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.

Just like any other HVAC system, air ducts require regular maintenance to ensure maximum efficiency. As a general rule of thumb, the National Air Duct Cleaners Association (NADCA) recommends air duct cleaning every 3 to 5 years. With certain methods, that cleaning recommendation can be extended to 6 to 8 years.

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.

With the lessened amount of debris, duct cleaning can also lead to a cleaner home. Additionally, duct cleaning can improve the airflow in your home, which benefits your HVAC system, improves the overall comfort level of your space, and increases energy efficiency.
