Air Duct Sealing

"In a typical house about 20 to 30 percent of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts."

We "ARE"

...partnered with the leaders leading the industry in sealing air duct systems.

A Few Things To Know

The ductwork that is separated at the joints, plenums with broken or rusted‐out seams, improperly sealed access openings or doors, and other sources of air leakage can be a significant source of energy waste.


Plugging your registers with foam forces the air in your ductwork to escape through leaks. By forcing air to escape through leaks we able to pretest your duct system and begin the duct sealing process. 



A small access hole is cut into the supply or return and a temporary collar is attached. The air conditioning indoor coil, fan, and furnace are temporarily blocked with a foam plug to prevent sealant particles from entering this part of your system.



Once the system is properly prepped the Aeroseal machine is connected to the ductwork using lay-flat tubing. The Air Duct Diagnostic pretest will detect the exact amount of duct leakage in the duct system - the typical duct leakage detected in a home is between 30-40%.



Small aeroseal particles are injected and kept suspended in the airflow by continuous air movement. The aeroseal particles begin collecting on the edges of holes and cracks in your ductwork and seal your leaky ductwork from the inside. 



A computer-generated analysis summarizes your home's duct leakage reduction providing you with verification of the success of the Aeroseal application. Once the process is complete your certified A&R Environmental / Aeroseal technician will provide you with a printed certificate summarizing results.
