Here is an example of ductwork that has been damaged by moisture. Over time, the ductwork will begin to rust and eventually collapse in some areas. Also, mold and other bacteria can form in these ideal conditions causing odors and unhealthy air.
Here is the same ductwork, as seen before, completely encapsulated with Duct Armor. Not only is the rust coated, but the natural inhibitors in Duct Armor will prevent mold and other allergens into your home. You can have piece of mind knowing that your house will have healthy and clean air for years to come.
