Homes in Skagway Municipality, AK run heat in every month of the year. A heat pump running year-round cycles between heating and cooling mode, which puts repeated mechanical stress on the reversing valve and on the refrigerant circuit with every seasonal switch. Wear on those parts does not wait for a bad winter. A contractor diagnosing a repair call here checks the reversing valve first, then refrigerant charge and compressor draw, because those are the components the continuous cycle loads hardest.
Repair work on a heat pump here tends to resolve on parts availability before it resolves on labor. Half the homes in Skagway Municipality, Alaska were built in 1985 or earlier (2020-2024 ACS 5-year). A system running in housing of that vintage may have been retrofitted once or more since it was built, and each retrofit leaves its own layer inside the equipment. When a contractor opens the unit, what they find determines whether the repair is a stock order or a search, and that search can add time and cost the initial call gave no sign of.
The Parts of a Heat Pump a Contractor Checks First

The outdoor unit is usually where a contractor starts. It houses the compressor, which pumps refrigerant through the system, and the outdoor coil, which exchanges heat with the air outside. When either one fails, the system stops moving heat altogether. The refrigerant lines running between the outdoor unit and the house are checked alongside it, since a leak there shows up as lost performance at both ends.
Inside the house, the air handler holds the indoor coil and the blower fan. The coil absorbs or releases heat depending on the season, and the fan pushes conditioned air through your home. The reversing valve, which sits inside the outdoor unit, is what lets the system shift between heating and cooling. A contractor checks it when the system runs but delivers the wrong temperature.
The drawing shows a representative layout of these components, and a licensed contractor determines which parts apply to your specific system and home.
