How to Tell if Your Ducts Need to be Cleaned Posted February 9, 2017 According to the National Air Duct Cleaners Association, air ducts must be cleaned 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 this timeline. How can you tell if it’s time to have your ducts cleaned? We’ve got some signals that you should keep an eye on.Look for these clues: 1. When your vents are totally opened, do any have less adequate airflow than others?2. Can you hear something 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, can you see a buildup of debris or fuzz from your pet’s hair?5. Have insects or rodents created a home in your ductwork?6.
