NADCA is the National Air Duct Cleaners Association

NATIONAL AIR DUCT CLEANERS ASSOCIATIONNADCA  was formed in 1989 as a not for profit association based in Washington DC. Its mission is to promote source removal as the only acceptable method of cleaning and to establish industry standards for the association. NADCA has expanded its mission to include the representation of qualified companies engaged in the assessment, cleaning, and restoration of HVAC systems, and to assist its members in providing high quality service to their customers. Over the years NADCA has brought forth guidelines such as ACR 2006 (Assessment, Cleaning and Restoration of HVAC systems), which has been adopted by most engineering firms as the standard for duct cleaning procedure.

In order to become a National Air Duct Cleaners Association certified technician, an ASCS (Air Systems Cleaning Specialist), a technician must demonstrate knowledge of HVAC system cleaning, NADCA standards, OSHA regulations and pass a 150 question exam. The ASCS is a continuing education based certification, so each year a technician is required to earn 6 continuing education credits during the past year, which may be obtained through attendance at NADCA seminars and conventions, online renewal quizzes, publication of technical papers in industry journals, attending related industry training programs, and a variety of other means. NADCA holds numerous training seminars and meetings on new regulations being brought forth into the duct cleaning industry. NADCA is the only regulatory body in place to ensure that when a customer contracts a duct cleaning, they will deal with a trained, qualified professional. To date there is no other licensing body for air duct cleaners.
