As the global industry's leading advocate and trusted resource for reliable information, the National Air Duct Cleaners Association (NADCA) is uniquely qualified to provide guidance for consumers and the industry on the best practices for inspecting, cleaning and restoring HVAC systems. Source removal of contaminants remains the single best method for cleaning and decontaminating HVAC systems. However, HVAC systems sometimes require treatment for odors or the reduction of microbial contamination. One remedy that has been used for these problems is ozone, a form of oxygen. Currently a broad range of information exists regarding the use and efficacy of ozone. In working with all parties associated with indoor air quality, NADCA recognizes the need to provide direction in this area. Although the following information reflects the current state of the art for the use of ozone in HVAC systems, readers should recognize that new developments regularly occur and should familiarize themselves with the most current information when determining the appropriate steps to take. Disclaimer NADCA recognizes that differences in opinion will exist as to how to manage the use of ozone. NADCA also recognizes that industry professionals will decide whether or not the application of ozone is appropriate for a given HVAC system, based on the unique circumstances surrounding that system. Ultimately, the decision of whether or not to apply ozone to an HVAC system rests with the owner of the system.
