The Chimney Safety Institute of America has taken one of the boldest steps in the history of the Certified Dryer Exhaust Technician (or C-DET) credential by partnering with the National Air Duct Cleaners Association. The CSIA board on May 23, 2014 approved a first-ever Memorandum of Understanding (MOU) between both associations. 

It gives homeowners another reason to hire a CSIA certified specialist.

NADCA has more than 1,000 member companies with over 1,700 Air Systems Cleaning Specialists, a certification specifically for HVAC system Inspection, Cleaning and Restoration that includes any ventilation/exhaust ducts, except kitchen exhaust. 

NADCA’s member companies have an estimated 5,000 technicians, many of whom include Dryer Exhaust (DE) cleaning with their duct cleaning services. 

“Presently we do not have a separate certification for Dryer Exhaust and do not wish to develop one. The CSIA C-DET certification is an excellent fit for our NADCA members,” said Jodi Araujo, Executive Director, NADCA, of Mt. Laurel, New Jersey. “We are looking forward to a fantastic and mutually beneficial relationship.” 



CSIA also will make available to NADCA members their online and in-person courses at a discounted price, including a C-DET review at NADCA’s Sept. 18 Fall Technical Conference in Atlanta, Georgia. (Sign up using our Chimney Safety Institute of America event calendar.)

NADCA will promote these courses as part of its education program.

“We have more than 1,400 professionals who hold the CCS, or Certified Chimney Sweep, credential. We think the number of people who hold the C-DET certification could be just as big, if not larger,” said Mark A. Stoner, CSIA president. “We are in the process of preparing to launch a special website,, devoted just to C-DET pros. It’s an affordable certification and, based on the number of unwanted fires annually because of lint-clogged ducts, it’s critically important that homeowners get the information that will prevent an unwanted fire.”
