Takes about a minute. No obligation.
A contractor quoting AC repair here starts from a different baseline than in a county where the compressor runs hard from June through August. Homes in Wasco County, OR have essentially no cooling season — no month of the year is warm enough to call for it. That means the contactor has rarely cycled, the condenser fan has rarely spun up, and a compressor fault points toward a manufacturing defect, a refrigerant problem, or years of sitting idle rather than toward wear from heavy use. Long idle periods let corrosion take hold on electrical contacts and let refrigerant migrate in ways that only show up the first time a homeowner switches the unit on during a rare hot spell.
Half the homes in Wasco County, Oregon were built in 1973 or earlier (2020-2024 ACS 5-year). When a system in housing like this fails, what a contractor finds inside the unit shapes the repair more than the failure itself. Worn compressor valves or a cracked heat exchanger may call for parts that current distributors no longer stock, which turns a straightforward repair into a sourcing problem. That is not a possibility to guard against here; it is a condition the contractor prices around from the start.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and it carries the compressor and condenser coil. These are the parts a contractor reaches first when a system stops cooling or runs but does nothing useful. A failed compressor, a clogged or damaged coil, or a refrigerant problem will show up here.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower. The evaporator coil is where a frozen coil, a refrigerant leak, or a drainage issue becomes visible. The blower motor and the capacitor that starts it are also inside this cabinet and are common points of failure when airflow drops or the system won't start.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific home and system.

What HVAC Repair Looks Like in Wasco 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.
