A contractor quoting a central AC installation in Person County has to account for what the climate actually asks of equipment, not just the square footage of the house. 136 severe weather events were recorded in Person County, North Carolina between 2015 and 2024. At roughly the sixty-ninth percentile nationally, severe weather here is a standing condition, not a rare disruption, and that shapes how a contractor sizes the system before any equipment gets ordered. A unit speced for a milder place runs harder, cycles more, and reaches its limits sooner. Getting the load calculation right at installation is what keeps that from happening.
Ductwork laid down for an earlier generation of equipment is what a contractor has to evaluate before the installation scope is clear. Half the homes in Person County, North Carolina were built in 1983 or earlier (2020-2024 ACS 5-year). A house that old was ducted for systems with different airflow requirements, different static pressure, and different return configurations than what gets installed today. The electrical service is a secondary question, one the contractor answers at the panel. It is the duct layout, and whether it can carry the load a new unit moves, that sets the job's complexity and its cost.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, which together shed heat to the outside air. Inside, the air handler mounts in a utility closet, attic, or basement and contains the evaporator coil and blower that push conditioned air through the home.
The thermostat goes on an interior wall where it reads the home's air temperature and tells the system when to run. A copper refrigerant line set runs between the outdoor and indoor units, and a condensate drain line carries moisture pulled from the air out of the house.
The drawing shows the general layout of a central AC system, and a licensed contractor determines exactly what applies to your house.

What the installation looks like in Person 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.
