  • There are two major types of duct cleaning equipment

    Duct cleaning companies use two primary cognitive systems for cleaning pipes. Rotating brush system or push-pull vacuum system. Both systems are designed to remove dirt and debris from lines but achieve very different results.

  • Rotary Brush System

    Typical Vacuum Airflow is around 80-500cfm



    Size of debris that can be removed: The size of the nozzle is the limiting factor here. Larger debris can block the vacuum.


    Integrated Coil Cleaning: Not Recommended - and the brush can damage your coil.


    Dampers: Not Recommended - for Systems with Dampers: Brush cannot pass through dampers.


    Wiring in Ductwork:  Not Recommended - house wiring can tangle and wrap around the brush.


    Geothermal ductwork: Not Recommended - Small sensors & fans will get damaged in the ductwork from the brush.


    Not able to handle sharp turns in smaller diameter ductwork: Vacuum hose is usually 3-inch diameter and is prone to getting stuck. There is a 1.25 hose but, limited with a very weak vacuum and will get clogged with a candy wrapper.

  • Negative Air Pressure

    Typical Vacuum Airflow is around 3000cfm + at hook up point.


    Size of debris that can be removed: Larger toys, construction debris, dead rodents, and more can be dislodged and removed from the ductwork.


    Integrated Coil Cleaning: Yes, coils are cleaned with compressed air that is included in our normal cleaning


    Recommended for systems with Dampers: Air Hose is small enough to pass through Dampers.


    Ability to handle sharp turns in smaller diameter ductwork: Air Sweep and brush are less than 1 inch in diameter.
