The ductChallenge online program allows the user to test drive and see the difference between the company’s custom manifolded duct and another manufacturer’s stock duct. At the company’s Website, the user can assemble two duct systems at a virtual jobsite, then review the time and money differences between the stock and the custom ductwork. The ductChallenge is an online version of an installation competition the company held.
