A contractor quoting a central AC installation in Nash County has to account for the local weather record before settling on equipment size or installation spec. 135 severe weather events were recorded in Nash County, North Carolina between 2015 and 2024. At roughly that rate, severe weather is a real but manageable part of the operating environment, and a system installed to the right spec for this area will handle it. What actually shortens a system's life here is undersizing for the cooling load or shortcuts in the original install, and those are decisions a contractor makes before the unit ever runs its first summer.
Ductwork laid down for older equipment carries assumptions about airflow and routing that a new central AC system will not share. Half the homes in Nash County, North Carolina were built in 1986 or earlier (2020-2024 ACS 5-year). A contractor installing a new system in a house from that era has to assess whether the existing duct runs can move the volume a modern unit pushes, or whether sections need to be rerouted before the new equipment is ever connected. The electrical side matters too, since panel capacity in houses of that vintage was not planned around the draw of current equipment. What the house already contains sets the scope of the job before any unit is ever selected.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and houses the compressor and condenser coil. Inside, the air handler mounts in a utility closet, attic, or basement and holds the evaporator coil and blower that push conditioned air through the home.
The thermostat goes on an interior wall where the homeowner sets and reads the temperature. A condensate drain line runs from the air handler to a floor drain or outdoors, carrying away the moisture the system pulls from indoor air.
The drawing shows a typical central AC layout, and a licensed contractor determines exactly what applies to your house.

What AC Installation Looks Like in Nash 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.
