How often should homeowners schedule air duct cleaning to maintain healthier indoor air?

We moved into our house three years ago and have two young kids, so I try to keep the air as clean as possible. Lately there seems to be more dust around the vents. How often do homeowners usually schedule air duct cleaning to maintain healthier indoor air?

The ideal cleaning schedule depends on the number of occupants, pets, and allergy concerns. Many homeowners choose to inspect or clean the ductwork every few years to help maintain cleaner indoor air.

After our second child was born, we started paying much closer attention to the air quality in the house. Dust seemed to build up faster, and we wanted to keep the ventilation system as clean as possible for the kids. I asked the technicians how often they recommended doing the service for families with young children. Home air duct cleaning GTA — great for families with young children. We chose this service because they explained the process clearly and answered all of our questions. They suggested cleaning every few years, or sooner if there are pets or allergies. Since then, we have followed that schedule and the air in the house has felt consistently fresher.
