The Associated Air Balance Council (AABC) is a group of testing, adjusting and balancing (TAB) professionals that establishes industry standards for Total System Balance of building environments, and is the only association that exclusively certifies independent agencies.
Independence is the cornerstone of AABC; members are strictly prohibited from having any affiliations with mechanical contractors, design engineers, or equipment manufacturers. This policy prevents any potential conflicts of interest and ensures that all members provide engineers and building owners with professional, unbiased TAB services.
AABC was established in 1965 by a small group of engineers who realized the increasing complexity of HVAC systems. 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.
