When Mark Zarzeczny first became involved in air duct cleaning 25 year ago, the many in the industry were inexperienced in proper techniques — and that includes him, he adds.

“We did not perform projects I feel as best we could when we began,” says Zarzeczny, who now sits on the board of directors for the National Air Duct Cleaners Association as well as several committees. “That’s one of the reasons that  we became members of the National Air Duct Cleaners Association so we could lean the proper ways of doing things be learning from some of the forefathers of our industry.”

Zarzeczny, who owns Schoen Air Duct Cleaning of New Jersey, says he still likes to learn from the members of NADCA with even more experience than him.

“A lot of them are still around and a lot of them are very, very active in a lot of the committees that we have,” he said.

The chance to learn from industry peers is one of the reasons that Zarzeczny says he really excited about this year’s annual convention. NADCA will bring its 28th annual conference to Walt Disney World’s Contemporary Resort in Lake Buena Vista, Florida next week. Monday through Wednesday, the hotel perhaps best known for a monorail running through its lobby connecting it to the Magic Kingdom will be full of professionals involved in this growing industry.

Among the scheduled sessions are discussions on service agreements, insurance, dealing with mold, what legal marijuana may mean for the indoor air quality industry, and online HVAC sales and marketing tips.  

They’re expecting a record attendance.

“We’re really excited about having it in Disney this year,” Zarzeczny says. “We have an incredible program set up.”

Following a golf outing and daylong certification classes Monday, the convention will start at 5 p.m. with a trade show and welcome reception.

The next day will include more certification testing and a keynote address from Jeff Williford of the Disney Institute. He will speak at 10 am. Tuesday about the Walt Disney Co.’s approach to customer service.

Zarzeczny says he’s especially thrilled to have an expert in Disney company culture at this year’s event.

“To learn anything from one of the most recognized brands in the world and to be able to take that back with you to your business is just an incredible takeaway,” he says.

And there are lessons from the entertainment giant that can be applied to air duct cleaning, he added.

Wednesday will include talks on duct pressure testing and leakage and discussions on duct sealing and building codes. Panelists are scheduled to include Tim Eorgan from Hardcast-Carlisle, Neal Walsh of Aeroseal and Scott Witherow of Design Polymerics.

NADCA overall — and the convention in particular — helps to increase the professional standing of the air-duct cleaning industry and the companies who belong to the association, Zarzeczny says.

“We must be doing something right because the industry is growing,” he adds. “I know that our membership is growing. We had a 97 percent renewal this year and I think it was 98 percent last year.”
