HVAC Installation in Atlanta, GA

Replacing an HVAC system in Atlanta requires careful sizing for the region's long cooling season and occasional hard winter freezes. A proper Manual J load calculation is essential — oversized systems short-cycle and leave homes humid and uncomfortable, while undersized units struggle through Georgia's peak summer heat. Georgia-licensed HVAC contractors in Atlanta install central air conditioning, heat pumps, gas furnaces, and ductless mini-split systems. New system costs range from $5,000 for a basic single-zone replacement to $15,000+ for premium two-stage or variable-speed systems. All installation work requires a mechanical permit from the local jurisdiction. The contractors below hold Georgia conditioned air licenses and serve Atlanta neighborhoods and suburbs including Buckhead, Sandy Springs, Marietta, Smyrna, and Decatur.
