Industry-Leading Duct Cleaning Procedure

Our technicians connect the truck-powered vacuum to your home or office’s air handler with a 10″ hose. Next, a high-velocity air sweeper is inserted into the ductwork, which is controlled by a hose connected to the truck’s air compressor that supplies up to 200 pounds of air pressure.

Duct Doctor’s patented vacuum truck is the industry’s most powerful. The vacuum and cleaning apparatus used together ensure that all contaminants are removed from the ductwork and stored outside in the truck’s debris collector for safe disposal. We cater our service to the unique needs of each location, and stay until the job is done right.

We professionally service residential and commercial properties.

How It’s Done

  1. 10,000 cubic feet per minute of suction is delivered by our unique vacuum truck to an access port created in your duct system.

  2. 150-200 psi of air is then applied to inside of duct surfaces through various tools attached to hollow poles. This separates the debris from the walls of your ductwork.

  3. The combination of high pressure agitation and heavy suction immediately conducts the debris out of your home or office, directly into our truck, where it is hauled away and safely disposed of.

You Can Breathe Easy

Our process is very safe as we eliminate the need for handheld devices that exhaust into the air envelope of your home or office, reintroducing those irritants back into the air you breathe, even through filters. “Shop Vacs” should NOT be used to clean ducts except for outer surfaces for this reason, and we don’t clean ducts with them!

Our system conducts the debris directly to our truck outside, the air is filtered, then released out of the top of the truck. The air exhausted from the truck is cleaner than the air inside a home and is cleaner than the outdoor air as well! This provides for safety of neighbors and children outside at play in addition to protecting your indoor air quality.
