TAB stands for which term in HVAC terminology?

• A. Test and Balance
• B. Testing, Adjusting, and Balancing
• C. Testing And Balancing
• D. Thermal Air Balancing

Answer: (B)

TAB stands for Testing, Adjusting, and Balancing. This name reflects the full process used in HVAC commissioning: you test the system to measure how it’s performing, adjust components such as dampers, VAV boxes, and fans to meet the design goals, and then balance the airflow so each zone gets the intended amount of air. That combination is essential because simply testing and balancing omits the crucial step of making adjustments to achieve the required performance. The other options either omit Adjusting or use a misrepresentative term, so they don’t capture the complete process the acronym represents.
