Aeroseal Duct Sealing: What Is It? What Are Its Benefits?

Three-quarters of American homes have an air conditioner. About 6% of the electricity produced in the US goes towards running those HVAC systems.

Many of these HVAC systems use more electricity than necessary. This is because they are not well maintained and may have leaks in the ductwork.

Aeroseal duct sealing can address the issue of leaks. This can result in several benefits beyond reduced energy usage. If you aren’t familiar with Aeroseal and its benefits, this article will explain everything you need to know.

What Is Aeroseal Duct Sealing?

The ducts are a part of your HVAC system that transports the cold and hot air throughout your home. Aeroseal seals the leaks in the system by releasing an aerosolized sealant fog into the system.

As the particles in the fog reach the leaks, they stick to the edges of the hole. Then the particles begin to build on each other to eventually seal the cracks.

The particles can fill cracks that are up to 5/8th of an inch wide. The process will take about four to eight hours to seal all of the ductwork in your home. Once sealed, the Aeroseal can last for up to 30 years.

The Benefits of Air Duct Sealing

There are several benefits to having your ductwork sealed with Aeroseal. Unlike other sealing methods, Aeroseal approaches the task from the inside of the duct. The process will be more thorough and faster.

It can also address leaks in the system that you don’t know about or are in hard to reach places.


When there are leaks in your ductwork, you’re getting robbed of the hot or cold air that’s supposed to get circulated throughout your home. This can result in uncomfortable areas or rooms of your home.

Once you have an HVAC duct sealer applied, your home becomes noticeably more comfortable. You’ll no longer lose the air to your attic.

Indoor Air Quality

Sealing your air conditioning ducts will reduce the possibility of dust, pollen, mold, and dander from getting into your HVAC system. This will also prevent them from circulating throughout the system. While sealing your air ducts doesn’t solve the air quality problem on its own, it does play a big part in maintaining clean air.


Sealed ducts can actively protect your home. If mold spores get into the system, they can travel throughout your home. Eventually, they’ll end up in a place where they will thrive.

Once this happens, you could have mold, mildew, or bacteria multiply and spread throughout your home. This can create serious medical complications for you and your family.

Once you seal your ducts, those potentially harmful spores get directed through the system to the filter. They then become trapped and can no longer pose a threat.

Save Money

When you have a sealed ductwork system that doesn’t have wastage, your system doesn’t have to work as hard. This means it’ll use less energy to cool or heat your home. The less energy your HVAC system usages, the lower your bill will be.

This makes the Aeroseal cost well worth the one-time investment.
