The patented Aeroseal sealing process is the most effective, affordable, and viable method of sealing the central heating & cooling and ventilation ductwork in residential homes and commercial buildings.
The air sealing system results are guaranteed for 10 years for residential homes.
The Aeroseal 6-step process takes very little time to bring you big savings and comfort:
- Wall registers are covered in order for air to escape only through the leaks
- Sealant in injected into the ducts for approximately 1 hour
- 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
- Ducts are sealed with only 1-2 oz. (30-60 ml) of the sealant material remaining in the ducts
- A computer-generated analysis summarizing your home’s or building’s amount of leakage is generated, providing verification of success of the process
Sealing the air duct system in your entire home typically takes only 4-8 hours. You’ll immediately receive energy savings and a noticeable improvement in home comfort. Sealing process in commercial building depends on the leakage in the duct work and specific air flow or ventilation problem.
The Aeroseal duct sealing system effectively seals residential homes and commercial building’s ductwork from the inside by using a UL tested and approved sealing material. It’s clean, safe, and guaranteed for 10 years in residential application.
- The amount and percentage of air leaking from the ductwork and other air flow or ventilation problems.
- Inconsistent temperature variations throughout the home or building.
- Air flow levels for each room.
- Backdraft and combustion safety hazard potential for fireplaces, furnaces, and gas heater rooms and closets in residential homes.
- Manual repair needs of air duct system.
In an air duct diagnostic, a certified technician inspects and evaluates your central air duct system and recommends ways to maximize your savings and improve your home comfort or improve building efficiency and solve air flow / ventilation problems.
Major factors during inspections are construction practices, type of duct work, age of the home / building, hot or cold or stuffy rooms, Indoor Air Quality (IAQ) problems, high energy bills etc.
Our trained and certified technicians use computer-based tools and reports to gather information about duct leakage and register airflows.
To start the Aeroseal duct sealing process, all room, ceiling or 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 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.
Once the Aeroseal air duct sealing is complete, the technician 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 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.
Aeroseal can reduce duct leakage by up to 90% and save a typical homeowner up to $850 a year in energy costs and a typical building up to 30% of HVAC energy use.
The measured result of a typical Aeroseal air duct sealing process is shown below:
Aeroseal provides a solution to:
- High energy bills
- Air flow and air balance issues in commercial buildings
- Uneven temperatures resulting in hot and cold rooms in residential homes
- Excessive humidity and dust
- Musty odors or fume smells and other ventilation problems
- Aeroseal can reduce duct leakage by up to 90%, and save a typical homeowner up to $300 a year in energy costs and a typical building up to 30% of HVAC energy use.
- Residential Leaky ductwork sealing improves the performance of heating and cooling systems, making a homeowner more comfortable by:
- Cooling or heating the house more quickly
- Delivering more hot or cold air
- Distributing heating and cooling more uniformly throughout your house
