How to Tell if Your Ducts Need to be Cleaned02/09/2017Generally, 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, how many pets you have, and how regularly your air filter has been changed, to name some—you may require air duct cleaning more or less often. So, how can you tell for sure when it’s time to have your ducts cleaned? There are definitely 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 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 nestled 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 probably time to ask Bishop Heating & Air Conditioning in Bishop about air duct cleaning.
