Takes about a minute. No obligation.
A contractor quoting central AC installation in Haralson County has to settle what the house actually demands before anything else, and the weather record is a smaller part of that calculation than homeowners often expect. 49 severe weather events were recorded in Haralson County, Georgia between 2015 and 2024. At that rate, severe weather is an event in this county, not a standing condition, so a sizing decision rests mainly on the structure itself: square footage, insulation, window exposure, and how the ductwork is laid out. A system that gets those variables right from the first day will carry this climate without strain.
Ductwork laid in for older equipment carries assumptions about airflow and load that a new central AC system does not share. Half the homes in Haralson County, Georgia were built in 1989 or earlier (2020-2024 ACS 5-year). A contractor sizing and installing a new unit has to assess whether those existing ducts move enough air, are sealed adequately, and are routed in a way the new system can actually use. Where the ductwork falls short, the installation expands to include it. The electrical service gets the same check: what the house was wired for and what a modern condenser draws are not always the same number.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, the hardware that does the heavy lifting of the refrigeration cycle. Inside, the air handler or furnace-based coil assembly mounts in a closet, attic, or utility room and connects to the duct system that runs through the house.
A refrigerant line set runs between the outdoor and indoor units, carrying refrigerant back and forth through insulated copper lines. The thermostat goes on an interior wall and is the control point for the whole system, telling the equipment when to run and when to stop.
The drawing shows a typical layout, and a licensed contractor determines exactly what goes where based on this particular house.

What the Installation 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 Haralson County
Weather patterns shape how hard HVAC equipment has to work and how much stress it absorbs over its life. A central AC system sized and installed for local conditions holds up better than one that was not, and that makes the climate record here relevant to any installation decision.
