How often should you have your air ducts cleaned?
Most homes do not need air duct cleaning every year, but many homeowners consider professional air duct cleaning every 3 to 5 years depending on the home, HVAC system, and indoor air concerns. The right timing depends on how the house is used, whether pets live in the home, whether allergies are a concern, and whether there has been recent remodeling or visible buildup around vents.
- Typical homes: consider inspection or cleaning every 3 to 5 years.
- Homes with pets or allergy concerns: service may be needed more often, especially if dust and dander collect quickly.
- After renovations: schedule an inspection if drywall dust, sawdust, or construction debris may have entered the duct system.
- Musty odors or visible debris: do not wait for a schedule; these are signs the system may need attention sooner.
- Unknown history: if you recently moved in and do not know when the ducts were last cleaned, an inspection can help.
Changing your home’s air filters regularly can help, but filters do not remove all pollutants that may collect within the system. For a complete overview, visit our Air Duct and Dryer Vent Cleaning Guide for Homeowners.
Being in your home this winter with your heat on could affect indoor air quality, especially if your air duct system has not been cleaned in the past 5-10 years. Just as dust and dirt collect on your floor, pollutants such as pollen, dust, pet dander, mold spores, bacteria, and dust mites can collect on the surface of your air ducts and recirculate through your house.
