Ductwork laid out for a heating-only system often lacks the return-air capacity and trunk sizing that central AC depends on, and what a contractor finds behind the walls here shapes the quote more than the equipment selection does. Half the homes in Kusilvak Census Area, Alaska were built in 1989 or earlier (2020-2024 ACS 5-year). That means a substantial share of the housing stock was built around duct configurations that were never planned for mechanical cooling. An installer has to assess whether existing runs can move the volume of air a central system demands before any unit goes in, and in many cases the ductwork needs alteration before the electrical question even comes up.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a pad beside the foundation, and holds the compressor and condenser coil. Inside, the air handler mounts in a utility space, basement, or attic and contains the evaporator coil and blower that move conditioned air through the home.
The refrigerant line set runs between the two units, typically along an exterior wall or through a chase, carrying the refrigerant that links them. A thermostat goes on an interior wall where it reads the home's temperature and signals the system to run.
The drawing shows a representative layout, and a licensed contractor determines exactly how each piece fits the configuration of your house.
