A contractor quoting central AC in this area has to settle on sizing before anything else, and the local climate is a real input to that calculation. 132 severe weather events were recorded in Cumberland County, North Carolina between 2015 and 2024. At that rate, severe weather is a standing feature of operating here, which means the load assumptions baked into a standard catalog spec can fall short. A unit sized without accounting for this will run harder than it was built to, and the install pays for that gap for years.
Ductwork laid down for an older system carries assumptions about airflow, load, and routing that a new central AC unit does not automatically inherit. Half the homes in Cumberland County, North Carolina were built in 1988 or earlier (2020-2024 ACS 5-year). A contractor sizing and placing new equipment in stock like this has to assess what the existing duct runs will actually deliver before anything else is priced or ordered. Flex runs may be undersized, trunk lines may be routed in ways that made sense for a different system, and the electrical service may need evaluation alongside the duct work. The ductwork is where the installation decision gets made.
What Gets Installed With a New Central AC
The outdoor unit sits on a concrete pad beside the house and holds the compressor and condenser coil. Inside, the air handler mounts in a utility closet, attic, or basement and moves conditioned air through the home. Together these two units form the core of what a contractor brings and sets in place.
The refrigerant line set runs between the outdoor unit and the air handler, connecting the two through a small penetration in the wall. A thermostat goes on an interior wall where it reads the home's temperature and tells the system when to run. The condensate drain line carries moisture pulled from the air to a nearby drain or outdoors.
The drawing shows a typical layout, and a licensed contractor determines what fits and where in your specific home.

What Happens During an HVAC Installation in Cumberland 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 Cumberland County
Weather puts a load on cooling equipment, and that load is shaped by local conditions. How hard the climate pushes here is part of what determines what a system needs to handle year after year.
