Sizing central AC in Douglas County starts with what the equipment will actually run against, and the weather record here is part of that answer. 141 severe weather events were recorded in Douglas County, Georgia between 2015 and 2024. At that rate, severe weather is a routine operating condition, not an occasional one, and a contractor who ignores it when selecting equipment and specifying the install is quoting for a different place. Refrigerant line routing, electrical protection, and unit placement all get priced and decided with that load in mind.
Existing ductwork is what a central AC installation in Douglas County turns on. Half the homes in Douglas County, Georgia were built in 1996 or earlier (2020-2024 ACS 5-year). Houses from that era were built around equipment with different airflow demands than current systems carry, and the ducts that served those systems may not move air the way a new unit needs. A contractor has to assess the duct runs and the electrical service before any other part of the job makes sense, because those two things decide the scope more than the equipment selection does.
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 mounts in a utility closet, basement, or attic and contains the evaporator coil and the blower that moves conditioned air through the home.
The thermostat goes on an interior wall where it reads the home's air temperature and tells the system when to run. A condensate drain line runs from the air handler to a nearby drain, carrying away the moisture the evaporator coil pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines what applies to your house specifically.

What the installation looks like in Douglas 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 Douglas County
Weather stress is real load on cooling equipment, and Douglas County's climate is what sizes that load. A central AC system installed here has to handle whatever this area delivers, which is why local weather history belongs on a page about installation.
