CHALLENGE:
As HVAC systems have evolved over the past decades, so have methods for maintaining them—including properly cleaning air ducts. 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.
SOLUTION:
NADCA: The HVAC Inspection, Cleaning and Restoration Association developed a standard that makes clear the positive impact of professional air duct cleaning. ACR, The NADCA Standard for Assessment, Cleaning & Restoration of HVAC Systems, is an internationally recognized benchmark for HVAC system cleaning and maintenance. The standard guides proper cleaning to restore HVAC systems to peak efficiency while improving indoor air quality. Cleaning to ACR involves meticulous procedures carried out by trained technicians, ensuring thorough removal of contaminants and restoring airflow to optimal levels.
IMPACT:
A recent peer-reviewed study published in Energy and Buildings demonstrates that 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. These findings solidify the importance of maintaining HVAC systems to align with corporate and individual goals for environmental stewardship while also reducing operating costs, enabling businesses to reinvest in other areas. For service providers, compliance with ACR offers a competitive advantage by demonstrating adherence to rigorous industry benchmarks, building public trust, and attracting more clients. Additionally, cleaning to ACR improves system efficiency and enhances indoor air quality by removing harmful contaminants such as dust, mold, and debris—fostering healthier living and working environments, reducing the risk of respiratory illnesses, and improving overall quality of life.
