A contractor quoting AC repair here has to set aside one of the usual questions first: how hard the system has been running the compressor. Homes in Nome Census Area, AK have essentially no cooling season — no month of the year is warm enough to call for it. A compressor that has never been called on to move heat out of the house has not worn its contacts, strained its capacitor, or cycled its refrigerant circuit through the stress that cooling loads produce. When a central AC unit fails in this area, the cause sits somewhere other than accumulated runtime. The contractor looks at seals that have sat dry, capacitors that have aged without cycling, and coils that may have drawn moisture through long idle periods.
Parts availability shapes how a central AC repair goes here more than the diagnosis does. Half the homes in Nome Census Area, Alaska were built in 1985 or earlier (2020-2024 ACS 5-year). A system running in stock that old is almost certain to have been installed or replaced at least once since the house was built, and the components it takes may be discontinued, scarce, or special-order. A contractor who opens the unit and finds a failed part still has to source it before the job is done, and in a remote area that wait is real.
The Parts of a Central AC a Contractor Checks During a Repair
The outdoor condenser unit sits outside the house, usually on a concrete pad beside or behind it, and it carries the compressor, the condenser coil, and the fan. These are the pieces a contractor reaches first, because a failed compressor or a clogged condenser coil will stop the whole system cold. When the outdoor unit is the problem, the house stops cooling entirely.
Inside the house, the air handler holds the evaporator coil and the blower. The air handler pulls warm air from the living space across that coil, and the blower pushes the cooled air back through the supply registers. The expansion valve and refrigerant lines run between the two units, and a fault in either can show up as weak cooling, ice on the coil, or pressure readings that tell a technician exactly where the failure sits.
The drawing shows a representative layout, and a licensed contractor determines what applies to this particular house and system.

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.
