    Some methods that companies using involve using a tool called a wire duct brush. This can be used as an electric power tool. If the operator of the tool is not careful this can damage the interior of the ductwork.

    They may not realize they caused damage right away.

    This can actually lead to mold and I will include a real-life story where that very issue occurred for me:

    The client noticed that there was some possible mold present in one of the bedroom closets. During a mold inspection, clues led me to the attic space above. When I got in the attic, there was an odor present and visible mold on some of the structural wood. There was also condensation on the exterior insulation of the ductwork. As I was crawling through the attic, I suddenly felt cold air.


    The mixture of cold air leaking from the ductwork and hot air in the attic space led to condensation and mold growth. Mold was also growing within the inner walls of the closet below.

    Oh, and the company that did the duct cleaning accepted no responsibility and last I heard there was a lawsuit still pending.

    Bottom line:

    Damage can not only lead to monetary responsibility but can also cause mold.
