A contractor quoting a central AC installation in Warren County is not pricing against a punishing storm record. 77 severe weather events were recorded in Warren County, North Carolina between 2015 and 2024. At that rate, severe weather is an occasional event rather than a standing pressure on equipment, and the conditions that drive sizing decisions here are the ones present every summer: the age of the existing ductwork, the heat load of the structure, and whether a previous install was done well. A system that has run through years of ordinary cooling seasons in this area fails for those reasons. The installation answer, then, is local in the way every installation is local, built around what the house asks of the equipment, not around storm hardening.
Ductwork laid in for older equipment carries assumptions about airflow, return paths, and trunk sizing that a new central AC system may not share. Half the homes in Warren County, North Carolina were built in 1988 or earlier (2020-2024 ACS 5-year). A contractor quoting an installation here has to open registers, trace runs, and check whether what is already in the walls and crawlspace will move air the way a new unit requires. If it will not, the duct work gets modified before the equipment question is even settled. The electrical service gets the same look, since a panel wired for the loads of that era often needs an upgrade to run modern condensing equipment.
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 doing the heaviest work in the system. Inside, the air handler mounts in a utility space, basement, or attic and circulates air across the evaporator coil, which is housed within it.
The thermostat goes on an interior wall where it reads the air temperature and signals the system to run or stop. A contractor also installs the refrigerant lines that run between the outdoor unit and the air handler, and the condensate drain line that carries moisture out of the house.
The drawing shows a representative layout, and a licensed contractor determines exactly what goes where based on the specifics of your house.

What the installation looks like in Warren 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.

Severe Weather Events in Warren County
Weather puts a direct load on cooling equipment: the more a system gets pushed, the more the install has to be sized and built to handle it. What the climate does in Warren County shapes what contractors specify here.
