A contractor quoting Central AC in Wrangell has to start from what the house actually needs, not from what a cooling system would ordinarily be asked to do. Homes in Wrangell City and Borough, AK have essentially no cooling season — no month of the year is warm enough to call for it. The compressor in a unit installed here will sit idle through every month of the year, and long idle periods let refrigerant seals dry, contactors corrode, and drain lines go unnoticed until the first time anyone switches the system on. Sizing the unit correctly and sealing the refrigerant circuit well at installation are what determine whether the equipment works on that first call, because there is no accumulated runtime to surface a bad install before it matters.
Ductwork laid down for a wood or oil furnace was sized and routed for heat, and a central AC system has different demands on that same path. Whether what is already in the walls can carry a new system is the question a contractor has to answer before the equipment choice matters at all. Half the homes in Wrangell City and Borough, Alaska were built in 1976 or earlier (2020-2024 ACS 5-year). That tells you something about what a contractor is likely to find: duct runs designed around a different kind of system, and electrical service that may have been updated piecemeal rather than replaced wholesale. The ductwork assessment shapes the quote more than the unit selection does.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a pad beside the house and holds the compressor and condenser coil, the two components that do the heaviest work in the system. Inside, the air handler or furnace-mounted evaporator coil lives in a mechanical room, basement, or utility closet, and this is where cooled air enters the duct system.
A refrigerant line set runs between the indoor and outdoor units, typically along an exterior wall or through a chase, connecting the two sides of the system. The thermostat goes on an interior wall where it reads the house temperature and tells the system when to run.
The drawing shows the general layout of a central AC system, and a licensed contractor determines what applies to this particular house.

What the Installation Actually Looks Like
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.
