A contractor sizing central AC here starts from the house itself: its square footage, insulation, window exposure, and how air actually moves through the rooms. 100 severe weather events were recorded in Morgan County, West Virginia between 2015 and 2024. At that rate, severe weather is a real but not dominant factor in how hard a system will run, which means the install itself carries most of the weight. Ductwork that leaks, a unit set one size too large, or refrigerant lines run without proper support will underperform regardless of what the sky does. The local weather record shapes the calculation; the quality of the contractor's work determines what the homeowner gets.
Ductwork put in for an older system carries assumptions about airflow that a new central AC unit may not share, and that gap is where a Morgan County installation job gets decided. Half the homes in Morgan County, West Virginia were built in 1987 or earlier (2020-2024 ACS 5-year). A contractor sizing new equipment here checks whether the existing duct layout moves air the way the new system needs before anything else gets priced. If the runs are undersized or the returns are too few, the equipment choice becomes secondary to what the house already has inside its walls.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a 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, closet, or attic and contains the evaporator coil and blower fan that push conditioned air into the home.
A metering device, often a small expansion valve, connects the indoor and outdoor sections and controls refrigerant flow between them. The thermostat goes on an interior wall and is the control point a homeowner interacts with every day, telling the system when to run and when to stop.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies 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.
