A contractor quoting a central AC installation in Jones County has to account for what the local climate actually demands of equipment, and the honest answer is that severe weather here is an occasional fact, not a steady operating pressure. 57 severe weather events were recorded in Jones County, North Carolina between 2015 and 2024. At that rate, most systems in this county spend the bulk of their lives running against summer heat and age, not weather events. Undersized equipment or a poor refrigerant charge on day one will cause more wear over a system's life than the weather record will, which is why a contractor sizes and seals the install carefully before anything else gets discussed.
Ductwork laid down for older equipment was sized and routed for what existed then, and a new central AC unit draws on that existing infrastructure from the first day it runs. Half the homes in Jones County, North Carolina were built in 1988 or earlier (2020-2024 ACS 5-year). That means a contractor assessing an installation here spends real time on what is already in the walls and crawlspace, checking whether the supply and return layout will carry the load the new system needs. If the ducting falls short, the equipment selection comes after, not before, that answer.
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, which are the core of the system. Inside, the air handler mounts in a utility closet, attic, or basement and moves conditioned air through the home. Together these two units make up the equipment a homeowner is purchasing.
The refrigerant line set runs between the outdoor and indoor units, connecting them through a small penetration in the wall. A thermostat goes on an interior wall and gives the homeowner control over the whole system. The condensate drain line runs from the air handler to a nearby drain, carrying away the moisture the system pulls from indoor air.
The drawing shows the general layout of a central AC system, and a licensed contractor determines what applies to your specific house.

What happens when a contractor installs your system in Jones 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.
