Takes about a minute. No obligation.
A contractor quoting a central AC installation in Oconee County has to size the system for local cooling demand, and the weather record is one part of that picture. 35 severe weather events were recorded in Oconee County, Georgia between 2015 and 2024. At that rate, severe weather is an event in this county, not a persistent operating condition, which means age and the quality of the original install explain far more about what happens to equipment here than anything in the storm record. A poorly sized or improperly commissioned system will underperform regardless of how calm the seasons are, and that is what a contractor confirms before equipment is ever specified.
Existing ductwork is the first thing a contractor has to evaluate on an installation job here, and in much of the county's housing that work was laid out for equipment generations removed from what runs today. Half the homes in Oconee County, Georgia were built in 1998 or earlier (2020-2024 ACS 5-year). Ducts designed around older load assumptions and different air-handler configurations may be too narrow, poorly routed, or sealed in ways that a modern system cannot use without correction. The electrical is a separate check, but it is the duct layout that most often changes the scope and the price of the job before a unit is ever ordered.
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 heaviest work in the system. Inside, the air handler mounts in a utility closet, attic, or basement and contains the blower fan and evaporator coil that pull heat out of your home's air.
A thermostat on an interior wall gives you control over the whole system and tells the air handler when to run. The refrigerant line set, a pair of insulated copper lines, runs between the air handler and the outdoor unit to connect the two sides of the system.
The drawing shows the general layout of a central AC system, and a licensed contractor determines exactly what applies to 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 Oconee County
Georgia's climate puts real stress on cooling equipment, and local weather patterns shape how hard a system has to work over its life. That load is a local fact, which is why it belongs on a page about AC installation in this area.
