Ductwork in a house carries whatever system is running in it now, and the older the house, the longer that system has been cycling through an Alaskan heating and cooling load. Half the homes in North Slope Borough, Alaska were built in 1984 or earlier (2020-2024 ACS 5-year). A contractor opening a central AC unit in stock that old is often working out whether the parts it needs are still in production, not just what failed. Compressor components, capacitors, and refrigerant-side hardware for systems that have been running since before recent equipment generations can sit at the edge of availability. That is where the repair scope gets uncertain, and it is what a quote here has to account for before a price is real.
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 gets shed to the outside air. The compressor lives inside that cabinet and is one of the first things a contractor looks at when a system stops cooling. A failed compressor, a refrigerant leak at those fittings, or a seized condenser fan motor each produce their own symptoms.
Inside the house, the air handler or furnace cabinet holds the evaporator coil, the blower motor, and the filter. The evaporator coil is a common source of trouble when airflow drops or the unit starts freezing over. The refrigerant lines connecting the two cabinets, and the thermostat signaling the whole system, round out what a contractor traces when something is off.
The drawing shows a typical central AC layout, and a licensed contractor determines which components apply and what condition they are in for your specific home.

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.
