A contractor sizing and installing central AC here is working with a climate that delivers severe weather but not at a pace that dominates every system's life. 39 severe weather events were recorded in Oglethorpe County, Georgia between 2015 and 2024. At that rate, weather is a real variable but not the organizing fact of a system's wear. A poorly sized unit or a loose installation will fail here well before the weather explains it, and a good contractor quotes around those local specifics first.
Ductwork laid down for the equipment of an earlier era was not engineered to the load calculations a modern central AC unit requires, and that gap is what a contractor has to resolve before any installation quote means much. Half the homes in Oglethorpe County, Georgia were built in 1990 or earlier (2020-2024 ACS 5-year). That history shows up in the duct runs: undersized trunks, flex connections added later, supply registers that do not match current airflow demands. The electrical service in houses of that vintage carries its own questions. A contractor opening access panels in Oglethorpe County is finding out whether what the house already contains can carry the new system, or whether the ductwork itself is the first job.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad outside the house and holds the compressor and condenser coil, which are the core of the cooling side of the system. Inside, the air handler or furnace-and-evaporator-coil assembly mounts in a utility closet, basement, or attic and handles the indoor side of the exchange. These are the two main pieces a homeowner is buying.
A copper refrigerant line set runs between the outdoor and indoor units, connecting the two halves of the system through the wall or floor. The thermostat mounts on an interior wall and gives the homeowner control over when the system runs and what temperature it holds.
The drawing shows a typical layout, and a licensed contractor determines what fits the specific configuration of your home.

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.
Severe Weather Events in Oglethorpe County
Georgia's climate puts real strain on cooling equipment, and Oglethorpe County gets its share of weather that pushes systems hard. How often that happens here shapes what a central AC installation needs to handle over its working life.
