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.

These calls originate in other countries who are selling cheap duct cleaning services to get into your home for the upsell. They will try to validate themselves by mentioning the name of a local duct cleaning company, sometimes even referring to the real company's website.

While HVAC maintenance focuses on comprehensive system upkeep and performance, duct cleaning specifically targets the cleanliness of the ductwork. By reducing airflow restrictions and improving indoor air quality, both services contribute to the longevity and efficiency of your HVAC system.

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.
