The National Air Duct Cleaners Association is celebrating 25 years at its convention this month.

The group, which likes to point out that it does much more than just clean ducts these days, will be visiting the Grand Hyatt in San Antonio March 3-6. Besides a trade show, organizers this year have divided sessions into industry education and business tracks. The association will also celebrate a quarter century in business with “A Celebration of NADCA” at 10:30 a.m. March 5 hosted by longtime NADCA member Tom Yacobellis of Ductz International.

Another highlight will be “Recent Developments in Employee Law,” hosted by lawyer Steve Roppolo of Fisher & Phillips. Roppolo draw on his decades of experience to tell members the latest on worker laws and how they may impact NADCA members.

A history of efforts to improve indoor air quality will be presented by Richard Shaughnessy of the University of Tulsa at 8 a.m. March 6.

The world of Internet marketing will be explained by Bob Krell of IAQ Technologies during “Indoor Environments, Consumers, Industry Professionals and How Social Media and the Internet Connects Them”  at 4:15 p.m. March 6.
