How to Tell if Your Ducts Need to be Cleaned Posted February 9, 2017 On average, 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 replaced, to name some—you may need to have air duct cleaning more or less regularly. So, how can you tell 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 covered with dust or pet hair? Is there a jam inside 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 noise 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 most likely time to ask Keystone Heating & Air Conditioning Co., Inc in Racine about air duct cleaning. Prolonging Time Between Air Duct Cleaning There are some things you can do to help keep your ducts cleaner and lengthen the period of time between specialized cleanings. First and foremost, arrange routine HVAC maintenance with the experts at Keystone Heating & Air Conditioning Co., Inc. A tune-up of your furnace each fall and your AC each spring, which should include inspection, and potential replacement, of your air filter, will help keep your HVAC system running well, and will help keep your ducts clean.

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