A contractor quoting central AC installation in Tyler County has to size for the house, not for a weather siege. 65 severe weather events were recorded in Tyler County, West Virginia between 2015 and 2024. At that rate, severe weather is an event in this county, not a standing condition, which means the system a contractor installs will spend most of its life running against summer heat and an aging duct layout rather than against recurring storm load. Sizing decisions, refrigerant line placement, and the quality of the initial install carry more weight here than any weather-hardening consideration.
Ductwork laid down for a furnace was never sized or routed for the air volumes a central AC system pushes, and in Tyler County a large share of the housing stock was built before central air was a standard feature of new construction. Half the homes in Tyler County, West Virginia were built in 1968 or earlier (2020-2024 ACS 5-year). A contractor installing a new central AC unit in a house from that era has to evaluate whether the existing duct system can carry the load before any equipment decision is final. Undersized trunks, missing returns, or ductwork that simply dead-ends in an addition are common findings. The electrical service gets the same look, since panels from that period often need an upgrade to handle a modern condensing unit.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, the two components that do the heaviest work in the system. Inside, the air handler mounts in a utility space, basement, or attic and houses the evaporator coil and the blower that moves air through the home.
A metering device, usually an expansion valve, mounts at the evaporator coil and controls how refrigerant enters it. The thermostat goes on an interior wall and serves as the control point for the whole system, telling the air handler and condenser when to run.
The drawing shows a standard layout, and a licensed contractor determines exactly which components and configurations apply to your house.

What the Installation Actually Looks Like
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 Events in Tyler County
Weather puts a measurable load on HVAC equipment, and that load is local. What the climate does in Tyler County shapes how hard a central AC system has to work and how long it holds up, which is why local conditions belong in any honest conversation about installation.
