We use two different air duct cleaning systems: the Nikro Negative Air system, and the Rotobrush system. Both are effective in removing duct contaminants, but the processes vary. Keep reading to learn about both pieces of equipment and their associated air duct cleaning process.

Rotobrush Duct Cleaning Process

  • First, we use a video inspection system to evaluate your home’s duct work. We look for dirt, debris, animal droppings, mold and moisture.
  • Then, we remove all your register covers and clean them thoroughly.
  • Next, our technicians insert a hose and rotating brush head into your duct work and begin cleaning the ducts.
  • After cleaning the ducts, we clean the supply and return air plenums and the filter housing.
  • Once the whole system is scrubbed clean, we fog the ducts with an EPA-approved antimicrobial mist, which also leaves a pleasant scent behind.

Nikro Negative Air Machine Process

This is a newer system which uses compressed air, rather than a brush, to dislodge contaminants and debris. Please view the video playlist for an explanation of the process from start to finish.


Regardless of what equipment is used, it is essential that certain methods are used during a duct cleaning. These methods ensure that your ducts are left completely clean, and no contaminants are released into your home in the process.

Breaking Contaminants Loose: Properly cleaning air ducts requires removing the sources of contamination. This begins with the use of one or more agitating devices designed to loosen contaminants from the surfaces of the duct work. We use brushes, air whips and compressed air.  Hand brushing or contact vacuuming can also loosen contaminants and debris.

Collection of Contaminants: During your duct cleaning we put your duct work under negative pressure (vacuum) to prevent the spread of contaminants (dust, hair, etc.). Continuous negative pressure allows very fine particles to be removed from the system as they become air borne, ensuring that these particles are not released in to the living space when the system is turned back on after the cleaning.

System Access: Since each house or building is unique in its own way, each HVAC system is set up a little bit differently. Where possible, our technician will access your air ducts through all of your supply registers, cold air returns, and will also cut access holes in the duct work in order to reach inside with various cleaning tools. Creating these service openings and patching the holes requires craftsmanship and professional training.
