Air duct cleaning will remove visible mold inside air ducts, but that won't stop mold from growing back. In order to remediate mold in air ducts, you have to make sure the source of water that allowed mold to grow is repaired. In this way, the air duct cleaning will be more effective. In certain cases, we also recommend using special chemicals in the ducts to prevent future mold growth.
