We completely clean out moldy duct work
Moldy Duct Work in Chattanooga Home
When air ducts are dirty the whole home will be dirty. Too much dirt in an air duct is the reason for the mold. If the ducts are clean then the little moisture when turning on the A/C or Heat will not be a problem.
However, these air ducts were incredibly dirty which allowed the mold enough organic material to take root and start to grow. The added moisture and mold spores created a huge mess that needed to be cleaned.
The second picture is what the register looked like after our fist cleaning. It needed two deep cleaning runs to assure no more dirt and mold were in the duct system.
