      Why AABC?

      Independence

      AABC is the only TAB certifying organization that prohibits its members from having any affiliation with mechanical contractors, design engineers, or equipment manufacturers. This prevents conflicts of interest and ensures that engineers and building owners get objective, unbiased test and balance services.

      Guaranty

      All projects completed by AABC members are covered by the National Performance Guaranty, providing assurance that your project will be completed in accordance with the AABC National Standards and the project specifications.

      Quality

      AABC members meet the industry’s highest certification standards and are pledged to provide the highest quality TAB services to ensure proper system performance. AABC monitors the performance of member agencies through its quality assurance program.

      History

      Founded in 1965, AABC was the original test and balance organization and remains the most widely respected today. More than 50 years later, no one has matched its commitment to independence, integrity, and technical excellence.
