For instance, if you spot a vermin infestation such as insects and rodents, it may be necessary for you to embark on air duct cleaning g to get rid of them and the mess they might have created within the forced air system. Consequently, if you spot any kind of mold growth along the air duct or other parts of the cooling or heating system, it might also necessitate air duct cleaning. Insulated air ducts can be coated with moldy or wet insulation since such cannot be effectively cleaned and might call for the removal of the entire air duct and replacement.
