Step 1 of 3: Equipment

A contractor quoting a central AC installation in Fannin County has to work out what the existing equipment has actually been through before they can size a replacement correctly. 70 severe weather events were recorded in Fannin County, Georgia between 2015 and 2024. At roughly that pace, most systems here have spent their lives running against ordinary seasonal load rather than chronic storm stress. Age, installation quality, and whether the original unit was sized for the house explain most of what a contractor finds when a system fails here. The refrigerant lines, the coil condition, and the electrical connections at the air handler tell the story, and the weather does not change that story much.

Ductwork sized for a previous generation of equipment does not automatically carry a new central AC system. A contractor installing in Fannin County has to open and measure what is already in the house before anything else can be priced, because the ducts may have been laid for a smaller or differently configured unit than the one going in. Half the homes in Fannin County, Georgia were built in 1996 or earlier (2020-2024 ACS 5-year). Stock from that era was built around equipment that has since been replaced, often more than once, and each swap left the ductwork as-is. What a contractor finds in those runs determines whether the installation is straightforward or whether the ductwork gets reworked alongside the new unit.

What Gets Installed With a New Central AC

The outdoor unit, called the condenser, sits on a concrete pad outside the house and holds the compressor and condenser coil. Inside, the air handler or furnace-mounted evaporator coil lives in a utility closet, attic, or basement and is the indoor half of the system. Together these two units are what a Central AC installation puts in place.

The refrigerant line set runs between the two units, connecting the indoor coil to the outdoor condenser through a pair of insulated copper lines. A thermostat, mounted on an interior wall, is also part of what a contractor installs, giving the homeowner control over when the system runs and at what temperature.

The drawing shows the general layout of a Central AC system, and a licensed contractor determines exactly how each piece applies to your house.
