A central AC compressor in San Juan County has almost no work on its record. Homes in San Juan County, WA have essentially no cooling season — no month of the year is warm enough to call for it. Contactor pitting, capacitor degradation, and refrigerant loss from cycling stress are not what a contractor finds here, because the compressor has barely cycled at all. A unit sitting idle season after season develops its own failure modes: seals dry, contacts corrode, and refrigerant can migrate through a system that never pressurizes. When a repair call comes in, the contractor is looking at dormancy damage and component age, not accumulated runtime wear.
Opened equipment tells a specific story here. Half the homes in San Juan County, Washington were built in 1988 or earlier (2020-2024 ACS 5-year). Housing of that vintage has had its central AC systems replaced, retrofitted, and patched across overlapping service cycles, which means the wear a contractor finds inside a unit reflects its own run history, not the house's build date. A capacitor that is failing, a contactor pitted by repeated cycling, a refrigerant circuit running low on charge for the second or third time: those conditions determine the repair, and none of them read off the exterior of the unit. The contractor opens it, measures what is there, and prices from that.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and it holds the compressor and condenser coil. These are where most repairs begin. A compressor that runs but cannot move refrigerant, or a condenser coil caked with debris, will stop the whole system cold.
Inside the house, the air handler holds the evaporator coil and the blower. The evaporator coil pulls heat out of the indoor air, and the blower pushes that air through the home. The refrigerant lines connecting the two units and the expansion valve that meters refrigerant flow are also points a contractor examines when the outdoor and indoor units both check out.
The drawing shows a typical central AC layout, and a licensed contractor determines which parts apply and what condition they are in for your specific home.

What HVAC repair looks like in San Juan 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 San Juan 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.
