On this project, Duct & Vent Cleaning of America, Inc contact HEPA vacuumed one roof-top air handling unit, all of the ductwork, diffusers/grills that service the men's security locker room at the Stamford Train Station. After HEPA vacuuming, we coated the internally lined ductwork up on the mezzanine with IAQ 8500 duct liner HVAC Sealant to regain the integrity of the old deteriorating internal insulation.
