How to Tell if Your Ducts Need to be Cleaned Posted February 9, 2017 On average, air ducts need to be cleaned every three to five years according to the National Air Duct Cleaners Association. Depending on a lot of factors—like your home’s location, how many pets you have, and how often your air filter has been swapped out, to name a handful—you may need to have air duct cleaning more or less frequently. So, how can you know for sure when it’s time to have your ducts cleaned? There are definitely some significant signs when it’s time. Look for these clues: Are your cold air returns coated with dust or pet hair? Is there an obstruction inside your cold air return vent? Are your registers carrying out dust? When you check inside with a flashlight, can you see a collection of debris or pet fur? Have insects or rodents nestled in your ductwork?
