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, how many pets you have, and how regularly your air filter has been changed, to name a few—you may need to have air duct cleaning more or less frequently. So, how can you tell for sure when it’s time to have your ducts cleaned? There are definitely some significant signs when it’s time. Look for these clues: Are your cold air returns coated with dust or pet hair? Is there a blockage within your cold air return vent? Are your registers blowing out dust? When you check 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 noise 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 more than likely time to ask Oak Grove Heating & Air Conditioning in Hattiesburg about air duct cleaning.
