A contractor quoting a central AC installation in Gilmer County has to decide what the equipment will actually be working against. 66 severe weather events were recorded in Gilmer County, West Virginia between 2015 and 2024. At that rate, severe weather is an event here, not a steady condition, which means sizing decisions and equipment selection rest on the home's load requirements and the quality of the install rather than on accumulated storm stress. A failed system in this county points a contractor toward how the original unit was put in and how long it ran, not toward weather history.
Ductwork laid down for a generations-old heating system carries assumptions about airflow that a new central AC unit will not share. Half the homes in Gilmer County, West Virginia were built in 1974 or earlier (2020-2024 ACS 5-year). A contractor quoting a central AC installation here opens the duct runs before anything else, checking whether the existing system can move the volume a modern unit requires without pressure drops or dead zones that cut efficiency from day one. If the ductwork needs rerouting or supplementing, that work sets the price, not the equipment selection. Electrical service gets the same check, since a panel original to a house of that age may not carry the load a new condenser pulls.
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, the two components that do the heaviest work in the system. Inside, the air handler or furnace cabinet lives in a utility space, basement, or attic and houses the evaporator coil, which is where the cooling actually occurs at the air.
A refrigerant line set runs between the two units, connecting the indoor and outdoor sides through the wall or floor. The thermostat mounts on an interior wall and is the control point the homeowner sees and uses every day, telling the system when to run.
The drawing shows a representative layout, and a licensed contractor determines exactly what goes where based on the specifics of the house.

What HVAC Installation Looks Like in Gilmer 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 Events in Gilmer County
Weather puts a direct load on cooling equipment. How hard a system has to work, and how long it lasts, is shaped by what the local climate throws at it, which makes this data relevant to any central AC installation in Gilmer County.
