Awareness of indoor air quality has increased substantially in recent years, and the systems that supply air to our living and working spaces are critical to the maintenance of a healthy indoor environment. 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.
The EPA are particularly concerned about the use of Disinfectants and Sanitizers in Heating, Ventilation, Air Conditioning Systems because the Agency has not assessed the potential exposure and risks to building occupants or applicators from the use of these products in or on any surfaces that are part of HVAC&R systems in circumstances where the labels do not specifically authorize use in HVAC&R systems. Also, the Agency has not assessed whether such products are efficacious when used in HVAC&R systems. Therefore, users cannot assume that EPA registration of these products reflects any conclusions about their safety or effectiveness in this situation. Consumers should familiarize themselves with the NADCA POSITION PAPER on Chemical Product Applications in HVAC Systems prior to allowing the use of chemicals in the HVAC system.
Products used as foggers to kill or control microbial growth inside air conveyance systems should only be applied to sheet metal ductwork.
Sanitizer should be applied in accordance with the manufactures instructions and ever be applied without the use of proper respiratory protection for applicators.
