A contractor quoting a central AC installation in Franklin County starts with the house: its square footage, its insulation, how the ductwork is laid out. Those factors drive the sizing decision far more than the weather does. 43 severe weather events were recorded in Franklin County, Georgia between 2015 and 2024. At that rate, severe weather is an event in this county, not a condition systems are built around. Age of the existing equipment, how well the original install was done, and how consistently the system was serviced are what explain most of what contractors find here when a system has failed.
Ductwork that predates modern central air was laid out for a different job, and whether it can carry a new system is what a central AC installation in Franklin County actually turns on. Half the homes in Franklin County, Georgia were built in 1989 or earlier (2020-2024 ACS 5-year). A house built in that period was designed around heating, and the duct runs, return placements, and trunk sizing that made sense then do not always match what a new cooling unit requires. The electrical service is the second check: panel capacity and circuit availability have to be confirmed before anything gets quoted. The equipment selection comes after those answers, not before.
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 two components that do the heaviest work in the system. Inside, the air handler mounts in a closet, attic, or utility room and contains the evaporator coil along with the blower that moves air through the home.
A condensate drain line runs from the air handler to carry away the moisture the coil pulls from indoor air, and a refrigerant line set connects the indoor and outdoor units through a small penetration in the wall. The thermostat goes on an interior wall and gives the homeowner direct control over the whole system.
The drawing shows a typical layout, and a licensed contractor determines exactly how these components are positioned and connected in your specific home.

What HVAC Installation Looks Like in Franklin County
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 Franklin County
Georgia's climate puts real pressure on cooling equipment, and Franklin County gets its share of what that pressure looks like. How hard a system has to work, and how long it holds up, is a local question.
