Sizing a central AC system in Brooke County starts with the structure: its layout, its insulation, its orientation and how it holds heat on a July afternoon. 51 severe weather events were recorded in Brooke County, West Virginia between 2015 and 2024. At that rate, severe weather is an event in the life of a system, not a steady operating condition, so a contractor quoting a new install is not building the spec around storm exposure. Age of the existing equipment, duct condition and the quality of the original install are what drive the numbers on a replacement job here.
Ductwork sized for an older heating system is a genuine constraint on what a new central AC unit can deliver, and in Brooke County the odds of finding exactly that behind the walls are real. Half the homes in Brooke County, West Virginia were built in 1966 or earlier (2020-2024 ACS 5-year). Houses built then were designed around equipment with different airflow demands, and the duct runs that satisfied those demands often fall short of what a modern cooling system needs. A contractor has to measure what is there, not assume it carries the new load. The electrical panel gets the same scrutiny, since a house of that vintage may not be wired for the draw a current-spec unit requires.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad or mounting surface outside the house and holds the compressor and condenser coil, the two components that do the heaviest work in the system. Inside, the air handler or furnace-and-coil assembly installs in a utility space, basement, or closet and circulates air across the evaporator coil before pushing it through the house.
A copper refrigerant line set runs between the outdoor and indoor units, connecting them through an exterior wall, and a condensate drain line carries moisture pulled from the indoor air out of the house. The thermostat mounts on an interior wall and gives the homeowner control over the whole system.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific home.

What happens on installation day
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.
