NBC-affiliated firms in the U.S. and around the world provide unparalleled testing, adjusting, and balancing services on commercial air and hydronic HVACR systems on projects of all sizes and scope. NBC Certified Supervisors and Technicians also provide expert system commissioning and re-commissioning.
NBC has established and maintains stringent standards that must be met by those seeking to qualify for certification. Engineers, contractors, building owners, and property managers can be assured every NBC-certified professional is required to complete a rigorous training program, and to successfully pass a comprehensive examination process prior to receiving his or her credentials.
NBC has developed over 60 practical testing and balancing procedures that certified professionals employ in the field. These practical standards ensure systems will be tested and balanced with integrity, accuracy, and, most critically, repeatability of the test results.
Below is a partial list of available procedures:
NBC was established in 2006 as the commercial-industrial division of National Comfort Institute, Inc. (NCI). NCI was established in 1993 and began training HVAC contractors, service technicians, installers, and engineers in TAB and system diagnostics. Initially focusing on residential and light commercial systems, NCI has trained and certified nearly 20,000 people in the U.S. and 10 other countries. With the success of NCI came the demand for a higher level of TAB training and certification. To meet these needs, the National Balancing Institute (NBI) was established and subsequently evolved into NBC.
