Takes about a minute. No obligation.
A contractor called out to repair a central AC unit here is not looking at a machine worn down by heavy summers. Homes in Skamania County, WA have essentially no cooling season — no month of the year is warm enough to call for it. Compressors that sit unused for years develop their own failure patterns: seals dry out, refrigerant migrates, and the first startup of a warm spell puts a sudden load on components that have had no recent cycling to keep them conditioned. The fault shows up on the first day a homeowner actually needs the system, which is rarely a convenient one to wait on a repair call.
Ductwork in a house this old was put in for a system that is no longer there. Half the homes in Skamania County, Washington were built in 1984 or earlier (2020-2024 ACS 5-year). That history matters most when a repair opens the unit: what the compressor, contactor, or refrigerant circuit turns out to be determines whether a contractor can source a direct replacement or has to work through what is still manufactured. Adapted and re-adapted systems accumulate substitutions that a repair has to account for one component at a time.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad against an exterior wall, and it is where the system sheds the heat it pulls from inside. When it fails, rooms stop cooling even though the air handler is still running. The compressor inside that cabinet is often the first component a contractor tests.
Inside the house, the air handler or furnace cabinet holds the evaporator coil, which is where the refrigerant does its work on the indoor air. The refrigerant lines connecting the two units, the contactor and capacitor inside the outdoor cabinet, and the thermostat that signals the whole system are all points a contractor works through when tracking down a fault.
The drawing shows a typical layout, and a licensed contractor determines what applies to the specific equipment and configuration in your home.

What the repair visit looks like
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 and Legal Requirements in Skamania 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.
