Abstract: The disclosed embodiments include systems and methods to clean ducts. In one embodiment, the method includes detecting airflow into an exhaust duct. The method also includes dosing, in response to detecting airflow into the exhaust duct, an amount of a treatment product with a fluid to produce a treatment fluid. The method also includes pumping the treatment fluid into a pipe deposited along the exhaust duct. The method also includes spraying the treatment fluid through a nozzle coupled to a section of the pipe to clean buildup formed along an area of the exhaust duct proximate to the nozzle.
