What does TAB stand for?

• A. Test and Balance Contractor
• B. Technical Assessment Board
• C. Testing and Building
• D. Total Annual Balance

Answer: (A)

In building commissioning and HVAC, TAB refers to the testing and balancing work done on a system, usually carried out by a TAB contractor—the firm that performs the testing, measurements, and balancing to ensure airflow, pressures, and temperatures align with the design. That’s why the option “Test and Balance Contractor” fits best here: it reflects the common way TAB is used to name the party responsible for performing those tasks. While the actual process is called Test and Balance, the exam often emphasizes the contractor role to identify who implements that work. The other phrases don’t match standard industry usage.
