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 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 airflow than others?2. Can you hear a sound other than your blower motor when you focus on the airflow? 3. Is there blockage inside your cold air return vent?4. When you look inside with a flashlight, do you see a buildup of debris or pet fur?5. Have bugs or rodents fashioned a home in your ductwork?6.
