Takes about a minute. No obligation.
A heat pump in this area works both sides of the cycle: heating through a long winter stretch, then cooling through summer, then heating again. Homes in Chelan County, WA run heat about ten months a year, from September through June. The reversing valve that shifts the system between those modes cycles far more often here than in areas with a short shoulder season, and a contractor diagnosing a fault checks that valve and the refrigerant circuit before looking elsewhere. Coil condition, refrigerant charge, and compressor amp draw all carry the signature of a system that rarely sits idle long enough to go unloaded.
Stock built for earlier generations of heating equipment has had those systems swapped out, upgraded, and replaced across the decades, and what is inside a heat pump in this county reflects that layered history. Half the homes in Chelan County, Washington were built in 1983 or earlier (2020-2024 ACS 5-year). When a contractor opens a unit here, the refrigerant circuit, the capacitors, and the contactor have each accumulated wear that tracks back through multiple ownership cycles. Parts for systems that have been in place through that span are sometimes discontinued, which changes the repair from a straightforward swap to a sourcing job before any labor begins.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad beside the house and holds the compressor and the condenser coil. The compressor is where most repair calls start. When it fails, the system stops moving heat altogether. The condenser coil wraps around it, and a bent or fouled coil forces the compressor to work harder than it should.
Inside the house, the air handler contains the evaporator coil and the blower. The evaporator coil can ice over or develop a refrigerant leak, and either problem shows up as weak heating or cooling at the vents. The reversing valve, which switches the system between heating and cooling mode, sits in the outdoor unit and is another piece a contractor checks when the system runs but delivers the wrong temperature.
The drawing shows a typical heat pump layout, and a licensed contractor determines which parts apply to your specific house and system.

Licensing Rules for HVAC Repair in Chelan 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.
Severe Weather Events in Chelan County
Extreme weather puts heat pumps under load at the worst possible times, and load is what surfaces faults that mild conditions hide. How often that pressure arrives in Chelan County shapes how hard the equipment here has to work and what repair needs look like.
