A contractor quoting central AC installation in Forsyth County has to work out what the local climate actually demands before settling on equipment size and refrigerant line routing. 76 severe weather events were recorded in Forsyth County, Georgia between 2015 and 2024. At that rate, severe weather is an occasional fact of life here rather than a constant operating condition, which means the sizing decisions and install quality a contractor makes carry more weight than storm exposure does. A system that fails early in this county almost certainly failed because it was undersized, poorly charged, or badly matched to the home. The weather record gives a contractor useful context. It does not give them an excuse.
Ductwork and electrical service installed in a house built around that era were put in for central air, not retrofitted to accommodate it later. Half the homes in Forsyth County, Georgia were built in 2004 or earlier (2020-2024 ACS 5-year). A contractor sizing a new system here is not untangling decades of piecemeal adaptation the way they would be in stock built for window units and space heaters. The panel and the trunk lines were laid out for a forced-air system, which means the evaluation turns on the condition of what is there, not on whether it belongs.
What Gets Installed With a New Central AC
The outdoor unit, called the condenser, sits outside the house on a concrete pad and holds the compressor and condenser coil. Inside, the air handler mounts in a closet, attic, or utility room and contains the evaporator coil along with the blower that moves air through the house. These are the two main pieces a homeowner is buying.
A refrigerant line set runs between the outdoor and indoor units, connecting the two and carrying refrigerant between the coils. The thermostat goes on an interior wall where it reads the air temperature and tells the system when to run. A condensate drain line also runs from the air handler to carry away the moisture the coil pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house based on its construction and existing infrastructure.

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 Forsyth County
Weather stress shapes how hard HVAC equipment has to work and how long it holds up doing it. For central AC installation in this area, local conditions are part of the sizing and equipment conversation, not an afterthought.
