National Air Duct Cleaners Association

The National Air Duct Cleaners Association (NADCA) was formed in 1989 as a non-profit association of companies engaged in the cleaning of HVAC systems. Its mission was 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. The goal of the association is to be the number one source for the HVAC cleaning and restoration services: first time, every time.
NADCA has experienced phenomenal membership growth and has been extremely successful with the training and certification of air systems cleaning specialists, mold remediators, and HVAC inspectors. The association has also published important standards and guidelines, educational materials, and other useful information for the consumer and members of NADCA.
Today, NADCA standards and certification are specified on a regular basis to ensure that HVAC systems are assessed, cleaned, and restored in a safe and efficient manner.

HVAC system cleaning is the process by which heating, air conditioning, and ventilation systems are cleaned to remove excessive accumulations of dust, debris, and biological contaminants. With heightened public awareness of the dangers of indoor air pollution and the need for home energy efficiency, the demand for professional HVAC system cleaning has increased dramatically.
