Testing, Adjusting, and Balancing (TAB) involves measuring and adjusting air and water flows to meet design requirements. The TAB process is comprised of using test instruments, sensors and monitors to verify appropriate temperatures, airflow and other characteristics within the HVAC system.

TAB technicians make sure that air and water in heating and air conditioning systems are delivered efficiently, quietly and safely throughout a building. As a TAB technician, you will be responsible for working on air and water delivery systems to meet the specifications outlined by the design engineer.

In summary, TAB is a meticulous and essential procedure that ensures HVAC systems perform optimally, delivering the desired indoor environment while minimizing energy usage and operational costs. It plays a pivotal role in the broader context of system commissioning, making it a cornerstone of the HVAC industry.

PACE Collaborative provides pre-construction or pre-design analytical testing of existing HVAC systems widely known in the construction industry as pre-TAB (preliminary Testing, Adjusting, and Balancing). Although pre-TAB is the incorrect terminology to use, it is easier to articulate.
