Frequently Asked Questions

What is TAB? TAB stands for testing, adjusting and balancing of your environmental systems and compressors. The testing part includes the use of specialized equipment to take precise measurements of how your system is operating. 

Testing, Adjusting, and Balancing is a vital step for complex air and hydronic systems within buildings and throughout campuses to ensure HVAC systems are optimized for occupant comfort, energy efficiency, indoor air quality, and manufacturing processes.

First, locate the closest supply air duct to your indoor AC unit. Then use a thermometer, even a refrigerator thermometer will work, and tape it just inside. Let your Air Conditioning run for about ten minutes then check and record the temperature.
