Inspection discovers any obvious break in the duct work and, as the initial step of the sealing process, the Aeroseal system will establish an exact amount of leakage in the duct system. Of course, many people already know that a room or two in their house doesn’t get good air circulation because they can feel it. Or they already know that their energy bill is high because they see it. The diagnostic measurement provides a scientifically valid means to understand the performance of your air duct system.

Some homeowners have saved up to 40 percent on their energy bill. Naturally, exact savings are difficult to precisely estimate since they depend on a multitude of variables such as your weather, house condition and design, your heating and air conditioning system, system usage – as well as other factors like energy prices.

Aeroseal duct sealing works in the following ways:

• Preseal test to measure the leakage as a baseline for measuring progress.
• Block off the registers with foam or plastic.
• Inject an UL tested and approved aerosol into the duct system.
• Since the air has no place to go except out through the leaks (the registers are blocked), the sealant material is deposited precisely at the air duct holes or cracks where leakage occurs.
• A computer and sensors are used to measure and control the progress. The technology is patented from the University of California and the process is endorsed by the Environmental Protection Agency.
• Postseal test to measure improvements.
• Complete report and certificate printed on the spot to provide a record of improvements.

The vinyl sealing material remains rubbery, never cracking.

The sealing material has a 10 year warranty and an expected lifespan of over 40 years

It’s likely that the holes and cracks in the ductwork have allowed dust and other particulate matter to enter the system. If you are experiencing extensive levels of household dust, this might be the reason. In most instances, duct cleaning is not found to be required prior to Aeroseal sealing. Your Aeroseal contractor can advise whether it will be necessary to clean your ductwork prior to sealing.

Ducts of all types can be cleaned after Aerosealing.

Unlike other sealing methods, Aeroseal can seal ducts that are hidden. Aeroseal can seal all types of ducts.

The sealant only sticks to the holes in the air duct without coating the rest of the duct.

The sealant material consists of a water–based solution (65 percent water) prior to application. The dried sealant material primarily contains two chemicals, vinyl acetate polymer (VAP) and 2–ethyl–1 hexanol (2E1H). The vast majority of what is left in the duct system is VAP, which has been used in water–based paints, adhesives, and hair spray. VAP has been used in chewing gum and baby pacifiers, and has no OSHA Exposure Limit. 2E1H is a common industrial solvent and is not considered toxic by OSHA. A review of the literature showed no ill effects after long–term exposure to concentrations of 200 ppm. The largest concentration of 2E1H measured in test houses was 1 ppb (200,000 times smaller), during Aeroseal injection. The sealant is UL–listed for smoke generation and flame spread (UL 723 0,0), and additional testing by UL showed no signs of mold growth or erosion.

At the time of application there is a very mild odor, similar to that of craft glue. However, that dissipates within a few hours. The Aeroseal air duct sealing process leaves no lingering odor, and since the material does not put off gas over time, there will be no odor for the life of the product.

The Aeroseal sealing system can help improve the comfort of your home by reducing the difference in temperature levels throughout your home.

Some homeowners have saved up to 40 percent of their energy bills after having the Aeroseal air duct sealing system seal their central air duct system. A typical homeowner should expect to see measurable reduction in energy use for heating and cooling.

Ductwork runs through attics, crawlspaces, basements, garages, and walls. Leaking return air ducts pull in dust and other indoor air pollutants and sends them to the central heating and cooling system. From there they sent to the living areas of your home. The Aeroseal air duct sealing system can reduce the amount of leakage by as much as 90 percent, reducing dust and other indoor air pollutants from the conditioned air in your home.
