When it comes to duct cleaning, there are numerous options out there. However, not all duct cleaners are created equal. Some consumers will go with the "cheapest price". Not all cleaners clean the same way and if someone is offering a much cheaper price there is a reason why. A great way to avoid getting scammed is to check that a company is licensed and carries proper liability insurance. You can also look for certification by the National Air Duct Cleaners’ Association (NADCA).www.nadca.com. At AVL Duct Scrubbers, we are proud to be NADCA certified.
