A contractor quoting a central AC installation in Charlton County is working out what the house actually demands, and the weather record is a small part of that calculation. 26 severe weather events were recorded in Charlton County, Georgia between 2015 and 2024. At that rate, severe weather is an event rather than a condition, and equipment here has not been carrying a storm load heavy enough to explain premature failure or drive unusual sizing decisions. What the installer is solving for instead is the age of the existing ductwork, how well the original system was matched to the structure, and whether the refrigerant lines were run correctly the first time.
Ductwork laid for an older system carries assumptions about airflow that a new central AC unit will test. Half the homes in Charlton County, Georgia were built in 1987 or earlier (2020-2024 ACS 5-year). A contractor installing new equipment in stock like this has to assess whether the existing runs, trunk lines, and returns will move air the way the new unit expects, or whether they will choke it. Electrical service matters too, since what a house of that era was wired for and what a modern unit draws are questions the panel answers or it does not. The ductwork is what takes time to evaluate, and what the quote turns on.
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, the two components that shed heat to the outside air. Inside, the air handler or furnace cabinet stands in a utility closet, basement, or attic and contains the evaporator coil along with the blower that moves air through the home.
The thermostat mounts on an interior wall where it reads the indoor temperature and tells the system when to run. A refrigerant line set, two insulated copper lines, runs between the outdoor unit and the air handler to connect those two halves of the system.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.

What HVAC Installation Looks Like in Charlton 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 in Charlton County
Weather extremes put real stress on HVAC equipment, and that stress shapes what a system needs to handle over its working life. Sizing and installation decisions for Charlton County homes follow from local conditions, not national averages.
