Sizing central AC in Mineral County means accounting for what the equipment will actually face, not what a typical install guide assumes. 128 severe weather events were recorded in Mineral County, West Virginia between 2015 and 2024. At that rate, severe weather is part of the normal operating life of a system here, and a contractor who ignores it when selecting equipment capacity, specifying refrigerant line lengths, or evaluating the installation site is quoting for a different county. The load is standing, and the install has to be built for it.
Ductwork laid down for a furnace and nothing else was sized, routed, and sealed for a different job than central air asks of it. Half the homes in Mineral County, West Virginia were built in 1977 or earlier (2020-2024 ACS 5-year). A contractor installing central AC in a house of that vintage has to assess whether the existing trunk lines and branch runs can actually move the volume of air a modern cooling system needs, and whether the electrical service will carry the new load. Those two questions, answered from what is physically in the house, are what a quote here is built on.
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 together shed heat pulled from inside. The indoor 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 the homeowner sets and reads temperatures. Refrigerant lines run between the outdoor and indoor units, and a condensate drain line carries moisture pulled from the air to a floor drain or outside the house.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific house and setup.

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.
