Should I have my ducts cleaned?

The industry is evenly split on this topic. Some consultants recommend cleaning of the duct system after remediation of any mold in your home, others believe that the ducts should never be cleaned. Pacific IAQ falls somewhere in between. We believe that actual mold growth in rigid ducts can be successfully cleaned, but mold growth in the flexible ducts is not practical or possible. Pacific IAQ recommends that flexible ducting that has actual mold growth inside should be replaced. If the ducts, flexible or rigid, are contaminated with mold spores due to an elevation somewhere in the home that has traveled through the duct system, then duct cleaning may offer some benefit. In either case it is recommended that the duct cleaning should be done by a NADCA certified duct cleaner.
