A contractor quoting a central AC install in Stephens County is working out what the house actually needs, not what the weather demands as a matter of course. 43 severe weather events were recorded in Stephens County, Georgia between 2015 and 2024. At that rate, severe weather is an event here, not a standing condition, which means a system's performance problems trace back to undersizing, poor installation, or age far more often than to storm load. A contractor who gets the load calculation right and installs the equipment cleanly has done the job the climate here asks for.
Ductwork laid down for an older system was sized and routed around that system's requirements. Half the homes in Stephens County, Georgia were built in 1983 or earlier (2020-2024 ACS 5-year). A contractor installing central AC in a house from that era has to assess whether the existing duct runs can carry what a new unit actually moves, and whether the electrical service supports the load, before any equipment goes on a truck. Those two questions settle more of the job's scope than the unit selection does.
What Gets Installed With a New Central AC
The outdoor unit sits on a concrete pad beside the house and holds the compressor and condenser coil. Inside, the air handler or furnace-and-coil combination occupies a utility closet, attic, or basement and moves conditioned air into the duct system. These are the two main pieces a contractor sets in place.
The thermostat goes on an interior wall where it reads the air temperature and signals the system to run or stop. A refrigerant line set runs between the outdoor unit and the indoor coil, and a condensate drain carries moisture pulled from the air to a floor drain or outside the home.
The drawing shows a typical layout, and a licensed contractor determines exactly what the installation involves in your house.

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 Stephens County
Weather in this part of Georgia puts real demands on cooling equipment, and those demands shape what a system needs to handle year after year. Sizing and installing central AC here is a local decision, and the record of weather events in Stephens County is part of that picture.
