Sizing central AC for a home in Screven County starts with what the climate actually asks of a system, not what a catalog default assumes. 120 severe weather events were recorded in Screven County, Georgia between 2015 and 2024. At that rate, severe weather is a standing condition of operating here, and a contractor who treats it as a rare edge case will undersize equipment or skip installation details that the local load makes necessary. Refrigerant line protection, equipment placement, and unit ratings all get weighed against what this area regularly puts a system through.
Ductwork laid down for an older generation of equipment carries assumptions about airflow, trunk sizing, and return placement that do not automatically match what a new central AC system needs to move. Half the homes in Screven County, Georgia were built in 1982 or earlier (2020-2024 ACS 5-year). A contractor sizing and installing a new system in this county has to evaluate what the existing ducts can actually deliver before anything else is priced or ordered. If the ductwork cannot support the load, the electrical panel is the next question. The unit itself comes last.
What Gets Installed With a New Central AC
The indoor air handler sits inside the home, most often in a closet, attic, or utility room, and it holds the evaporator coil that pulls heat out of the indoor air. The outdoor condenser unit sits on a concrete pad beside the house and carries the compressor, which is the engine of the whole system.
A refrigerant line set runs between the two units, carrying refrigerant back and forth through copper tubing that gets routed along the exterior wall or through the attic. A programmable thermostat goes on an interior wall and gives the homeowner control over when and how the system runs.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the configuration of your house.

What Happens During an HVAC Installation in Screven 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 Screven County
Screven County's climate puts real load on cooling equipment, and that load is shaped by local conditions that vary year to year. Sizing and installing central AC here means accounting for what the weather actually does in this area, not somewhere else.
