Takes about a minute. No obligation.
A contractor quoting a central AC installation in Wilkinson County has to settle what the house actually needs before selecting equipment, and the local weather record is only a small part of that calculation. 41 severe weather events were recorded in Wilkinson County, Georgia between 2015 and 2024. At that rate, severe weather is an event here, not a standing condition, and it does not drive the sizing conversation the way it does in harder-hit areas. What drives it is the house: its age, its insulation, its existing ductwork. A contractor who gets those details wrong installs a system that runs short or runs long, and no amount of mild weather fixes that.
Ductwork laid down for an older system carries assumptions about airflow, routing, and load that a modern central AC unit does not share. Half the homes in Wilkinson County, Georgia were built in 1982 or earlier (2020-2024 ACS 5-year). A contractor installing a new system in a house from that era has to assess whether the existing ducts can move the air a current unit demands, not simply connect to what is there. If they cannot, the duct work becomes a job inside the job. The electrical service gets the same look, since panel capacity for a house of that vintage was set long before current equipment draws were standard.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a pad beside the house and holds the compressor and condenser coil, which together shed heat pulled from inside. The indoor air handler mounts in a utility closet, basement, or attic and carries the evaporator coil where the air passes through. These two units are what a homeowner is buying.
A refrigerant line set runs between the two units, carrying refrigerant back and forth through copper tubing. A new thermostat goes on an interior wall and serves as the control point for the whole system. The condensate drain line runs from the air handler to a nearby floor drain or outside the house to carry off moisture.
The drawing beside this section shows the general layout of a central AC system, and a licensed contractor determines exactly what applies to your home and how each piece is 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.
Severe Weather Events in Wilkinson County
Georgia's climate puts real pressure on cooling equipment, and Wilkinson County gets its share of that load. How hard a system has to work, and how long it lasts, is shaped by local conditions, which is why weather history belongs alongside any conversation about installation.
