Chief Investigative Correspondent Lisa Guerrero and the Inside Edition I-Squad put air duct service people to the test in the fourth installment in a special series of investigations.

Inside Edition rented a house in Montclair, New Jersey, for an entire month, tricking it out with more than a dozen hidden cameras and then calling in the fix-it guys to see what would happen.

For the fourth installment, we enlisted air duct-cleaning experts from the National Air Duct Cleaners Association, Mark Zarzeczny, and Anthony Paterno, who have a combined 50 years of experience, to fully inspect the home’s air ducts.

“Basically, you just need a basic air duct cleaning,” Zarzeczny told Guerrero.
With hidden cameras everywhere, the house is rigged to see every move anyone inside can make. All of the live footage is transmitted to a remote command post on the first floor.

Guerrero made appointments with companies offering great deals on air duct cleaning. Would they provide a good service or charge us for things we didn’t need?

One man worked for a company offering an $88 special. He entered the home, lugged a big vacuum inside and started cleaning.

“He’s not going the full length of the ducts,” Guerrero noticed from the command post as she watched the footage.

“Exactly, he’s working hard, but it’s very substandard work,” Zarzeczny agreed.

For $50 more, he said he’d clean the big ducts in the attic. He brought up the vacuum but Inside Edition’s hidden cameras showed he never cleaned any of them.

“He charged you extra for the main trunk lines,” Zarzeczny told Guerrero.

“Which he didn’t do,” she replied.

Instead of cleaning the ducts, the cameras caught him looking at a provocative picture of a woman on his cellphone.

Guerrero then revealed her true identity to the man.

“I’m Lisa Guerrero with Inside Edition, did you do a thorough job today?” she asked the technician.
