The 2013 Assessment, Cleaning and Restoration standard has been designed to reflect the most current industry information and best practices of HVAC inspection, cleaning and maintenance, officials said.

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

The standard provides information on judging new and existing HVAC systems, evaluating and verifying the cleanliness of components, preventing job-related hazards, and guiding the cleaning and restoration of HVAC systems.

 “It’s important to be sure that the individual or company inspecting your HVAC system is trained and qualified for the job,” added Mongiello. “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 standard recommends that inspections of air-handling systems be performed before and after HVAC cleaning and restoration projects. The association said that this helps the contractor determine the current state of the system, the scope of work to be performed, and the tools and equipment necessary.
