Takes about a minute. No obligation.
A central AC compressor in Douglas County runs hard and then stops. Homes in Douglas County, WA run cooling about two months a year, from July through August. The contactor and condenser fan carry the same concentrated load, cycling through heat and dust across a short but complete season. When a compressor fails, a contractor checks those components for wear patterns that match a full seasonal push, not a partial one. Bearings, capacitors, and contactor pitting tend to tell the story plainly.
Central AC systems in housing stock this old do not fail in uniform ways. Half the homes in Douglas County, Washington were built in 1988 or earlier (2020-2024 ACS 5-year). A contractor who opens a unit here may find a capacitor that has been running hot for seasons, a contactor worn thin, or refrigerant lines showing corrosion at the fittings. What that inspection turns up drives the repair scope, and parts availability for some equipment of this age is a live question before any work is priced.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it carries the compressor and condenser coil. These are the pieces a contractor reaches first when the system stops cooling. A failed compressor, a refrigerant leak at the coil, or a seized condenser fan motor will all show up here.
Inside the house, the air handler holds the evaporator coil and the blower, sitting in a closet, attic, or mechanical room where it connects to the supply and return ducts. The thermostat on the wall ties the two halves together, and a contractor will check its wiring and calibration alongside the electrical components at both units.
The drawing shows a typical central AC layout, and a licensed contractor determines which parts apply to this particular house and installation.

What HVAC Repair Looks Like in Douglas County
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.
What Douglas County and Washington Require for HVAC Repair
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.
