A contractor quoting central AC here has to be direct about what the equipment will actually do. Homes in Copper River Census Area, AK have essentially no cooling season — no month of the year is warm enough to call for it. The compressor will not cycle through summer heat waves, the condenser fan will not log hundreds of hours pushing heat out of the house, and the contactor will not wear from repeated starts across a long season. What a licensed installer has to establish before any equipment is specified is whether the project serves a genuine purpose, because a system sized to a cooling load that does not exist produces a quote built on the wrong foundation.
Ductwork built for a furnace and nothing else tends to run where heat delivery was the only goal, with trunk lines, branch diameters, and return paths that a central AC system will stress in ways the original design never anticipated. Half the homes in Copper River Census Area, Alaska were built in 1985 or earlier (2020-2024 ACS 5-year). That depth of housing stock means a contractor sizing a new central AC unit here has to map what is actually in the walls and ceiling before a load calculation means anything, because ductwork that cannot move conditioned air to every room turns a correctly sized unit into an undersized one. The electrical service gets checked for the same reason: panels in houses of this era were built around a load that did not include central cooling.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a pad outside the house and holds the compressor and condenser coil, the hardware that does the heaviest work in the system. Inside, the air handler or furnace-mounted evaporator coil lives in a utility space, basement, or closet, where it connects to the home's air supply.
A refrigerant line set runs between the two units, linking the indoor and outdoor sides through the walls or along the exterior. The thermostat goes on an interior wall where it reads the living space temperature and tells the system when to run.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific house.

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.
