How to Tell if Your Ducts Need to be Cleaned Posted February 9, 2017 According to the National Air Duct Cleaners Association, air ducts need to be cleaned every three to five years on average.

How can you see if it’s time to have your ducts cleaned? We’ve got some signs that you should watch for.Look for these clues: 1.
