Testing, Adjusting & Balancing (ANSI)

Testing: to determine qualitative performance of equipment.

Adjusting: to regulate the specified fluid flow rate and air patterns at the terminal equipment.

Balancing: to proportion flows within the distribution system according to the specified design quantities.


Testing, adjusting and balancing, all HVAC systems in a new building is needed to complete the installation and to make the system perform as the designer intended.

Assuming that the system design and installation meets the comfort needs of the building occupants, good testing, adjusting, and balancing of the HVAC system provides occupant comfort with minimal energy input. This is extremely important in the era of rising energy costs.

The testing adjusting and balancing or TAB phase of any building construction or renovation is intended to verify that all HVAC water and air flows and pressures meet the design intent and equipment manufacturers operating requirements. It is rare to find an HVAC system of any size that will perform completely satisfactorily without the benefit of TAB.

ICB/TABB report ensures that HVAC systems operate at the highest standards of energy efficiency and ventilation effectiveness. ICB/TABB-Certified Professionals are recognized as the most competent, reliable and qualified in the HVAC industry.
