Sizing a central AC system for Brantley County starts with what the local climate actually demands, and that question is answered by contractors who know this area, not by a manufacturer's catalog. 45 severe weather events were recorded in Brantley County, Georgia between 2015 and 2024. At that rate, severe weather is an event here rather than a constant pressure, which means a system that is underperforming or failing has almost certainly been let down by the install itself or by years of deferred maintenance. A contractor quoting a new system in this county needs to get the load calculation and the duct work right from the start, because weather alone will not cover for what a bad install leaves behind.
Existing ductwork in a house this age was designed around equipment generations removed from what runs now, and whether it can carry a modern system is the question that shapes the whole job. Half the homes in Brantley County, Georgia were built in 1995 or earlier (2020-2024 ACS 5-year). A contractor installing central AC here has to assess those ducts and the electrical service before anything else gets priced, because both were built to different loads than what a new unit draws.
What Gets Installed With a New Central AC
The indoor air handler is the piece a homeowner notices first, sitting inside the home in a closet, attic, or utility room. It holds the evaporator coil and the blower that moves conditioned air through the house. Outside, the condenser unit houses the compressor and condenser coil, and it is the metal cabinet a contractor sets on a pad beside the house.
The thermostat mounts on an interior wall and serves as the control point for the whole system, telling the equipment when to run and when to stop. The refrigerant line set runs between the two main units, and the condensate drain line carries moisture away from the indoor coil to a drain point in the home.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the specifics of your home.

What happens on installation day
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 in Brantley County
Weather stress on a home accumulates through every heat event, cold snap, and storm a region sees over the years. A central AC system sized and installed for local conditions carries that load more reliably than one spec'd for somewhere else.
