After a long review period, the new NADCA ACR 2013 has been published and is being integrated into DUCTZ of North Phoenix and Deer Valley cleaning protocols. While many of the standards have remained the same, there are some critical sections that have been changed that will immediately impact how an HVAC air system must be cleaned. Want to make sure your current (or upcoming…) projects are in compliance? Visit the NADCA website at http://www.nadca.com and call us at 623-466-8625 for more info. DUCTZ Project managers are standing by to explain the changes and help you with your projects!
