How to Tell if Your Ducts Need to be Cleaned02/09/2017On average, 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 often your air filter has been replaced, to name a few—you may adjust your air duct cleaning more or less often. 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 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 a collection of debris or pet fur? Have insects or rodents found shelter 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 a smaller amount of airflow than others? If you answered “yes” to any of these questions, it’s more than likely time to ask O'Brien Heating & Air Conditioning in the Main Line about air duct cleaning.
