In 1961, Nap Estes, Charlie Wright, and a group of individuals initiated MAACA. Their gatherings, convened monthly over lunch, were dedicated to delving into HVAC matters within metro Atlanta. In 1980, Earl Smith and fellow Carrier dealers established CAAG across the state, with MAACA swiftly aligning as one of its inaugural chapters. To this day, MAACA proudly stands as Georgia's oldest CAAG chapter.
