AC installation cost by system.
Installed pricing for West Falls Church, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In West Falls Church, Virginia, the median home was built in 1962, so many homes need AC installation due to aging or undersized equipment. Typical local costs for a like-for-like central AC replacement range from $4,000 to $8,100+, while a new system with ductwork runs $6,100 to $13,200+. Ductless mini-splits and heat pumps are also common, with heat pumps qualifying for a federal 25C tax credit of up to $2,000. Virginia requires a mechanical permit for any AC installation, and the Uniform Statewide Building Code (USBC) applies. Manual J/S load calculations are recommended to ensure proper sizing, especially for older homes. The mixed-humid climate means moderate cooling demand, making a heat pump a strong fit for year-round comfort.
