NADCA: The HVAC Inspection, Cleaning and Restoration Association, otherwise known as the National Air Duct Cleaners Association (NADCA), was formed in 1989 as a nonprofit association of companies engaged in the cleaning of HVAC systems. Its original mission was to promote source removal as the only acceptable method of cleaning and to establish industry standards for the association.

NADCA’s mission has expanded to include qualified companies engaged in the inspection, cleaning and restoration of HVAC systems. NADCA supports members' success with standards, education, certification, marketing and advocacy to promote ethics and the highest quality services. The goal of the association is for its members to be the number one resource for consumers and other entities seeking air duct cleaning and HVAC inspection, cleaning and restoration.

NADCA’s membership continues to grow each year, along with its training, education and certification opportunities for air systems cleaning specialists, mold remediators, HVAC inspectors and others. The NADCA has also published industry standards, educational materials and other useful information for consumers and members alike.
