Sizing a central AC system in Wood County is not a question a contractor can answer from a catalog. 135 severe weather events were recorded in Wood County, West Virginia between 2015 and 2024. At that rate, severe weather is a regular feature of what equipment here runs against, and a system sized for moderate demand will be undersized for the load this area actually puts on it. A contractor working an install in this county factors that pressure into both equipment selection and the quality of the refrigerant lines, because those are the points where a strained system shows it first.
Ductwork sized and routed for a different era of equipment is what a contractor has to assess before anything else gets priced on an installation job here. Half the homes in Wood County, West Virginia were built in 1970 or earlier (2020-2024 ACS 5-year). That gap between when the house was framed and what a new central AC system demands from its distribution is where installations either stay on budget or do not. If the existing trunk lines and branch runs can move the volume a modern unit pushes, the install is clean. If they cannot, the ductwork becomes a separate scope before the electrical service for the new equipment is even opened.
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 work in the system. Inside, the 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 it reads the temperature of the living space and tells the system when to run. A contractor also installs the copper refrigerant lines that run between the outdoor and indoor units, and the condensate drain line that carries moisture away from the air handler.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific house.

What Happens During an HVAC Installation in Wood 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 Wood County
Weather puts direct load on cooling equipment, and that load is shaped by local conditions. What Wood County sees year over year determines how hard a central AC system has to work and what it needs to be sized and installed to handle.
