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 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 the amount of time between cleanings. How can you see if it’s time to have your ducts cleaned? We’ve got some indications that you should keep in mind.Look for these clues: 1. When your vents are fully opened, do any have less adequate airflow than others?2. Can you hear a sound other than your blower motor when you pay attention to the airflow? 3. Is there an obstruction in your cold air return vent?4. When you peek inside with a flashlight, do you see a buildup of debris or pet hair?5. Have bugs or rodents fashioned a home in your ductwork?6.
