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. Dependent on a lot of factors—like your home’s location, whether or not you have pets, and how often your air filter has been changed, to name some—you may require air duct cleaning more or less frequently. So, how can you find out for sure when it’s time to have your ducts cleaned? There are certainly some revealing signs when it’s time. Look for these clues: Are your cold air returns caked with dust or pet hair? Is there a blockage within your cold air return vent? Are your registers blowing out dust? When you gaze inside with a flashlight, can you see a buildup of debris or pet fur? Have insects or rodents found shelter in your ductwork? Can you hear noise other than your blower motor when you listen to the airflow? When your vents are fully opened, do any have less airflow than others? If you answered “yes” to any of these questions, it’s more than likely time to ask Smyth Air Conditioning Inc in Lake Worth about air duct cleaning.
