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. Your home’s location, your pets and the age of your air filters—along with many other factors—can influence the amount of time between cleanings. How can you see if it’s time to have your ducts cleaned? We’ve got some indications that you should keep in mind.Look for these clues: 1.
