How to Tell if Your Ducts Need to be Cleaned02/09/2017Typically, air ducts need to be cleaned every three to five years according to the National Air Duct Cleaners Association. Depending on a lot of factors—like your home’s location, how many pets you have, and how regularly your air filter has been swapped out, to name some—you may need to have air duct cleaning more or less regularly. 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. Look for these clues: Are your cold air returns covered with dust or pet hair? Is there an obstruction within your cold air return vent? Are your registers wafting out dust? 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?
