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 at least once every 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 how long your ducts can go without cleaning. 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. When your vents are fully opened, do any have less airflow than others?2. Can you hear noise other than your blower motor when you pay attention to the airflow? 3. Is there anything blocking your cold air return vent?4. When you look inside with a flashlight, do you see a buildup of debris or fuzz from your pet’s hair?5.
