A contractor quoting a central AC install in Columbus County has to size for what this area actually demands, and the weather record is part of that picture. 110 severe weather events were recorded in Columbus County, North Carolina between 2015 and 2024. At roughly the midpoint nationally, that rate of severe weather is real but not the dominant variable shaping an install. What decides whether a system performs well over years is how the equipment is sized for the home and how the refrigerant lines, ductwork, and drainage are put in. A contractor who skips that work in favor of dropping in a standard unit leaves the homeowner with a system that runs hard and short.
Ductwork laid out for older equipment runs different paths, carries different static pressure, and was sized to move air for systems that no longer exist. Half the homes in Columbus County, North Carolina were built in 1982 or earlier (2020-2024 ACS 5-year). A contractor pricing a central AC installation in this county has to assess whether those ducts can actually deliver what a new unit will push through them, and whether the existing electrical service will carry the load. Those two questions decide the scope of the job before any equipment is even selected.
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 hardware that does the core work of the system. Inside, the air handler or furnace cabinet stands in a utility room, basement, or closet and holds the evaporator coil and blower that move conditioned air through the home.
The thermostat mounts on an interior wall and gives the homeowner control over the whole system. Refrigerant lines run between the outdoor unit and the indoor cabinet, and a condensate drain line carries moisture out of the air handler to a floor drain or exterior exit point.
The drawing shows a standard central AC layout, and a licensed contractor determines exactly what the installation involves in your house.

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.
