3. New Homeowners: If you have recently purchased a new home, it is advisable to schedule an air duct cleaning. This ensures that any debris or contaminants from the construction process are eliminated.

4. After Renovations: Schedule an air duct cleaning after completing home renovations or remodeling projects to remove dust and debris that may have entered the ductwork during construction.
