Is duct work sanitizing a good idea?
Many clients ask about the application of a santizing chemical as a normal function while cleaning ductwork. And some duct cleaning contractors routinely offer sanitizing for free. If microbial growth is suspected in a duct system, Americlean recommends a micro-biologist perform testing. The application of a sanitizing agent is not recommended as a general practice unless microbial growth is visually evident or a professional biological assessment has been performed. Sanitizing agents applied to the interior of a duct system must be registered with the EPA because these chemicals are classified as pesticides (toxic chemicals).Dust in a duct system consists predominantely of organic based matter. This is a nutrient source for biological growth and sustenance. If the food source is removed by professional cleaning methods the application of a sanitizer as a precautionary measure is redundant.
