The American National Standards Institute (ANSI) has officially recognized ACR, The NADCA Standard for Assessment, Cleaning & Restoration of HVAC Systems, as a benchmark for HVAC system maintenance and cleaning. This standard, developed by NADCA: The HVAC Inspection, Cleaning and Restoration Association, provides comprehensive guidelines for professional air duct cleaning and system restoration.
According to ANSI’s assessment, the standard addresses a significant industry challenge where “a lack of updated guidance on the methodology and benefits of proper air duct cleaning created confusion among consumers and limited industry growth, while leaving potential energy efficiency gains untapped.”
The impact of implementing ACR protocols has been substantial. A peer-reviewed study published in Energy and Buildings demonstrates that proper HVAC system cleaning can lead to significant energy savings. “Adherence to ACR protocols can reduce energy consumption by 30% or more, with studies showing up to 60% reductions in fan energy and a 46% increase in airflow,” the ANSI report states.
NADCA emphasizes that this recognition reinforces the standard’s credibility.
“ANSI is the premier non-profit organization that accredits standards-developing bodies like NADCA to ensure that their processes are fair, transparent, and balanced,” said Jeanne Cekala, NADCA Standards and Specifications Marketing Manager.
The standard’s implementation extends beyond energy efficiency. For facility managers and building owners, ACR compliance offers multiple benefits, including improved indoor air quality through the removal of contaminants such as dust, mold, and debris.
This enhancement contributes to “healthier living and working environments, reducing the risk of respiratory illnesses, and improving overall quality of life,” according to ANSI’s assessment.
For service providers, the standard serves as a competitive differentiator, demonstrating adherence to rigorous industry benchmarks. The protocol involves “meticulous procedures carried out by trained technicians, ensuring thorough removal of contaminants and restoring airflow to optimal levels.”
This recognition comes at a time when building efficiency and indoor air quality are increasingly prioritized in facility management. The standard provides a framework for both environmental stewardship and operational cost reduction, allowing businesses to reinvest savings in other areas while maintaining healthy indoor environments.
