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 length of time you’ve had your air filters—along with many other factors—can influence this timeline. How can you see if it’s time to have your ducts cleaned? We’ve got some signals that you should keep in mind.Look for these clues: 1. When your vents are totally opened, do any have less adequate airflow than others?2. Can you hear noise other than your blower motor when you listen to the airflow? 3. Is there blockage inside 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 pests or rodents created a home in your ductwork?6.
