What Is Aeroseal and Is It Right for Your Ducting?

By Aztil –

Image for What Is Aeroseal and Is It Right for Your Ducting?

According to the National Renewable Energy Laboratory (NREL), HVAC air ducts can lose up to 40% of an HVAC system’s heating and cooling energy. This remains true even when air ducts are relatively new and well-maintained. Duct sealing cuts these losses by eliminating air leaks. Although mastic sealant and duct tape are certainly advantageous to this end, nothing trumps the efficacy of Aeroseal. Hailed by the United States Department of Energy (DOE) as one of the best technological and scientific advancements since the DOE’s inception, Aeroseal can reduce duct-related energy waste by as much as 30%.

What Is Aeroseal?

Developed in 1994 at the Lawrence Berkeley National Laboratory and comprised of the same materials used in chewing gum and pacifiers, Aeroseal is a completely non-toxic and high-performing duct sealant that HVAC companies install via air vents. It adheres to cracks, gaps, and other air leaks in duct materials measuring just 5/8″.

After injecting Aeroseal into ducting, HVAC technicians pressurize air ducts to draw Aeroseal toward air leaks. When it reaches structurally compromised areas, it forms tight, impenetrable seals that could last for up to 40 years. Given that the average lifespan of HVAC ductwork is just 15 to 20 years, a single application of Aeroseal is more than sufficient.

What Are the Benefits of Using Aeroseal?

Aeroseal outperforms both duct tape and mastic sealants by forming a surer and longer-lasting bond. Duct tape adhesives tend to fail over time as ducting collects dust, oils, and other debris. Mastic sealants must be paired with fiberglass mesh tape to ensure lasting success. Not only are mastic sealants messy,  but they aren’t easy to apply in all areas.

Comparatively, Aeroseal offers the least invasive installation method and the best overall results. With Aeroseal, you can seal leaky ducts in remote, hard-to-reach locations such as basements, attics, and crawlspaces. You can also treat concealed ductwork without having to cut into drywall or remove other structural barriers.

Save Money

With Aeroseal, more of the heated and cooled air that your HVAC system produces will be distributed throughout the building. Not only will this lead to lower energy bills, but it can also extend the lifespans of heaters, air conditioners, heat pumps, and ducting. It does so by limiting stress throughout HVAC systems and optimizing airflow. You’ll pay less for HVAC repairs throughout the years, and you’ll have more time to plan for HVAC replacements.

Improve Indoor Air Quality

Leaky air ducts allow conditioned air to escape. However, they can also take in air from dusty areas and distribute it. This is the air that never passes through your HVAC air filter, and it often comes from crawlspaces, attics, and other dirty, mold-prone areas. Aeroseal will boost your indoor air quality (IAQ) by ensuring that all of the air routed throughout the building has had dust, lint, hair, carpet fibers, and other common airborne particulates removed.

Enjoy Greater Home Comfort

By optimizing airflow, boosting IAQ, and supporting efficient HVAC performance, Aeroseal can also improve your home’s comfort. You won’t have to contend with hot and cold spots throughout your home or business when leaky air ducts aren’t depositing conditioned air in your basement, behind your drywall, or in other remote locations.

Is Aeroseal Right for Your Home or Business?

Aeroseal is the top choice for duct sealing in both residential and commercial applications. Sealing your air ducts with Aeroseal will result in immediate and ongoing energy savings. It will also improve residents’ comfort, improve your indoor air quality, and increase the service lives of all your HVAC equipment.

Your service techs and general service has improved since the corporate take over. Raphael Curci was efficient and kept us u[p to date on the progress of the installation. The person I'd like to call out as exemplary was Nico who guided us through the process and went out of his way to help us through this time.
Ramon explained in detail what he was doing and how to prevent issues. Ramon is a credit to Aztil. This a/c company has wonderful systems in place to protect their customers homes. Highly recommend Ramon as technician and Aztil for your a/c maintenance and repairs.
I LOVE this company and Nico is hands down the number one technician on the team. The maintenance plan is worth every penny and I never have a problem getting anyone out when I need them.
Toni did a fantastic job! I believe he also did a very thorough job in all areas of our AC unit. He advised us of some areas of our unit that was building up mold and what needed to be done. The concern I had was why no other techs that come out every 6 months hadn’t brought this to our attention. Toni is very personable and he took the time to explain everything to us and I could tell that he is concerned about customer satisfaction. Appreciated all his efforts. Excellent Tech! We will request him to come back in 6 months again!
Michael performed well and was very friendly.
Cody was extremely professional and very courteous!! His knowledge and expertise takes him a 10 plus!! When I call Aztil I only want him to service my AC..
Thank you Aztil for sending Cody for my repair. He is an asset to your team!!
