Takes about a minute. No obligation.
A short cooling season puts its entire load onto a narrow window of hard running. Homes in Franklin County, WA run cooling about two months a year, from July through August. The compressor starts and stops repeatedly through July and August, and the contactor takes every one of those cycles. When a unit fails, a contractor checks those components first, because the wear is concentrated rather than spread. A system that was undersized or poorly charged going in will show that at the contactor or the capacitor before it shows anywhere else.
Ductwork and electrical service in houses built around this period were already designed for central AC, so what a contractor finds behind the walls is rarely the source of a repair problem. Half the homes in Franklin County, Washington were built in 1997 or earlier (2020-2024 ACS 5-year). That matters because it narrows where the work actually lives: once the unit is open, the question becomes whether the failed component still has a supply chain. Some manufacturers have phased out parts for systems of this generation. A contractor who can identify the exact part before ordering saves the homeowner a wait and a second visit.
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 the condenser coil. The compressor is where most repair calls begin. When the system runs but puts out warm air, or shuts off before the house cools, a contractor goes to this unit first.
Inside the house, the air handler holds the evaporator coil and the blower fan, and it sits in a utility closet, attic, or basement depending on how the house was built. The refrigerant line set runs between the two units and connects the whole loop. A failing blower, a frozen evaporator coil, or a refrigerant leak in the line set each produce their own symptoms, and a contractor reads those symptoms to find which piece is the source.
The drawing shows the general layout of a central AC system, and a licensed contractor determines what applies to your specific house.

What HVAC Repair Looks Like in Franklin 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 Franklin County, Washington Requires for HVAC Repair Work
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.
