Professional duct cleaning companies advertise in local service directories and in the Yellow Pages, and the National Air Duct Cleaners Association also provides listings for professional duct cleaners online. With a wide variety of options, consumers should research their options before making a decision.
Consumers should check out at least three different local companies and ask each company about their duct cleaning process, safety precautions and employees' experience before choosing one. Consumers should be wary of companies that make strong claims about the health benefits of duct cleaning, as these claims are unsubstantiated according to the U.S. Environmental Protection Agency. In addition to talking directly with the companies, checking references of the potential companies or researching the company with the Better Business Bureau can help consumers to choose the best service provider.
