Sizing a central AC system in Gordon County starts with the heat and humidity this area holds through summer, not with a storm-battered baseline that demands extra protective measures. 70 severe weather events were recorded in Gordon County, Georgia between 2015 and 2024. At that rate, severe weather is an occasional event rather than a constant pressure on equipment, which means a contractor quoting an installation here spends their attention on duct layout, load calculations, and how well the air handler fits the home. Getting those right is what determines whether a new system runs efficiently for years or underperforms from day one.
Ductwork laid down for an older system carries assumptions about airflow that a modern central AC unit does not share, and a contractor sizing new equipment here has to account for that before anything else gets priced. Half the homes in Gordon County, Georgia were built in 1987 or earlier (2020-2024 ACS 5-year). A house that old was built for a different load calculation, which means the existing duct runs, their diameters, and how they connect back to the air handler are the first things opened and checked. The electrical service gets the same look, since what a new unit draws has to be matched against what the panel was wired to supply. The unit itself gets selected after those answers are in.
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 two components that do the heaviest work in the system. Inside, the air handler mounts in a utility closet, basement, or attic and contains the evaporator coil and blower that move conditioned air through the home.
The thermostat goes on an interior wall where it can read the air temperature of the living space and signal the system when to run. A condensate drain line runs from the air handler to a nearby drain, and refrigerant lines connect the indoor and outdoor units along an exterior wall.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.

What happens when a contractor installs your system
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.
