NBC Philosophy

​

The distinguishing characteristic of an NBC certified supervisor or technician is the ability to prescribe solutions to the endless field conditions that prohibit an HVAC system from achieving balance and maximum field performance. Nearly all NBC technicians have extensive field experience in HVAC system repair, installation or service and possess skills required to troubleshoot the most difficult field conditions that can be revealed by their testing. These technicians test, diagnose and maximize the performance of over 200,00 HVAC systems per year.

​

Practical Standards

​

Each certified supervisor and technician prescribes to National Balancing Council Practical Standards and Procedures. These cover a full range of testing, balancing, adjusting, and diagnostic practices backed up by NBC Reporting forms.

​

​

CSER and HSER

​

In addition to traditional independent test reports, NBC technicians can provide an efficiency rating of the installed system. These ratings can be compared to manufacturer's equipment efficiency ratings to offer a new view of system performance that is not offered anywhere else in the HVAC industry. CSER represents Cooling System Efficiency Rating and HSER is Heating System Efficiency Rating.
