There is no set frequency for air duct cleaning in residential or commercial buildings, but it is
generally recommended to get them cleaned every 1-3 years, or when there is visible mold
growth, substantial amounts of dust or debris, or any noticeable decrease in air quality. It's also
recommended to have them inspected annually to assess the need for cleaning. Factors such as
occupancy, environmental conditions, and the type of HVAC system can also affect the
frequency of cleaning. It's always a good idea to consult with our professional contractors to
determine the best schedule for your specific needs.
