National Air Balance Inc.

National Air Balance Inc. Specializing in air systems balancing, hydronics balancing, duct leakage testing and more. National Air Balance was incorporated in February of 1973.

Since that time we have become a name synonymous with proper inspecting, accurate testing and professional conduct. This high level of respect was earned by the employment of top level technologists, who insist on maintaining the high quality standards expected of them. Our balancing procedures are equivalent to, or are surpassing the methods and standards introduced by A.S.H.R.A.E. (American Soci

ety of Heating, Refrigeration and Air Conditioning Engineers). In addition to our 12 month customer warranty, quality workmanship and total customer satisfaction are further guaranteed by the National Building Comfort Testing Association (NBCTA) An organization that we have been a founding member of for over forty years. We feel we can offer you far superior service than can be obtained elsewhere, as our firm is proud to be second to none in our field. Our most recent large projects we have successfully completed is the Cambridge Memorial Hospital, and Ashbridges Bay Water Treatment Plant in Toronto, Ontario. In today’s growing green market, National Air Balance is a proud member of the Canada Green Building Council (CaGBC) which is a non-profit national organization dedicated to working with government and the private sector to accelerate the "mainstream adoption of green building principles, policies, practices, standards and tools."
