Sizing a central AC system in Wetzel County starts with what the local climate has asked of equipment here over time. 53 severe weather events were recorded in Wetzel County, West Virginia between 2015 and 2024. That record sits low in the national range, which means severe weather is an occasional event in this area rather than a standing condition. When a system is failing before a new install, age and the quality of the original installation are almost always the explanation, and the weather is not. A contractor quoting a replacement here prices the job around load calculations, duct condition, and the structure of the house.
Ductwork laid down for a furnace and a register arrangement that predates central cooling does not automatically carry a new system well. Half the homes in Wetzel County, West Virginia were built in 1962 or earlier (2020-2024 ACS 5-year). A contractor sizing and installing central AC in housing of this vintage has to assess what the existing ducts can actually move and where the electrical service lands before the equipment choice matters at all. Panels from that era were sized for a different load. What a contractor finds in the walls and the attic sets the scope of the job.
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 cabinet mounts in a utility space, basement, or closet and holds the evaporator coil that does the cooling work at the air side.
A copper refrigerant line set runs between the two units, connecting the outdoor and indoor coils into one closed loop. The thermostat goes on an interior wall where it reads the living space and signals the system to run or stop.
The drawing shows the general layout of a central AC system, and a licensed contractor determines exactly what applies to this house.

What HVAC Installation Looks Like in Wetzel 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.
