Our team has seen a variety of interesting home fixes for dirty air ducts. At a residence in Olney, MD, a homeowner attempted to wrap register filters on her floor boots after seeing “black stuff” in her air ducts. The fungus persisted and continued to grow on the filters. For professional duct cleaning, Quality Air Solutions uses top rated abatement technologies which are approved by the National Air Duct Cleaning Association.
