HVAC Testing, Adjusting and Air Balancing (TAB) are the three major steps used to achieve proper operation of HVAC (heating, ventilation, and air conditioning) systems. The NCI Certified Air Balance insures that all components of the HVAC system are working in harmony, at their optimum performance, providing total occupant comfort. During this process, a mechanical engineer develops specifications and a set of mechanical drawings from a mix of occupant desires, local codes, ASHRAE standards,and many years of training.
Testing, adjusting, and balancing of all HVAC systems in a new building is needed to complete the installation and to make the system perform as the designer intended. The purpose of testing, adjusting, and balancing (TAB) is to assure that an HVAC system is providing maximum occupant comfort at the lowest energy cost possible. This is extremely important in this era of rising energy costs. Most new commercial projects require a licensed air balancing report before they are able to receive a certificate of occupancy.
