Arizonians are real aware of how dusty it is here. With the sandy dirt, to our haboobs, dust is a way of life. Add to the equation our hot summers and the HVAC working around the clock, those ducts fill up with dust, debris, and sometimes mold. At DUCK, I always clean each duct line in its entirety, all the way back to the handler, never doing partial jobs. I then finish each job by spraying each duct line with a microbial disinfectant removing any final contaminants.
