A contractor quoting a central AC installation in Macon County has to account for what the site actually demands, and severe weather is a minor variable in that calculation. 35 severe weather events were recorded in Macon County, North Carolina between 2015 and 2024. At that rate, the weather record here does not drive the sizing conversation the way it does in harder-hit areas of the state. What shapes a proper install is the age of the existing ductwork, the layout of the house, and how well the original system was put in. A contractor who gets those three right produces a system that runs efficiently regardless of what the occasional storm season brings.
Ductwork laid down for an older generation of equipment carries different sizing assumptions than what a modern central AC system needs to move air correctly. Half the homes in Macon County, North Carolina were built in 1987 or earlier (2020-2024 ACS 5-year). A contractor pricing a new installation here has to assess what is already in the walls and crawlspaces before any unit gets selected, because ductwork that does not match the new system's airflow requirements will pull efficiency down from day one. The electrical service in houses of this vintage is the same question: whether the panel supports what the new equipment draws is something that gets confirmed on-site, not assumed from a zip code.
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 system. Inside, the air handler mounts in a utility closet, attic, or basement and moves air across the evaporator coil. These two units are the core of what a contractor sets in place.
A copper refrigerant line set runs between the indoor and outdoor units, connecting them through the wall or floor. The thermostat mounts on an interior wall and is the control point the homeowner touches. A condensate drain line 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 what fits the specifics of your 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.
