Sizing central AC for a Richmond County home is a local question, not a catalog one. The load profile here depends on what this county's climate actually demands, and severe weather is part of that picture. 69 severe weather events were recorded in Richmond County, North Carolina between 2015 and 2024. At roughly the thirty-first percentile nationally, that record puts this county in the quieter range, which means storm exposure alone seldom drives what a system needs. A contractor quoting an installation here is working through duct layout, building envelope, and how the house holds heat rather than designing around a punishing weather load.
Ductwork laid down for one generation of cooling does not automatically carry the next one. Half the homes in Richmond County, North Carolina were built in 1976 or earlier (2020-2024 ACS 5-year). That gap between when the house was built and what a contractor installs in it today is where installation jobs either hold their budget or break it. If the existing ducts are undersized or misrouted for a modern system's airflow, the unit gets installed and never performs correctly. The electrical service is the second variable: older panels are wired for load draws that do not match current equipment. A contractor who opens walls and ceilings before writing a number is not being slow.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad outside the house and holds the compressor and condenser coil, the two components that do the heaviest work in the system. Inside, the air handler or furnace-mounted evaporator coil lives in a closet, attic, or utility room and is the point where cooled air enters the duct system.
The thermostat goes on an interior wall and gives the homeowner direct control over the system. A refrigerant line set runs between the indoor and outdoor units, and a condensate drain line carries moisture pulled from the air to a floor drain or outside.
The drawing shows how these pieces relate in a typical installation, and a licensed contractor determines what the layout looks like in your specific 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.
