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 tell if it’s time to have your ducts cleaned? We’ve got some signs that you should watch for.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 listen to the airflow? 3. Is there anything blocking your cold air return vent?4. When you glimpse inside with a flashlight, is there a buildup of debris or fuzz from your pet’s hair?5. Have insects or rodents created a home in your ductwork?6. Are your cold air returns layered with dust or pet hair?7.
