How to Tell if Your Ducts Need to be Cleaned Posted February 9, 2017 Typically, air ducts need to be cleaned every three to five years according to the National Air Duct Cleaners Association.

So, how can you find out for sure when it’s time to have your ducts cleaned? There are certainly some telltale signs when it’s time.

When you gaze inside with a flashlight, can you see a collection of debris or pet fur? Have insects or rodents made a home in your ductwork?
