NADCA Debuts HVAC Standard

MOUNT LAUREL, N.J. — The National Air Duct Cleaners Association (NADCA) unveiled 2013 ACR, the NADCA Standard for Assessment, Cleaning, and Restoration of HVAC systems, at its 24th annual conference and exposition, held March 15-18 in New Orleans.

The 2013 ACR Standard has been designed to reflect the most current industry information and best practices of HVAC inspection, cleaning, and maintenance.

“The ACR Standard provides guidance to professionals as they evaluate the cleanliness of system components,” said Matt Mongiello, NADCA president. “The Standard sets an expectation for cleaning and restoring HVAC systems to a specific level of cleanliness.”

The standard provides practical, reliable, and industry-backed information for assessing new and existing HVAC systems; evaluating and verifying the cleanliness of HVAC system components; preventing job-related hazards; and guiding the cleaning and restoration of HVAC systems to a specific level of cleanliness.

The NADCA ACR Standard is available for all industry professionals and defines the minimum performance and procedural requirements for the assessment, cleaning, and restoration of HVAC units. The standard is based on reliable principles, practical experience, and review of applicable industry lecture and information. It focuses on preventing job-related hazards, such as exposure to workers and occupants, as well as cross contamination of the indoor environment.

“It’s important to be sure that the individual or company inspecting your HVAC system is trained and qualified for the job,” Mongiello said. “NADCA-certified professionals are equipped with the knowledge and experience to inspect the air handling system and determine the specific needs for cleaning and restoring the unit, when necessary.”

The 2013 ACR Standard recommends that inspections of air handling systems be performed before and after HVAC cleaning and restoration projects. Doing so helps the contractor determine the current state of the system, the scope of work that needs to be performed, and the tools and equipment needed for the task.
