A contractor quoting a central AC install in Transylvania County has to account for what the building actually demands, because the weather record here does not point to a climate that routinely punishes equipment. 42 severe weather events were recorded in Transylvania County, North Carolina between 2015 and 2024. At that rate, severe weather is an occasional fact of life, not a standing condition a new system must be built to absorb above all else. Sizing decisions land on the house itself: its square footage, insulation, window exposure, and how the existing ductwork is laid out. Those are what drive the spec.
Ductwork sized and routed for older equipment is what a contractor meets in a large share of Transylvania County homes, and it either fits the load a new central system requires or it does not. Half the homes in Transylvania County, North Carolina were built in 1984 or earlier (2020-2024 ACS 5-year). Housing built in that era was designed around airflow assumptions that modern central AC does not share, which means the duct layout is the first thing a contractor has to evaluate, not the last. The electrical service runs a close second. A panel that was adequate for what the house originally ran may not carry what a new central unit draws, and that answer comes from what is actually in the walls, not from the year on the permit.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and holds the compressor and condenser coil. The indoor air handler or furnace cabinet lives in a utility room, basement, or attic and contains the evaporator coil and blower that move air through the home.
The two units connect through a pair of refrigerant lines that run between them, along with a condensate drain line that carries moisture away from the indoor coil. A thermostat mounts on an interior wall and serves as the control point for the whole system.
The drawing shows a typical layout, and a licensed contractor determines what applies to this specific house.

What AC Installation Looks Like in Transylvania 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.
