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, if you have pets, and how regularly your air filter has been changed, to name a handful—you may adjust your air duct cleaning more or less often. So, how can you know for sure when it’s time to have your ducts cleaned? There are certainly some telltale signs when it’s time. Look for these clues: Are your cold air returns coated with dust or pet hair? Is there a jam within your cold air return vent? Are your registers blowing out dust? When you look inside with a flashlight, can you see an accumulation 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 not as much airflow than others? If you answered “yes” to any of these questions, it’s probably time to ask Cronin-Verheul Heating & A/C Ltd in Waterloo about air duct cleaning.

Replacing poor or impaired air-duct insulation. With a specialized air duct cleaning and some preemptive measures, you can help keep the air in your Waterloo home clean and healthy.
