A compressor that never runs still fails. Homes in Ketchikan Gateway Borough, AK have essentially no cooling season — no month of the year is warm enough to call for it. Seals dry out, contacts corrode, and refrigerant migrates into the compressor oil during long off-periods, so when a homeowner finally switches the unit on, the system that was never asked to cool anything is the one most likely to need repair. A contractor diagnosing a central AC fault here checks for dormancy damage before anything else, because the idle periods are where the failure started.
Half the homes in Ketchikan Gateway Borough, Alaska were built in 1977 or earlier (2020-2024 ACS 5-year). A house built that long ago has gone through at least one full equipment cycle, and the system a contractor opens today was installed into infrastructure that was already old at the time. On a repair call, what matters is whether the failed component inside that unit still has a supply chain. Condensing units and air handlers from discontinued product lines often share nothing with current parts catalogs, so a contractor pulling a failed capacitor, contactor, or control board has to source from specialty distributors rather than standard stock, and that search shapes both the repair timeline and what gets recommended next.
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 heat leaves the system. The indoor air handler or furnace-mounted evaporator coil sits inside, most often in a utility room, basement, or attic, and it is where the air actually gets cooled. Both are common starting points when a system stops performing.
The refrigerant lines are copper tubes that run between the two units, and a leak anywhere along them will pull the whole system down. The thermostat on the wall and the capacitors and contractors inside the outdoor unit are smaller pieces, but a failed capacitor or a bad thermostat signal is behind a large share of no-cool calls.
The drawing shows the typical layout of a central system, and a licensed contractor determines which components apply and need attention in your specific home.

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.
