Which entity completes and documents the test and balance work during Construction HVAC Commissioning?

• A. TAB Agency
• B. The Owner
• C. The Architect
• D. The CxA

Answer: (A)

Testing, adjusting, and balancing HVAC systems is done by a TAB agency—the firm that specializes in measuring airflow, damper positions, and system pressures and then balancing the system to the design values. They bring the calibrated instruments, perform the actual measurements, and generate the TAB report that documents the as-installed conditions, required adjustments, and final operating parameters. The commissioning authority oversees the process, reviews the TAB results, and ensures the documentation is incorporated into the project record, but the hands-on TAB work and the official TAB documentation come from the TAB agency. The owner and architect are stakeholders who review and use the results, while the CxA coordinates and verifies the process.
