Sizing central AC for a home in Franklin County starts with what the climate actually asks of equipment day to day, and storm history is a smaller part of that calculation than most homeowners expect. 68 severe weather events were recorded in Franklin County, Florida between 2015 and 2024. At that rate, severe weather is an event here rather than a standing condition, which means a contractor quoting an installation is focused on cooling load, duct layout, and the humidity the system has to pull out of the air. A unit undersized for the heat and moisture in this part of Florida will run harder and wear faster than anything the storm record explains.
Older ductwork was laid out for systems that moved air differently than current central AC units do, and whether it can carry a new load without being rerouted or replaced is the question that shapes the whole job. Half the homes in Franklin County, Florida were built in 1988 or earlier (2020-2024 ACS 5-year). A contractor running new equipment into a house from that era of the stock has to measure what the existing trunk lines will actually handle before the unit itself can be sized. Electrical service in houses of that vintage follows the same logic: the panel may need evaluation before a new system can run on it. The duct and electrical assessments are what drive the final scope.
What a Central AC System Includes
The indoor air handler sits inside the house, usually in a utility closet, attic, or garage, and it pulls warm air from the living space across a coil that does the cooling work. The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and the coil that releases heat outside.
A copper refrigerant line set runs between those two units, carrying refrigerant back and forth, and a condensate drain line runs from the indoor coil to carry away the moisture that collects during cooling. A programmable thermostat mounts on an interior wall and is the control point that tells the whole system when to run.
The drawing shows the general layout of a central AC system, and a licensed contractor determines what applies to your specific home.

What happens during an HVAC installation 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.
