Takes about a minute. No obligation.
Central AC compressors wear through repeated starting and stopping, and the compressor in a Lane County home gets almost no opportunity to do either. Homes in Lane County, OR have essentially no cooling season — no month of the year is warm enough to call for it. A unit that sits idle every month of the year accumulates a different kind of stress than one working through a long summer: seals dry out, contacts corrode, and refrigerant can migrate into the compressor oil during long cold-off periods. When a contractor opens a call here, runtime hours are not what they are diagnosing against. The failure is more likely a seal, a contactor, or a refrigerant charge that drifted during years of disuse than a compressor that was simply run hard.
Half the homes in Lane County, Oregon were built in 1977 or earlier (2020-2024 ACS 5-year). A system running in a house that old has been serviced, patched, and partially replaced across multiple equipment cycles. When a contractor opens a unit here, the question that shapes the repair bill is whether the part it needs is still in production. Refrigerant fittings, capacitors, and control boards sized for older platforms go out of production quietly, and a house whose walls predate the equipment in them by a wide margin tends to have absorbed whatever was available at each replacement rather than a clean generational upgrade. That gap is where repair jobs stall.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along a side or rear wall, and it carries the compressor and the condenser coil. When refrigerant stops moving heat, or when the system runs but the air inside stays warm, those two components are where a contractor starts.
Inside the house, the air handler holds the evaporator coil and the blower. The evaporator coil sits in the airstream above the furnace or in a dedicated cabinet, and the blower pushes conditioned air through the ducts. The refrigerant line set ties the two units together, and the thermostat is what tells the whole system when to run.
The drawing shows a typical central AC layout, and a licensed contractor determines which components apply to your specific house and situation.

What HVAC Repair Looks Like in Lane 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.
