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 length of time you’ve had 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 indications that you should watch for.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 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 fur?5. Have pests or rodents made a home in your ductwork?6. Are your cold air returns layered with dust or pet hair?7.
