MT. LAUREL, N.J. — The National Air Duct Cleaners Association (NADCA) — also known as the HVAC Inspection, Cleaning, and Restoration Association — announced that its Fall Technical Conference will take place September 16-18 at the Hilton Charlotte University Place in Charlotte, North Carolina.

NADCA’s Fall Technical Conference features hands-on training in every aspect of HVAC system cleaning. Plus, technicians seeking Air Systems Cleaning Specialist (ASCS) or Certified Ventilation Inspector (CVI) certifications will have the opportunity to participate in the pre-conference training course on Thursday, September 16, and exams for both certifications will be offered on Saturday, September 18.

The event will offer an educational program, with industry expert-led sessions featuring topics like tackling exposed and exterior ductwork, upselling to grow sales, reading blueprints, commercial estimating, the impact of filtration in HVAC systems, indoor air quality, and more. Technicians also have access to advanced training tracks about cleaning variable air volume (VAV) boxes, fan coils, and the hidden hazards of duct cleaning, as well as highly technical tracks with hands-on training stations for real-world technical experience.

The conference also provides attendees with the opportunity to gain continuing education credits necessary for certification renewals.

“We’re so excited to return to an in-person format for our Fall Technical Conference,” said Jodi Araujo, CEM, NADCA's CEO. “Like so many other organizations, the unknowns and safety concerns of the COVID-19 pandemic forced us to move to a virtual format for our 2020 event. We really had no sense for the appetite of our members to attend a virtual conference, but clearly the desire was there, as we saw almost 200 attendees at the event and the post-meeting networking happy hour.

“Despite a highly successful virtual event in 2020, our Fall Technical Conference is always a not-to-be-missed in-person event for air duct cleaning technicians, providing extremely valuable hands-on training and education, as well as the opportunity to take the coursework and exams for our ASCS and CVI certifications.”

NADCA’s 2021 Fall Technical Conference is scheduled for September 16-18. Due to continuing COVID-19 restrictions, registration is limited, and on-site registration will not be available. To register or learn more about the event, including a detailed program agenda, visit
