Our Air Duct Cleaning Process
Our air duct cleaning process is called negative air cleaning or the push-pull system. We use brushes and compressed air to push the dust and debris toward a highly efficient filtration system that will trap even the smallest dust particles.
The equipment we use to perform this process is a large HEPA filtered duct cleaning machine connected to your air duct system next to your furnace. This machine puts the entire system under negative air pressure allowing us to use rotating brushes and compressed air to clean and push all the dust and debris from each vent to the HEPA filtered vacuum system. This allows us to clean each supply, each return air vent, and the main line of the home.
Because we have the whole system closed up except the vent we are cleaning there is very little chance of dust getting out of the duct system while cleaning. Our vacuum system is running the whole time which will be cleaning your air while we are there.
To effectively clean your entire air duct system we will need to make some access openings. These will all be sealed after cleaning with a metal plate or plastic caps. This is all standard and is required to completely clean your system. The pictures to the right will give you an idea of what it looks like.
The large opening is for our negative air machine access, this is needed because of the amount of air flow needed to properly clean your air ducts system. The small holes are for us to gain access with our brushes and air compressor air hose. We use a brush and a lot of compressed air from the smaller openings to push all the dust and debris toward the larger opening where our negative air machine is pulling it toward. This keeps the dust contained in the ventilation system while we are cleaning and allows a complete cleaning of your air duct system.
