Sizing a central AC system in Braxton County starts with what the local climate actually asks of the equipment. 64 severe weather events were recorded in Braxton County, West Virginia between 2015 and 2024. At that rate, severe weather is a regular part of the operating life of any system installed here, and a contractor who ignores it will undersize the unit or select components that cannot hold up under the load. The spec has to reflect that reality before anything gets ordered.
Ductwork laid down before central air conditioning was a common feature of residential construction was sized, routed, and sealed for a different job. Half the homes in Braxton County, West Virginia were built in 1977 or earlier (2020-2024 ACS 5-year). That gap between what the house was built to do and what a new system needs from it is where a central AC installation in Braxton County actually gets complicated. A contractor working here has to assess whether the existing duct runs can carry the load and move air where it needs to go before the equipment choice means much at all. Electrical service gets the same look.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a pad outside the house and holds the compressor and condenser coil, which are the mechanical heart of the system. Inside, the air handler or furnace-mounted evaporator coil lives in a utility space, basement, or closet and is the indoor half of the refrigerant circuit. A refrigerant line set runs between them, connecting the two units.
The thermostat goes on an interior wall where the homeowner controls the whole system from a single point. A condensate drain line runs from the indoor coil to a floor drain or outside, carrying away the moisture the coil pulls from the air. Together these pieces form a complete, house-wide cooling system.
The drawing shows the general layout of a central AC system, and a licensed contractor determines exactly what applies to your house.

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.
