How to Tell if Your Ducts Need to be Cleaned Posted February 9, 2017 According to the National Air Duct Cleaners Association, air ducts should be cleaned about three to five years on average. Your home’s location, your pets and the lifetime of your air filters—along with many other factors—can influence this timeline. How can you tell if it’s time to have your ducts cleaned? We’ve got some signs that you should keep an eye on.Look for these clues: 1. When your vents are completely opened, do any have less airflow than others?2. Can you hear a sound other than your blower motor when you focus on the airflow? 3. Is there anything blocking your cold air return vent?4. When you glimpse inside with a flashlight, do you see a buildup of debris or pet fur?5. Have pests or rodents created a home in your ductwork?6.
