Sizing a central AC system for a house in Granville County starts with what the house asks of the equipment, not with bracing for punishment from outside. 84 severe weather events were recorded in Granville County, North Carolina between 2015 and 2024. At that rate, severe weather is real but not relentless, and a contractor quoting an installation here spends the hard thinking on load calculation, duct layout, and equipment fit for the structure. A system undersized because the math was skipped will fail faster than one that has weathered every storm on that list.
Ductwork laid down for one generation of equipment does not automatically carry the next. Half the homes in Granville County, North Carolina were built in 1992 or earlier (2020-2024 ACS 5-year). A contractor scoping a central AC installation here checks whether the existing duct layout moves enough air volume for a modern system and whether the electrical service meets current draw requirements, before the new unit is ever priced. Where those two things line up, the job moves fast. Where they do not, the path forward is a duct modification or a panel upgrade, and the homeowner finds that out at the assessment, not after the equipment arrives.
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, which together shed heat pulled from inside. Indoors, the air handler or furnace with its evaporator coil mounts in a closet, attic, or utility room and is where the cooled air originates before it moves through the house.
The thermostat goes on an interior wall and is the control point for the whole system. Refrigerant line sets run between the outdoor and indoor units, and a condensate drain line carries moisture out from the evaporator coil to a floor drain or exterior exit point.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the construction of your home.

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.
