AC installation cost by system.
Installed pricing for Brookhaven, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Brookhaven, Georgia, a typical AC installation costs between $4,400 and $14,300+, depending on system type and ductwork needs. With a median home age of 35 years and high cooling demand in this hot-humid climate, many homeowners replace older central ACs or upgrade to heat pumps. Georgia requires a mechanical permit and licensed contractor for installations, and while Manual J/S sizing is recommended, it's not strictly enforced on changeouts. Federal tax credits (30% up to $2,000 for heat pumps, $600 for high-efficiency AC) can offset costs. Given the mixed heating needs, a heat pump is a strong fit for Brookhaven homes.
