AABC establishes industry standards for Total System Balance of building environments, and is the only association that exclusively certifies independent agencies.

As the complexity of HVAC systems began to increase in the 1960s, a small group of engineers founded the Associated Air Balance Council (AABC) as a non-profit association in 1965. Early on, they recognized the need for independence and stringent membership requirements to ensure objectivity, integrity, and technical expertise, and they made these the guiding principles of the association. AABC also developed the first comprehensive industry standards for test and balance.
