A contractor quoting a central AC install in Meriwether County has to make decisions about sizing and duct configuration that are specific to this house, not pulled from a regional catalog. 63 severe weather events were recorded in Meriwether County, Georgia between 2015 and 2024. At that rate, severe weather here is an occasional fact of life rather than a relentless operating condition, so a properly sized system should not need to be engineered around storm load as a primary concern. What the contractor does need to establish is whether the existing ductwork, air handler location, and electrical supply are sound, because those are what decide whether a new unit runs as specified or underperforms from its first season.
Ductwork laid down for equipment generations older than what runs in houses now is what a contractor prices against when quoting a central AC installation here. Half the homes in Meriwether County, Georgia were built in 1983 or earlier (2020-2024 ACS 5-year). That gap between when a house was built and what it is being asked to carry today is where installation work gets complicated or stays simple. Runs that made sense for an earlier system may be undersized for a current one, and electrical service put in at original construction was not designed around modern load requirements. The ductwork is what gets opened and measured before anything else.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and holds the compressor and condenser coil. Inside the house, the air handler or furnace-mounted evaporator coil sits in a mechanical room, basement, closet, or attic and is where the system meets the air that moves through your home.
A refrigerant line set runs between the two units, connecting the outdoor and indoor sides through an exterior wall. The thermostat goes on an interior wall and gives the homeowner a single point of control over the whole system.
The drawing shows a general layout of how these pieces relate to one another, and a licensed contractor determines what the installation requires in your specific 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 Meriwether County
Georgia's climate puts real demands on cooling equipment, and Meriwether County gets its share of weather that runs systems hard. How often that happens here shapes what a contractor specifies, how they size a unit, and what the installation needs to hold up to.
