Our air duct and duct cleaningtechnicians are trained and certified by Carrier Aeroseal to expertly inspect, analyze and fix leaky air ducts with Carrier Aeroseal’s unique diagnostic inspection and duct sealing injection system. 

Our system was developed in a University of California Berkeley laboratory. It enables us to perform accurate computer-assisted diagnostic inspection tests, generate reports and seal leaks internally from inside a ductwork system. This amazing heat & air-assisted injection system negates the necessity of opening walls, ceilings or floors for air duct access.

Our Sealing Process

Air duct repairs are made from inside a ductwork system with a Carrier Aeroseal heat and air-assisted injection system. This method completely eliminates the very expensive need to open walls, ceilings, floors & other inaccessible areas to make most repairs.

To start the duct sealing process, all room, ceiling and  floor registers are blocked off.

A small access hole is cut into the supply or return-air plenum and a temporary collar attached. The furnace or air conditioning indoor coil and fan are temporarily blocked to avoid the entrance of sealing particles into their equipment. 

Once the system is properly sealed,  the patented injection machine is connected to the air duct system with a flexible plastic tube.

The exclusive Carrier-Aeroseal duct sealing system injects adhesive particles into the air duct system. The particles travel through the air duct system seeking holes and cracks that are located throughout the ductwork. The adhesive duct sealing particles attach directly onto the edges of any hole and crack effectively sealing it without coating the inside of the ductwork.

YOUR AFTER SEALING REPORT










A sealing certificate and a tightness certification are generated by our computer. The certificate shows duct leakage amounts before and after sealing, as well as a graph of the sealing process and overall heating or cooling capacity improvement. The tightness certification, affixed to your duct system, shows the tightness of the duct system after completion of the sealing process.
