A contractor quoting a central AC installation in Augusta County has to account for a climate that pushes equipment hard on a regular basis. 190 severe weather events were recorded in Augusta County, Virginia between 2015 and 2024. At that rate, severe weather is a standing condition for every system in the county, which means the sizing decisions and installation choices a contractor makes here carry real consequences. A unit built to minimum spec for a gentler region will be undersized against what Augusta County actually asks of it. Contractors who know this area spec accordingly from the start.
Existing ductwork is what a contractor prices around on a central AC installation here, and whether it moves enough air for a modern unit is something you find out by measuring, not by looking at how the house was built. Half the homes in Augusta County, Virginia were built in 1989 or earlier (2020-2024 ACS 5-year). That gap between when the framing went up and what runs in it now means duct sizing that made sense for the original equipment often falls short for a new system, and a contractor who does not assess it before quoting is skipping the step that changes the bill. The electrical is a separate check, but the ductwork is where Augusta County installations tend to go one way or the other.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a pad outside the house and holds the compressor and condenser coil, which do the core work of the system. Inside, the air handler or furnace-and-coil assembly mounts in a utility space, a closet, or an attic, pulling household air across the coil before pushing it back through the home.
The thermostat goes on an interior wall where it reads the air temperature and tells the system when to run. A refrigerant line set runs between the outdoor and indoor units, and a condensate drain line carries moisture pulled from the air out of the house.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.

What HVAC Installation Looks Like in Augusta 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.
