Duct cleaning has never been shown to actually prevent health problems. Neither do studies conclusively demonstrate that particle (e.g., dust) levels in homes increase because of dirty air ducts. This is because much of the dirt in air ducts adheres to duct surfaces and does not necessarily enter the living space.

It's a Mess: Air duct cleaning can be a messy process. The technician will need to access your ductwork, which means they'll likely need to drill holes in your walls or ceilings. This can create dust and debris that will need to be cleaned up after the job is done.

At On Time Home Services, we recommend scheduling regular air duct cleaning services from a professional HVAC technician to keep your system in the best possible shape, but in between professional maintenance visits you can clean them yourself.

Even if your ducts are very dirty, cleaning them likely won't lower dust levels throughout your home. Maintaining clean air ducts in your home probably seems like something you should do.
