A contractor quoting a central AC install in Kanawha County has to account for what the climate here regularly demands of the equipment, because that shapes every decision from unit sizing to where the air handler sits. 317 severe weather events were recorded in Kanawha County, West Virginia between 2015 and 2024. At that rate, severe weather is a standing condition of operating here, and a system sized for a calmer environment will be undersized for this one. Duct layout, refrigerant line routing, and equipment capacity are local questions in this county, not answers pulled from a manufacturer's defaults.
Ductwork sized and routed for an earlier era of home comfort shapes what a contractor actually encounters when quoting a central AC installation in Kanawha County. Half the homes in Kanawha County, West Virginia were built in 1966 or earlier (2020-2024 ACS 5-year). That means the ducting running through a large share of local homes was never engineered for the static pressure and airflow a modern central system expects, and a contractor pulling permits here opens walls and chases to check what is there before committing to a layout. The electrical is the same story: service panels from that period were sized for a different load, and what is there has to be verified against what the new equipment will draw.
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, the two components doing the heaviest work in the system. Inside, the air handler mounts in a utility space, basement, or attic and contains the evaporator coil and blower that move conditioned air through the home.
The thermostat goes on an interior wall where it reads the temperature and tells the system when to run. A condensate drain line runs from the air handler to a nearby drain, and refrigerant lines connect the indoor and outdoor units, running through the wall or ceiling to tie the two halves together.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific house.

What HVAC Installation Looks Like in Kanawha 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.
