A contractor diagnosing a heat pump repair in Lincoln County has to account for a compressor and reversing valve that have been working almost without pause. Homes in Lincoln County, WA run heat about ten months a year, from September through June. Refrigerant-side components take the hardest hit from that kind of sustained heating duty, because the system is moving heat into the house through cold outdoor air rather than dumping it outside in summer warmth. The reversing valve, the defrost controls, and the compressor bearings are where a technician looks first, not because the equipment is old, but because the load it carries is real and continuous.
Ductwork and wiring routed through a house built for something else wear differently than what a contractor finds in purpose-built installations. A refrigerant line tucked into a wall cavity that was never designed for it, or an electrical connection added when the original heat pump went in, can look fine from the outside and tell a different story once the unit is open. Half the homes in Lincoln County, Washington were built in 1972 or earlier (2020-2024 ACS 5-year). A contractor doing repair work here opens equipment knowing that what holds the system back is as likely to be a junction or a connection point elsewhere in the house as the component that stopped working.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit holds the compressor and the outdoor coil. The compressor is what moves the refrigerant through the system, and it is the piece a contractor reaches for when the heat pump runs but does not heat or cool. The outdoor coil works alongside it, and a damaged or fouled coil will send the same symptoms.
Inside the house, the air handler contains the indoor coil and the blower, which pulls air across the coil and pushes it through the home. The refrigerant lines connect the two units, and the reversing valve inside the outdoor cabinet is what allows the system to switch between heating and cooling. A fault in the valve shows up as the system stuck in one mode.
The drawing shows a general layout of the system, and a licensed contractor determines which components apply and what the work involves in your specific home.

Licensing and Legal Requirements in Lincoln County, Washington
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.
