up as ice buildup or weak output.
Inside the house, the air handler holds the evaporator coil and the blower motor. The evaporator coil is where refrigerant does its work on the indoor air, and a slow refrigerant leak often announces itself here. The blower motor and the reversing valve, which tells the system which direction to run, are the other two pieces a contractor checks when the complaint is that the system heats when it should cool, or does nothing at all.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which of these parts applies to the situation in your house.
