Sizing a central AC system in Pitt County starts with what the climate actually asks of the equipment, and the record here is neither light enough to ignore nor heavy enough to let it drive every decision. 102 severe weather events were recorded in Pitt County, North Carolina between 2015 and 2024. At that rate, severe weather is a real variable in how hard a system runs over its life, but it does not by itself determine what size unit a house needs or how it should be installed. A contractor who skips proper load calculations and leans on the weather record to justify a particular unit is skipping the work. Duct layout, insulation, and the specifics of the house are what decide the right system here.
Ductwork laid for older equipment runs at dimensions, layouts, and static pressure assumptions that do not match what a modern central AC unit needs. A contractor quoting an installation here pulls back access panels before pricing anything, because whether the existing duct network can carry the new system is what the quote actually depends on. Half the homes in Pitt County, North Carolina were built in 1994 or earlier (2020-2024 ACS 5-year). That means the electrical service gets checked too, since panels of that era were not always wired for current load requirements. What the house already contains decides the job.
What Gets Installed With a New Central AC
The outdoor unit sits on a pad beside the house and holds the compressor and condenser coil, which together shed heat pulled from inside. The indoor air handler mounts in a utility space, basement, or attic and contains the evaporator coil and blower that push conditioned air through the home.
A copper refrigerant line set runs between the two units, and a thermostat goes on an interior wall where it reads the temperature of the living space and signals the system to run. A condensate drain line carries moisture out from the air handler to a nearby drain or to the exterior.
The drawing shows a typical layout, and a licensed contractor determines what fits your specific 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.
