Aeroseal Duct Sealing—The Process
Aeroseal duct sealing is a patented, breakthrough technology that tackles leaks from the inside out. Aeroseal software allows your Bruening Heating professional to accurately measure the duct leakage in your IL home or business. The Aeroseal process puts escaping air under pressure and causes polymer particles to stick first to the edges of a leak, then to each other, until the leak is closed.
The technology was developed within the Indoor Environment Program at Lawrence Berkeley National Laboratory, where indoor air quality (IAQ) scientists tested it. The research was funded by the US Environmental Protection Agency (EPA), US Department of Energy (DOE), Electric Power Research Institute (EPRI), and the California Institute of Energy and Environment (CIEE).
Air Duct Sealing Process
The patented Aeroseal sealing process is the most effective, affordable, and viable method of sealing the central heating, ventilation, and air conditioning (HVAC) ductwork in residential homes. The Aeroseal process won the “Best of What’s New” award from Popular Science magazine and the “Energy 100” award from the DOE.
Sealing the air duct system in your Quincy home typically takes only a few hours. You will immediately receive energy savings and a noticeable improvement in home comfort. The Aeroseal duct sealing system effectively seals your home’s ductwork from the inside by using a UL (Underwriters Laboratories) tested and approved sealing material. It’s clean, safe, and guaranteed for 10 years in a residential application.
Diagnosis and Inspection
In an Aeroseal air duct diagnostic, your certified Bruening Heating Aeroseal expert inspects and evaluates your central air duct system and recommends ways to maximize your savings, improve your home comfort and efficiency, and solve airflow/ventilation problems.
Major considerations during inspections are construction practices; type of ductwork; age of your home; hot, cold or stuffy rooms; indoor air quality problems; and high energy bills. Our trained and certified technicians use computer-based tools and reports to gather information about duct leakage and register airflows.
Seal and Verify
To start the Aeroseal duct sealing process, all wall, ceiling, and floor registers are replaced with foam plugs. A small access hole is cut into the supply or return air plenum and a temporary collar is attached. The air conditioning indoor coil, fan, and furnace are temporarily blocked with a foam plug to avoid the entrance of any sealing particles into this equipment.
Once the system is properly sealed, the patented injection machine is connected to the air duct system using a flexible plastic tube. The exclusive Aeroseal duct sealing system injects adhesive particles into the ductwork.
These particles travel through the air duct system seeking holes and cracks 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.
Measuring the Duct Seal
Once the Aeroseal air duct sealing is complete, our team will again measure the duct system leakage. A sealing certificate and a tightness certification are generated by the computer.
The sealing certificate shows duct leakage amounts before and after sealing as well as a graph of the sealing process, plus 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.
Duct Sealing Certification
When the sealing process is completed, our team verifies the results and provides you with them.
Duct Sealing Warranty
The air sealing system results are guaranteed for 10 years for residential homes.
This technology internally seals duct leaks in air distribution ducts by injecting a fog of aerosolized sealant particles into a pressurized duct system. The key to the technology is to keep the particles suspended within the air stream without depositing them on the duct surfaces until they reach the leaks. This is where they leave the air stream, deposit at the leak edges, and seal the leaks.
Aerosol particles are directed toward and deposit at the ductwork leaks because:
• All supply, return, and exhaust grilles are temporarily sealed, so all the airflow passes through the ductwork leaks.
• Small Aerosol particles are kept suspended in the airflow by continuous air movement.
• As the air stream makes a sharp turn to exit through a leak, the particles collide with and adhere to the leak edges.
• Using adhesive solid particles allows the built-up seal to span leaks as much as 5/8 inch wide.
