A contractor quoting central AC installation in Fayette County has to account for what the local climate genuinely asks of a system, and the county's record is real enough to take seriously. 114 severe weather events were recorded in Fayette County, West Virginia between 2015 and 2024. That puts severe weather in the range of an occasional condition rather than a relentless one, which means the load on a new system matters but does not override the basics: proper sizing for the structure, tight duct connections, and a refrigerant charge set to the manufacturer's spec. A system that misses on any of those will fail on its own terms, and the weather here will not take the blame.
Ductwork laid in for the equipment of a different era carries assumptions about airflow, load, and routing that a new central AC system does not share. Half the homes in Fayette County, West Virginia were built in 1972 or earlier (2020-2024 ACS 5-year). A contractor sizing and placing a new unit here has to assess what those ducts will actually deliver before anything else on the job is settled, because the answer changes both what equipment fits and what the install involves. The electrical service gets the same look, since the draw of current equipment does not always match what the panel was set up to handle.
What Gets Installed With a New Central AC
The outdoor unit sits on a concrete pad beside the house and holds the compressor and condenser coil. Inside, the air handler mounts in a utility closet, basement, or attic and contains the evaporator coil and blower fan. These are the two main pieces a homeowner is buying.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two cabinets through a small penetration in the wall. The thermostat goes on an interior wall where it reads the living space and tells the system when to run.
The drawing shows a typical layout, and a licensed contractor determines exactly what fits and where in your particular house.

What the installation looks like in Fayette 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.

Severe Weather in Fayette County
Weather stress is one of the main reasons HVAC equipment wears or fails ahead of schedule. How hard the climate pushes on a system determines what size and spec a contractor needs to install, and that answer is specific to where the home sits.
