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. Depending on a lot of factors—like your home’s location, whether or not you have pets, and how regularly your air filter has been replaced, to name a handful—you may require 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 absolutely some revealing signs when it’s time. Look for these clues: Are your cold air returns caked with dust or pet hair? Is there an obstruction inside your cold air return vent? Are your registers carrying out dust? When you look inside with a flashlight, can you see an accumulation of debris or pet fur? Have insects or rodents made a home in your ductwork? Can you hear sound 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 Hammack Service Company in Richardson about air duct cleaning.
