Sizing central AC for a home here starts with what the system will actually run against year after year. 100 severe weather events were recorded in Tallapoosa County, Alabama between 2015 and 2024. At that rate, severe weather is a standing condition, and a contractor who ignores it when selecting equipment leaves a homeowner with a system that was never built for the job. Duct routing, unit placement, and the spec of the equipment itself are all local decisions in Tallapoosa County, not defaults pulled from a catalog.
Existing ductwork is what a central AC installation in Tallapoosa County turns on. Half the homes in Tallapoosa County, Alabama were built in 1985 or earlier (2020-2024 ACS 5-year). Ducting from that period was laid out for equipment with different load characteristics than what contractors install today, and the question of whether it carries a new system well enough is not answered by looking at it from the outside. A contractor has to assess airflow, check the routing, and judge whether what is there does the job or needs work before anything gets sized or quoted. The electrical service gets the same look.
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 the condenser coil, which together shed heat collected from inside. The indoor air handler mounts in a utility closet, attic, or basement and houses the evaporator coil and the blower that moves conditioned air through the home.
The refrigerant line set runs between the two units, carrying refrigerant back and forth through insulated copper tubing. A thermostat mounts on an interior wall and serves as the control point, signaling the system when to run and when to stop.
The drawing shows a typical layout, and a licensed contractor determines what the configuration looks like in your specific house.

What HVAC Installation Looks Like in Tallapoosa 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 Tallapoosa County
Weather puts a load on HVAC equipment, and that load is not the same everywhere. A system sized and installed for what actually happens in Tallapoosa County holds up differently than one spec'd for somewhere else.
