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 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 know 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 pay attention to the airflow? 3.
