A contractor sizing and installing central AC here works out what the house actually needs before anything goes on order, because poor original installs are what most replacement jobs trace back to. 20 severe weather events were recorded in Towns County, Georgia between 2015 and 2024. At that rate, severe weather is an event a system here encounters now and then, not a steady operating pressure that wears components ahead of schedule. A unit that has run in this county and failed almost certainly failed from age, undersizing at the original install, or skipped maintenance. The quote a contractor builds here is driven by the house, the load, and what was done before.
Ductwork laid for an earlier generation of equipment carries assumptions about airflow and load distribution that a new central AC system does not share. Half the homes in Towns County, Georgia were built in 1995 or earlier (2020-2024 ACS 5-year). A contractor quoting an installation in housing like this spends real time on what is already in the walls and attic, not just on the unit itself, because routing that made sense for older equipment can create static pressure problems for a modern system. Electrical service gets the same look. If the existing duct layout cannot support the new system, the scope and the bill change before the equipment is ever ordered.
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, the two components that do the heaviest work in the refrigeration cycle. Inside, the air handler mounts in a closet, attic, or utility room and moves conditioned air through the home. Together these two units form the core of what a contractor installs.
The copper refrigerant lines run between the outdoor and indoor units, connecting the two sides of the system, and a new installation includes the line set sized to match the equipment. The thermostat goes on an interior wall and gives the homeowner control over the whole system. A condensate drain line also runs from the air handler to carry away the moisture the coil pulls from indoor air.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house and its existing setup.

What HVAC Installation Looks Like in Towns County
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.
