Sizing a central AC system in Crawford County starts with the structure: square footage, insulation, window placement, duct condition. 44 severe weather events were recorded in Crawford County, Georgia between 2015 and 2024. At that rate, severe weather is a real but infrequent presence, not the governing variable a contractor is building around. What shapes the install is how this particular house holds and loses air, and a contractor who quotes without a load calculation is guessing at both the equipment and the bill.
Ductwork laid in for older equipment carries assumptions about airflow, static pressure, and system size that a new central AC unit may not share. Half the homes in Crawford County, Georgia were built in 1993 or earlier (2020-2024 ACS 5-year). A contractor installing a new system in a house from that era has to confirm whether the existing duct layout will actually move air the way the new equipment expects, and whether the electrical service will support the load. If the ducts are undersized or the panel needs work, that gets priced and scoped before the new unit is ever ordered.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad outside the house and holds the compressor and condenser coil, the two components that shed heat from the refrigerant. Inside, the air handler or furnace-and-coil assembly occupies a closet, basement, or utility space and is the piece that cools air before it moves through the house.
A refrigerant line set runs between the outdoor and indoor units, connecting them through an exterior wall. The thermostat mounts on an interior wall and is the control point the homeowner will interact with every day. An expansion valve, filter drier, and condensate drain line round out what a contractor brings into the system.
The drawing shows a general layout of these components, and a licensed contractor determines exactly what applies to this house.

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 Crawford County
Georgia's climate puts real pressure on cooling equipment, and Crawford County gets its share of that pressure through storms that strain systems at the moments demand runs highest. How often severe weather hits a county shapes how hard the equipment works and how well it needs to be built to keep up.
