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. Contingent on a lot of factors—like your home’s location, how many pets you have, and how regularly your air filter has been swapped out, 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 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 an obstruction inside your cold air return vent? Are your registers carrying out dust? When you look inside with a flashlight, can you see a buildup of debris or pet fur? Have insects or rodents made a home 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 a smaller amount of airflow than others? If you answered “yes” to any of these questions, it’s most likely time to ask Quality Refrigeration Services in Baltimore about air duct cleaning. Prolonging Time Between Air Duct Cleaning There are some things you can do to help keep your ducts cleaner and prolong the period of time between professional cleanings. Mostly importantly, arrange routine HVAC maintenance with the experts at Quality Refrigeration Services. A maintenance check of your furnace each fall and your AC each spring, which should include inspection, and prospective replacement, of your air filter, will help keep your HVAC system running efficiently, and may help keep your ducts clean. You can also talk to the team at Quality Refrigeration Services about installing an air purification system.

Other measures you can take include: Regularly dusting and vacuuming your home. Examining your air filters habitually and changing them when the manufacturer recommends replacing them.

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