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 age 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 keep an eye on.Look for these clues: 1. When your vents are totally opened, do any have weaker 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 pet fur?5. Have pests or rodents made a home in your ductwork?6.
