A contractor quoting a central AC installation in Peach County works out what the house demands before anything else, and the local weather record is a smaller part of that calculation than homeowners often expect. 36 severe weather events were recorded in Peach County, Georgia between 2015 and 2024. At that rate, severe weather is an event here, not a condition, and a system that has struggled through recent summers is far more likely carrying the cost of its original sizing or the quality of its first install than any storm-related wear. That is what shapes the scope of new installation work: getting the load calculation and the equipment selection right, because those decisions outlast any single season.
Ductwork routed for equipment from a much earlier era of residential cooling does not always move the volume a modern central AC system needs, and Peach County's housing stock means that mismatch is a real possibility in a significant share of homes here. Half the homes in Peach County, Georgia were built in 1987 or earlier (2020-2024 ACS 5-year). A contractor installing a new system has to assess whether the existing duct runs, their sizing, and the electrical service can carry what is going in. If the ductwork falls short, the installation scope grows before the unit itself is ever priced.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, the hardware that does the system's heaviest work. Inside, the air handler or furnace-plus-coil assembly mounts in a mechanical room, basement, or attic and circulates conditioned air through the home.
The evaporator coil attaches directly to the air handler and is where the system pulls heat out of your indoor air. A refrigerant line set runs between the indoor and outdoor units, and a programmable thermostat mounts on a wall to give you control over the whole system.
The drawing shows the typical layout of these components, and a licensed contractor determines exactly what the installation involves for your specific home.

What the installation looks like from your end
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.
Severe Weather Events in Peach County
Weather puts a measurable load on cooling equipment, and that load varies by where you live. A central AC system sized and installed for what Peach County actually sees will run differently than one built to a generic spec.
