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 at least once every three to five years on average. Your home’s location, your pets and the lifetime 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 signals that you should keep an eye on.Look for these clues: 1. When your vents are fully opened, do any have weaker airflow than others?2. Can you hear a sound other than your blower motor when you listen to the airflow? 3. Is there anything blocking your cold air return vent?4. When you glimpse inside with a flashlight, can you see a buildup of debris or pet hair?5. Have insects or rodents fashioned a home in your ductwork?6. Are your cold air returns coated with dust or pet hair?7.
