Standard addresses assessment, cleaning and restoration of HVAC systems
The National Air Duct Cleaners Association (NADCA) has released its 2021 edition of ACR, the NADCA Standard for the assessment, cleaning and restoration of HVAC systems. The document reflects necessary updates to the standard after new testing was conducted by EMSL Laboratories.
The ACR is an international standard that defines the minimum performance and procedural requirements for air duct cleaning. It includes practical, industry-backed information for assessing new and existing HVAC systems, evaluating and verifying the cleanliness of HVAC system components, preventing job-related hazards such as exposure to workers and occupants and cross-contamination of the indoor environment, and guiding the cleaning and restoration of HVAC systems to a specific level of cleanliness.
