Sizing central AC for a house in Dougherty County means accounting for what the equipment will run against, year after year, before a single component wears. 125 severe weather events were recorded in Dougherty County, Georgia between 2015 and 2024. At that rate, severe weather is part of the normal operating environment, and a contractor who ignores it when selecting equipment capacity and specifying installation tolerances is setting a system up to underperform before it ages. Refrigerant line routing, electrical protection, and unit placement all carry different weight here than they do in quieter counties.
Ductwork laid down for an older system carries assumptions about static pressure, trunk sizing, and return placement that a modern central AC unit was not designed around. Half the homes in Dougherty County, Georgia were built in 1975 or earlier (2020-2024 ACS 5-year). A contractor installing new equipment in stock like this has to assess whether the existing duct layout can move the volume the new unit produces, or whether sections need to be opened, rebalanced, or replaced before the system will perform as rated. The electrical service gets the same look: what the panel was wired to handle and what a new condenser and air handler actually draw are questions answered at the box, not on the spec sheet.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a pad outside the house and holds the compressor and the condenser coil, the two components that do the heaviest work in the system. Inside, the air handler or furnace blower sits in a utility closet, basement, or attic and pushes conditioned air through the home. These are the main pieces a contractor sets in place.
The evaporator coil mounts directly above the air handler and is where the refrigerant does its work on the air passing over it. A copper refrigerant line set runs between the indoor and outdoor units, and a condensate drain line carries moisture away from the coil to a floor drain or outside the home.
The drawing shows a typical central AC layout, and a licensed contractor determines which configuration and components apply to your specific home.

What the Installation Actually Looks Like
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 Dougherty County
Georgia's climate puts real load on cooling equipment, and Dougherty County gets its share of what that climate delivers. A system sized and installed for local conditions handles that load differently than one spec'd for somewhere else.
