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.

How can you know 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 noise other than your blower motor when you focus on the airflow? 3.
