How Often Should Air Ducts Be Cleaned?

Most homeowners should schedule professional air duct cleaning every 2 to 3 years. However, several factors can affect this timeline.

Factors That Affect Cleaning Frequency

Pet owners may need more frequent cleaning due to dander and hair accumulation. Homes with allergy sufferers, recent renovations, or high dust levels may also benefit from shorter intervals.

Ontario Climate Considerations

Canadian winters mean your heating system runs for months, pushing more air through your ducts. Seasonal transitions can also introduce more outdoor particles into your home.

When to Schedule Sooner

If you notice persistent dust on surfaces shortly after cleaning, reduced airflow from vents, or musty odors when your system runs, these are signs your ducts may need attention.
