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 at least once every 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 the amount of time between cleanings. 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 completely opened, do any have weaker airflow than others?2. Can you hear noise other than your blower motor when you listen to the airflow? 3. Is there anything blocking your cold air return vent?4. When you peek inside with a flashlight, do you see a buildup of debris or fuzz from your pet’s hair?5.
