A contractor quoting a new central AC installation in this area has to size for what the climate actually demands, not for what a generic load chart assumes. 135 severe weather events were recorded in Craven County, North Carolina between 2015 and 2024. At that rate, severe weather is a routine operating condition here, not an edge case, and a system undersized or poorly seated against it will run harder and cycle more than the equipment was built to sustain. That is why local contractors factor the area's weather history into how they spec the unit and how carefully they seal and position the installation from the start.
Ductwork sized and routed for an older system carries real consequences when a contractor fits a new central AC unit to it. Half the homes in Craven County, North Carolina were built in 1989 or earlier (2020-2024 ACS 5-year). That gap between what the house was built for and what runs in it now shows up in the ducts: whether they are sized to move the right volume of air, whether they are sealed well enough to deliver it, and whether the electrical service in the house meets what a new unit draws. A contractor who finds undersized returns or mismatched trunk lines has a different job ahead than one who does not.
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 shed heat to the outside air. Inside, the air handler or furnace cabinet stands in a utility closet, basement, or attic and contains the evaporator coil along with the blower that moves air through the house.
A copper refrigerant line set runs between the two units, connecting the indoor coil to the outdoor coil and carrying refrigerant between them. The thermostat mounts on an interior wall and gives the homeowner control over when the system runs.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this 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.

Severe Weather Events in Craven County
Weather puts load on cooling equipment, and how hard a system works over its life depends heavily on local conditions. That makes the history of severe weather in this area a practical fact for anyone sizing or installing central AC here.
