A contractor sizing and installing central AC in Craig County has to account for what the local climate actually demands, not what a worse region might. 47 severe weather events were recorded in Craig County, Virginia between 2015 and 2024. At that rate, severe weather lands on the area as an event, not a constant pressure, and a system that was correctly sized and properly installed handles it without incident. What a contractor quotes on and what they flag as risk here comes down to installation quality, duct layout, and equipment match to the structure. Those are the variables that determine how a system performs across its life in this county.
Ductwork sized and routed for the systems that came with these houses carries real weight in any installation quote. Half the homes in Craig County, Virginia were built in 1981 or earlier (2020-2024 ACS 5-year). That gap between the building and what runs in it now is where a contractor spends most of their assessment time, checking whether existing ducts can move the volume a new central AC unit requires and whether the electrical service will support the load. If the ductwork falls short, the scope of work changes before the equipment is ever selected.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and holds the compressor and the condenser coil. Inside, the air handler or furnace blower sits in a utility closet, basement, or attic and pushes conditioned air through the home. These two units are the core of what a contractor puts in.
A copper refrigerant line set runs between the outdoor and indoor units, connecting them through a wall or floor penetration. The thermostat goes on an interior wall and gives the homeowner control over the whole system. A condensate drain line also runs from the air handler to carry away the moisture the indoor coil pulls from the air.
The drawing shows the general layout of a central AC system, and a licensed contractor determines exactly how each piece fits the conditions of your house.

What HVAC Installation Looks Like in Craig 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.
