What is the formal term for the systematic process applied to HVAC systems to determine and document air and hydronic flow rates?

• A. Testing, Adjusting and Balancing (TAB)
• B. Troubleshooting
• C. Zone
• D. Velocity

Answer: (A)

The formal term for the systematic process used to determine and document air and hydronic flow rates in HVAC systems is Testing, Adjusting and Balancing. This approach involves measuring actual flows, pressures, and velocities, then adjusting dampers, valves, and other control devices so each space receives the design amount of air and water. The results are documented in a TAB report, which confirms that the system meets the design intent, supports occupant comfort, and operates efficiently. This differs from Troubleshooting, which focuses on identifying and fixing faults; a Zone is simply a control area or grouping of spaces; and Velocity is the speed of air, not the full process of measuring, adjusting, and recording system flows.
