The National Air Duct Cleaners Association (NADCA) is a non-profit organization committed to publishing standards for safety, evaluation, and cleaning of heating, ventilation, and air conditioning (HVAC) ducts. They also offer several certifications for HVAC companies and professionals, as well as maintain an anti-fraud task force.
The Division of Occupational Safety and Health of the United States Department of Labor recommends hiring only duct cleaning professionals who are NADCA members.

History
The NADCA was founded in 1989 when Pringle Power Vac owner John Sumerlin gathered 25 HVAC professionals to discuss the professional duct cleaning industry.
Founded to promote the source removal method of duct cleaning and the establishment of industry standards, the NADCA currently offers training courses, publishes standards, provides professional resources, maintains an HVAC professional locator tool, and more.
The NADCA first published a standard, "Standard 1992-01, Mechanical Cleaning of Non-Porous Air Conveyance System Components," in 1992. They currently publish "Standard for the Assessment, Cleaning, and Restoration of HVAC Systems," called ACR: the NADCA Standard. The ACR provides guidelines for assessing HVAC systems, evaluating cleanliness, preventing hazards, cleaning methods, and cleaning equipment.
Presently, the members of the NADCA are over 1,000 HVAC cleaning companies with one or more certified ASCS technicians.

Certification
In 1995, the NADCA began their first certification program, administering examinations for Air Systems Cleaning Specialist (ASCS) in Baltimore, Atlanta, Chicago, Dallas, and Los Angeles.
In 2003, they launched a Ventilation System Mold Remediator (VSMR) training and certification program, as well as a Certified Ventilation Inspector (CVI) training and certification program.
In 2013 NADCA decided to combine the ASCS and VSMR certifications into one certification, the ASCS. The present ASCS course has been revised to include the necessary VSMR training.
The ASCS and CVI programs are currently being offered.
