​"Established in 1971, the National Environmental Balancing Bureau (NEBB) is the premier international certification association for firms that deliver high performance building systems." ​

Testing, Adjusting, and Balancing

TAB is one of seven disciplines and firms included in the NEBB. TAB stands for testing, adjusting, and balancing - these are the three major steps to achieve proper operation of HVAC and Hydronic systems. TAB  is essential to optimal environmental performance in buildings, as well as aiding in the effort to lower the operating cost of the systems. When buildings invest in quality testing, adjusting, and balancing for the HVAC and Hydronic systems, these goals are accomplished. 
Mullinax TAB, Inc. is a certified, professional business through the NEBB. We only use the best and most up-to-date instruments for testing, adjusting, and balancing. When you partner with us to do a job, our team will:
  1. ​Develop and plan the work
  2. Handle report preparation
  3. Recommend corrective action
  4. Set overall safety plan
  5. Maintain instruments and calibration program
  6. Have experience with control strategies, sequence of operation, control systems, equipment and software
  7. Review, check, sign, and stamp final TAB report

Testing

Testing is the use of specialized and calibrated instruments to measure temperatures, pressures, rotational speeds, electrical characteristics, velocities, and air and water quantities for an evaluation of equipment and system performance. 

Adjusting

Adjusting is the final setting of balancing devices such as dampers and valves, adjusting fan speeds and pump impeller sizes, in addition to automatic control devices such as thermostats and pressure controllers to achieve maximum specified system performance and efficiency during normal operation.

Balancing 

Balancing is the methodical regulation of system fluid flows (air or water) through the use of acceptable procedures to achieve the desired or specified airflow or water flow.
