Central AC in Northwest Arctic Borough exists almost entirely outside its intended purpose. Homes in Northwest Arctic Borough, AK have essentially no cooling season — no month of the year is warm enough to call for it. A compressor installed here would sit idle through every month of the year, never cycling, never shedding heat, never doing the job it was built for. A contractor asked to quote central AC here is not sizing a system for a real load. They are answering a different question first: whether the installation serves any function at all in this climate.
Ductwork sized and routed for older equipment is what a contractor has to evaluate before anything else on a central AC installation here. Half the homes in Northwest Arctic Borough, Alaska were built in 1987 or earlier (2020-2024 ACS 5-year). That means a meaningful share of houses in this borough contain duct runs laid out around equipment with different static pressure and airflow requirements than a modern central system carries. The electrical service follows the same logic: panels in that generation of housing were not designed around the draw a current central AC unit puts on them. A contractor quoting a job here prices the box last, after measuring what the existing duct network and service panel will actually support.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and holds the compressor and condenser coil. Inside, the air handler or furnace-mounted evaporator coil lives in a utility space, basement, or closet, and is the indoor half of the system. Together these two units are what a homeowner is buying.
The refrigerant line set runs between the outdoor and indoor units, carrying refrigerant through a pair of insulated copper lines that pass through an exterior wall. A programmable thermostat goes on an interior wall and gives the homeowner control over the whole system. Both are part of a complete installation.
The drawing shows a typical layout, and a licensed contractor determines what the specifics of your house require.

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.
