What kind of equipment?*

Sizing a central AC system in Boone County starts with what the climate actually asks of it. 120 severe weather events were recorded in Boone County, West Virginia between 2015 and 2024. At that rate, severe weather is part of the normal working life of any system installed here, which is why a contractor quotes and sizes for local conditions rather than pulling a spec from a catalog. Duct layout, equipment capacity, and the quality of every connection matter more when the system will run hard for years against a climate like this one.

Ductwork laid in for a furnace handles airflow differently than what a central AC system wants. Half the homes in Boone County, West Virginia were built in 1976 or earlier (2020-2024 ACS 5-year). That gap between the original design and what a new cooling unit needs to move air is where a contractor spends real time during an installation quote, checking whether the existing runs, sizing, and return paths will carry the load. The electrical is the other variable: panels from that era were sized for what those houses ran then, and a new AC unit draws more than that original estimate counted on.

What Gets Installed With a New Central AC

The outdoor condenser unit sits outside the house, usually on a concrete pad along a side or rear wall, and holds the compressor and condenser coil. Inside, the air handler mounts in a utility closet, attic, or basement and pushes conditioned air through the home. Together these two units form the core of what a contractor puts in place.

The refrigerant line set runs between the outdoor and indoor units, connecting them through a small penetration in the wall. A thermostat goes on an interior wall where it can read the home's air accurately, and the contractor ties the whole system into the existing electrical supply at a dedicated circuit.

The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.
