A heat pump asked to cover heating through most of the year runs its compressor, reversing valve, and refrigerant circuit hard across nearly every season. Homes in Pacific County, WA run heat about ten months a year, from September through June. That load falls heaviest on the compressor, which cycles constantly in heating mode and must also handle the transition back into cooling. When a contractor opens a unit here, worn valve seats, refrigerant pressure that has drifted, and compressor draw that has crept up are the things they find first, not incidental faults but ones that reflect sustained runtime. Repair quotes that skip a refrigerant check or skip measuring compressor amperage are leaving the most loaded parts unexamined.
Half the homes in Pacific County, Washington were built in 1979 or earlier (2020-2024 ACS 5-year). In housing this old, the question a repair job answers is rarely simple. When a contractor opens the unit, what they find in the refrigerant circuit, the contactor, or the control board determines whether a standard part order closes the job or whether sourcing becomes a problem in itself. Heat pumps installed into stock of this vintage have often been replaced at least once already, and the generation of equipment now running may sit at the edge of what suppliers still stock. That parts picture, once the system is open, is what sets the repair bill.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad outside the house and holds the compressor and the condenser coil. The compressor is where most repair calls begin. It pressurizes the refrigerant, and when it labors or fails, the whole system stops moving heat. The condenser coil sheds or absorbs heat at that outdoor cabinet, and a damaged or dirty coil puts strain on everything around it.
Inside the house, the air handler contains the evaporator coil and the blower fan. The evaporator coil is the other side of the refrigerant loop, and a leak or blockage there shows up as weak heating, weak cooling, or ice on the coil. The blower pushes conditioned air through the house, and a failing motor or clogged wheel cuts airflow before anything else shows signs of trouble. The refrigerant lines and the reversing valve connect both sides of the system, and the reversing valve is what lets a heat pump run in both directions, making it a specific point a contractor checks when the system heats but will not cool, or the reverse.
The drawing shows a typical heat pump layout, and a licensed contractor determines what applies to the specific equipment and configuration in your home.

Washington requires contractor registration rather than an HVAC licence: every contractor must register with the Department of Labor and Industries, and advertising, bidding or working as a contractor without that registration is a gross misdemeanour.
