Duct Debris. A closer look.
I am continuously shocked at the amount of dust and sediment that I pull from ductwork every day. Just to give you an idea of what I see and experience when cleaning ducts, I've attached a GoPro camera to the end of our whip while cleaning a recent building.
To be forewarned, dust and any contaminants are captured safely in a 5000cfm Hepa negative air machine. This ensures that nothing we pull out of the system is redistributed throughout the building.
