Sizing a central AC system here starts with what the local climate actually asks of it. 161 severe weather events were recorded in Monongalia County, West Virginia between 2015 and 2024. At that rate, severe weather is part of the normal working life of any system in this county, and a contractor has to account for it before settling on equipment capacity, refrigerant line routing, or how tightly the air handler is sealed. A unit specced for mild conditions will run longer cycles, strain its compressor earlier, and cool unevenly. The install decisions that look like details on paper are the ones that decide how the system performs when the weather pushes hardest.
Ductwork laid in for a furnace and later asked to move conditioned air for cooling is often the tightest constraint a contractor encounters on an installation job here. Half the homes in Monongalia County, West Virginia were built in 1988 or earlier (2020-2024 ACS 5-year). That puts a large share of the county's homes in a range where the ducts were designed around a different kind of system entirely, and a contractor has to assess whether what is in the walls will actually deliver the airflow a new central unit needs before the equipment choice matters at all. The electrical service gets the same look, since a panel from that era may need an upgrade to handle a modern condenser's draw.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad outside the house and holds the compressor and condenser coil, the hardware that does the heaviest mechanical work in the system. Inside, the air handler or furnace-based evaporator coil sits in a closet, attic, or basement and is the point where conditioned air enters the duct system.
The thermostat goes on an interior wall where it reads the air temperature of the living space and signals the rest of the system to run or stop. A contractor also installs the refrigerant line set, a pair of copper lines that run between the indoor and outdoor units and carry the refrigerant that ties both sides together.
The drawing shows the typical layout of these components, and a licensed contractor determines exactly how they fit into your specific home.

What HVAC Installation Looks Like in Monongalia 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.
