How to Tell if Your Ducts Need to be Cleaned Posted February 9, 2017 Generally, air ducts need to be cleaned every three to five years according to the National Air Duct Cleaners Association. Contingent on a lot of factors—like your home’s location, if you have pets, and how frequently your air filter has been replaced, to name a few—you may need to have air duct cleaning more or less regularly. So, how can you know 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 jam within your cold air return vent? Are your registers blowing out dust? When you gaze inside with a flashlight, can you see a collection of debris or pet fur? Have insects or rodents found shelter in your ductwork? Can you hear clatter other than your blower motor when you listen to the airflow? When your vents are fully opened, do any have a smaller amount of airflow than others? If you answered “yes” to any of these questions, it’s probably time to ask Custom Air Systems Inc in Port St. Lucie about air duct cleaning.
