A contractor quoting a central AC installation in Habersham County has to size the system for what this climate actually demands, and that starts with the building, not a catalog. 50 severe weather events were recorded in Habersham County, Georgia between 2015 and 2024. At that rate, severe weather is an event here, not a standing condition every system runs against year-round. That shifts the weight of a good install onto load calculations, equipment selection, and how well the refrigerant lines and air handler are set up for this house, because those decisions are what determine how the system performs over the years ahead.
Ductwork in a house this old was designed around whatever unit it came with, and that original sizing is what a contractor has to measure and pressure-test before anything else can be quoted. Half the homes in Habersham County, Georgia were built in 1992 or earlier (2020-2024 ACS 5-year). A new central AC unit draws different airflow requirements than the one it replaces, and ducts that were never modified to accommodate changes along the way will show it in static pressure readings. The electrical panel is the second variable: service capacity installed in that era frequently falls short of what modern equipment draws, and a contractor has to confirm the available amperage before a system can be matched to the house.
What Gets Installed With a New Central AC
The outdoor unit sits on a concrete pad beside the house and holds the compressor and condenser coil. Inside, the air handler or furnace-and-coil combination lives in a closet, attic, or basement and moves conditioned air through the home. These two units are what a contractor brings to a Central AC installation.
A refrigerant line set runs between the outdoor unit and the indoor coil, connecting the two halves of the system through an exterior wall. The thermostat on an interior wall is the control point, and a new installation often includes replacing it to work with the new equipment.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your home's configuration.

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 Habersham County
Habersham County weather puts real demands on cooling equipment, and those demands shape what a system needs to handle over its life. That is a local variable, and it belongs in any honest conversation about what to install here.
