A contractor quoting central AC in Berkeley County has to account for what this climate actually demands before settling on capacity or equipment class. 138 severe weather events were recorded in Berkeley County, West Virginia between 2015 and 2024. Severe weather at that rate is a standing condition of operation here, not an occasional interruption, and it feeds directly into how a system gets sized and what the install has to tolerate across its working life. A unit that would run comfortably in a quieter climate may be underbuilt for this one, and a contractor who treats sizing as a catalog lookup will specify accordingly.
Ductwork laid in for older equipment does not automatically carry a modern central AC system, and in Berkeley County a large share of the housing stock was built around exactly that older equipment. Half the homes in Berkeley County, West Virginia were built in 1996 or earlier (2020-2024 ACS 5-year). A contractor sizing a new system here checks the existing duct runs and the electrical service before the unit selection means anything. If the ducts are undersized or the panel cannot support the load, that work comes first. The equipment choice follows from what the house already contains.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad along a side or rear wall, and houses the compressor and condenser coil. Inside, the air handler or furnace-and-coil assembly installs in a utility space, basement, or closet, where it moves air through the system. Together these two units form the core of what a contractor puts in.
The refrigerant line set runs between the indoor and outdoor units, typically along an exterior wall or through a small chase cut into the structure. A thermostat goes on an interior wall and gives the homeowner direct control over the system. The contractor also connects the system to the home's existing supply and return vents.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the specific house.

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.
