Importance Of Duct Cleaning Standards And Certification

July 28, 2023

As a contractor, having the right air duct cleaning tools is essential to complete any duct cleaning task efficiently and effectively. However, it is even more important as a contractor to have the right certification, as it can really enhance your reputation and business. Apart from that, it is equally essential to have appropriate standards for air duct cleaning tools. In this blog, 3 such standards and certifications and their respective governing bodies will be explored.


Duct Cleaning Certification Bodies


The National Air Duct Cleaners Association (NADCA)


Founded in the United States, NADCA is a leading body when it comes to providing certification and upkeeping standards for HVAC systems, tools, and contractors who undertake the cleaning process. It also represents the best interests of the air duct cleaning companies. There are 2 more specifications that come under NADCA, Air Systems Cleaning Specialist (ASCS) and Certified Ventilation Inspector (CVI). 


Air Systems Cleaning Specialist (ASCS)


Having an ASCS certification means you know how to properly diagnose problems in a HVAC system and you also know the right tools required to solve the problem. This gold standard of air duct cleaning ensures you and your employees possess the required knowledge to handle most HVAC systems.


Certified Ventilation Inspector (CVI)


This is a step further to the standard ASCS certification. Being a Certified Ventilation Inspector (CVI) is the highest certification offered by NADCA. This is offered to those who are experts in commercial HVAC systems. This improves a cleaner’s prospects in the industry and guarantees respect and recognition.
