How Does Aeroseal Duct Sealing Really Work?

Aeroseal Duct Sealing prevents air from escaping through duct work holes in residential and commercial buildings. Tiny beads of non-toxic vinyl acetate polymer particles collect in torn ducts with a maximum 5/8 of an inch hole. The particles stick to the edges of the tear and then to each other until the leak is sealed completely. Aeroseal’s patented technology comes with a 10-year guarantee.

While a little over a half-inch does not sound like a major tear, the crack in the ducts of a heating ventilation and air conditioning system (HVAC) can account for major losses in the warm or cooled air circulating through a home or commercial building. Duct sealing is necessary for comfort and energy savings.

Finding the leaks is not so easy…fixing them is!

Air leaks are difficult to locate. Duct cracks are often sealed with tape and glue when they are finally discovered. These are not lasting seals and the air forced through the ducts may eventually destroy the tape or glue.

You know there is a problem with your HVAC system when your utility bills are higher. Heating in the winter and cooling in the summer can account for up to 40% of your energy bill. Air leaks will raise the cost since the HVAC system has to work harder and use more power.

A clue to the location of a leak may come when one room stays warm during the winter while another seems impossible to heat. Or, you may have a reverse situation during the summer. The ducts supplying air to those rooms may have small leaks. This does not mean that your entire system must be replaced.

Excessive dust, dander, pollen and even exhaust from gas appliances will be in the air, especially when there is a leak with the intake ducts. The particulates may not be carried all the way to the filter system.

Trained Aeroseal technicians will seal off vents for a short time with a foam. This forces air through the leaks in the ducts. This Air Duct Diagnostic pretest will detect the leaks in the duct system. This may be 30% to 40% of the air circulating through your HVAC system.

Air conditioner coils, fans and furnace are temporarily blocked while the sealant is injected into the system. The circulating air will carry the liquid to the cracks where it will adhere and become a solid substance. It does not cover the ducts.

A technician can determine how much air is leaking and the size of the leak with this test. If the leak is larger than 5/8 inch in any location the procedure is stopped and other remedies are considered.

Preparations make all the difference in Aeroseal Duct Sealing!

Dirty ducts should be cleaned before Aeroseal Duct Sealing is employed. Otherwise, the only preparation necessary involves covering any electronics in the area where the substance may be applied.

There is a mild odor similar to Elmer’s glue that may prevail for about two hours after the sealant is applied. Residents are advised to leave the house if they are sensitive to odors.

A computer analysis will give you the results along with a printed certificate showing the time and date the ducts were sealed.

Take advantage of Aeroseal Duct Sealing to keep your HVAC system in peak performance while saving on your energy cost.
