Takes about a minute. No obligation.
A compressor that sits dormant through fall, winter, and spring can develop contactor wear, refrigerant seepage, or capacitor degradation without giving any sign until the homeowner flips the thermostat in July. Homes in Asotin County, WA run cooling about two months a year, from July through August. A contractor diagnosing a failed startup on that first hot call checks the electrical side first, because those components degrade on the shelf as much as under load. The condenser fan and the contactor are the parts most likely to have quietly crossed a threshold during the off-season, not from overwork but from inactivity and temperature swings.
Ductwork in a house gets modified across decades as systems come and go, and the coils, contactors, and refrigerant lines a contractor finds once the unit is open reflect that layered history. Half the homes in Asotin County, Washington were built in 1976 or earlier (2020-2024 ACS 5-year). That puts a repair contractor in a position where parts availability is as live a question as the diagnosis itself: components from successive equipment generations sit inside the same cabinet, and not every part that fits an older adapted system still ships. What the opened unit contains determines whether the repair is a same-week fix or a sourcing problem.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually beside the foundation, and houses the compressor and condenser coil. These are the parts a contractor reaches first when the system is not cooling. A failed compressor, a refrigerant leak at the coil, or a seized condenser fan motor are common reasons a central AC stops doing its job.
Inside, the air handler holds the evaporator coil and the blower. The air handler typically lives in a closet, attic, or utility room. Problems here show up as warm air from the vents, ice forming on the coil, or a blower that runs but moves little air. The refrigerant line set connects the two units, and a leak anywhere along it affects both.
The drawing shows a representative layout, and a licensed contractor determines which components apply to your specific system and situation.

What Happens When a Contractor Comes Out
Split-system central air conditioners rated below 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners rated at or above 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners manufactured between January 1, 2015 and December 31, 2022 had to meet 13 SEER, the metric that preceded SEER2.
Single-package central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Space-constrained central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 11.7 SEER2.
Federal efficiency standards for split-system central air conditioners and heat pumps are set on each certified combination of outdoor unit and indoor coil rather than on the outdoor unit alone.
Residential and light commercial air conditioning and heat pump systems assembled in the field, including mini-splits and unitary systems, may not be installed on or after January 1, 2025 using a refrigerant with a global warming potential above 700.
A field-assembled system whose specified components were all manufactured or imported before January 1, 2025 carries no installation compliance date under the refrigerant restrictions and may still be installed.
Licensing Rules for HVAC Repair in Asotin 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.
Weather Stress on HVAC Equipment in Asotin County
Extreme weather puts mechanical load on cooling systems, and that load accumulates. A contractor servicing central AC in Asotin County is working on equipment shaped by local conditions, not generic ones.
