Refrigerant lines, compressor internals, and electrical connections all degrade differently when they spend years in subarctic cold, and a heat pump repair in North Slope Borough gets decided by what those components look like once the casing is off. Half the homes in North Slope Borough, Alaska were built in 1984 or earlier (2020-2024 ACS 5-year). Stock of that vintage was built for equipment that ran on refrigerants and parts no longer in standard production, so a contractor opening a unit here has to determine whether a replacement part is still made before a repair scope can be set. A system that looks serviceable from the outside can have seals and motor windings that the cold has worked on for a long time.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is where most repair calls begin. It sits outside the house and holds the compressor, which pressurizes the refrigerant, and the fan, which moves air across the coil. When the system stops heating or cooling, a contractor starts here, checking whether the compressor is running, whether the fan is spinning, and whether the coil is clear.
Inside the house, the air handler holds the indoor coil and the blower fan that pushes conditioned air through the home. The refrigerant lines run between the two units, and the reversing valve inside the system is what lets a heat pump work in both directions. A fault in any of these parts shows up as weak airflow, incorrect temperatures, or a unit that runs but does nothing.
The drawing shows a typical heat pump layout, and a licensed contractor determines which parts apply to the specific system in your home.
