Sizing central AC in Cleveland County is a local calculation, not a catalog lookup by square footage alone. 117 severe weather events were recorded in Cleveland County, North Carolina between 2015 and 2024. A contractor working here has to account for the load that weather puts on a system over its life, because equipment sized for an average climate will run longer cycles and accumulate wear faster than the specs suggest. That gap shows up at install time, in how the contractor calculates the load and selects the unit, before the homeowner ever turns it on.
Ductwork put in decades ago was sized and routed for what was running then, and a new central AC system draws differently than what those runs were built around. Half the homes in Cleveland County, North Carolina were built in 1979 or earlier (2020-2024 ACS 5-year). A contractor assessing a job here measures what the existing duct network will actually carry before the unit itself enters the conversation. Where the runs are too restrictive or too leaky, the installation price and scope shift accordingly, because patching around undersized ductwork produces an underperforming system regardless of what sits on the pad outside.
What Gets Installed With a New Central AC
The indoor air handler sits inside the house, usually in a utility closet, attic, or basement, and it holds the evaporator coil that pulls heat out of the air moving through your home. The outdoor condenser unit sits on a concrete pad beside the house and carries the compressor and the condenser coil, which release that heat outside.
A refrigerant line set runs between the two units, connecting the indoor and outdoor sides so the system works as one. A thermostat goes on an interior wall where it reads the air temperature and tells the system when to run.
The drawing shows a typical central AC layout, and a licensed contractor determines what the installation calls for in your specific home.

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.
