How to Tell if Your Ducts Need to be Cleaned Posted February 9, 2017 According to the National Air Duct Cleaners Association, air ducts need to be cleaned at least once every three to five years on average. Your home’s location, your pets and the length of time you’ve had 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 signals that you should keep in mind.Look for these clues: 1. When your vents are totally opened, do any have weaker airflow than others?2. Can you hear a sound other than your blower motor when you focus on the airflow? 3. Is there an obstruction in your cold air return vent?4. When you glimpse inside with a flashlight, do you see a buildup of debris or pet hair?5. Have pests or rodents fashioned a home in your ductwork?6. Are your cold air returns layered with dust or pet hair?7.
