A contractor quoting a central AC installation in Wilcox County works from the specifics of the house: its square footage, insulation, duct layout, and sun exposure. 45 severe weather events were recorded in Wilcox County, Alabama between 2015 and 2024. At that rate, severe weather is an occasional event rather than a standing condition, which means the weather record does not drive sizing decisions here the way it might elsewhere. What drives them is the building itself. A contractor who skips the load calculation and pulls a unit size from a catalog is likely to leave the homeowner with a system that short-cycles or runs longer than it should.
Ductwork laid in for older equipment carries assumptions about airflow, static pressure, and load that a new central AC system will stress differently. Half the homes in Wilcox County, Alabama were built in 1985 or earlier (2020-2024 ACS 5-year). A contractor installing a new system in stock like this opens duct runs and checks whether they are sized for what the new unit will actually push through them. If the existing ductwork cannot carry the load, the installation price changes before the equipment is even ordered.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a pad outside the house and holds the compressor and condenser coil, which together shed heat to the outside air. Inside, the air handler or furnace cabinet mounts in a utility space, basement, or attic and holds the evaporator coil that pulls heat out of the air moving through your home.
A refrigerant line set runs between those two cabinets, connecting the indoor and outdoor sides of the system. A thermostat mounts on an interior wall and gives you control over the whole thing. The condensate drain line runs from the air handler to a floor drain or outside, carrying away the moisture the coil pulls from the air.
The drawing shows the general layout of a central AC system, and a licensed contractor determines exactly what applies to your house and how each piece gets positioned within it.

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.
Licensing and Legal Requirements in Wilcox County, Alabama
Alabama requires state certification to do heating, air conditioning and refrigeration contracting: nobody may advertise, bid, pull permits or do the work unless the person in responsible charge is a certified contractor.
Severe Weather Events in Wilcox County
Alabama's climate puts real stress on cooling equipment, and Wilcox County gets its share of that load. What the air outside does over time shapes how hard a system has to work and how well it needs to be sized and installed.
