One of the most common questions we are asked by prospective air duct cleaning customers is should the air ducts be “sanitized” after cleaning. Often times during their search for an air duct cleaning contractor, customers speak to companies who insist that the air ducts be sanitized after cleaning. Since the contractors are viewed as experts, they believe this is a necessary step in the cleaning process.

The reality is, the vast majority of homes and businesses do not need their air ducts sanitized after the ducts are cleaned. In fact, the National Air Duct Cleaner’s Association (NADCA), says the best method for cleaning and decontaminating air ducts is to use the source removal cleaning method. Complete HVAC system cleaning removes the contaminants that may contribute to mold and other microbiological growth (NADCA). NADCA also states that it is not necessary to apply chemicals as part of the source removal cleaning process.
