Takes about a minute. No obligation.
A contractor diagnosing a central AC failure in Stevens County starts with the unit's mechanical condition, because demand is not what put it under strain. Homes in Stevens County, WA have essentially no cooling season — no month of the year is warm enough to call for it. A compressor that sat off through essentially every summer did not wear out through repeated starts and stops. If it failed, the contractor looks at seals, refrigerant charge, and electrical contacts first, the parts that degrade whether the system runs or not. Idle equipment still ages.
Half the homes in Stevens County, Washington were built in 1985 or earlier (2020-2024 ACS 5-year). A house that old was built around equipment that no longer exists in catalogs. When a contractor opens a central AC unit in stock like this, the question is whether the compressor, contactor, or control board it takes can still be sourced, and that answer changes the repair scope more than the fault itself does. A part that a newer system would get off a shelf becomes a search, a substitute, or a conversation about what comes next.
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 is where heat pulled from your home gets released. The indoor air handler or furnace sits inside, often in a basement, attic, or utility closet, and it pushes air across the evaporator coil, which is where the cooling actually happens. When something fails, the condenser, the air handler, and the evaporator coil are the pieces a contractor looks at first.
The refrigerant lines run between the indoor and outdoor units, carrying the refrigerant that makes cooling possible, and a leak or restriction in those lines shows up fast in how the system performs. The thermostat on your wall controls the whole sequence, and a contractor checks it alongside the electrical components at the air handler, including the capacitors and the contactor, which are small parts that fail more often than the larger equipment around them.
The drawing shows the general layout of a central AC system, and a licensed contractor will determine which components apply to your specific house and situation.

What HVAC Repair Looks Like in Stevens 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.
Licensing and Legal Requirements in Stevens 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 Stevens County
Extreme weather puts real hours on HVAC equipment. Stress from temperature swings, power fluctuations, and heavy atmospheric loads accelerates wear, and the pattern that plays out in Stevens County shapes what a local AC system is asked to endure.
