What is Aeroseal?
Aeroseal is a patented breakthrough technology that tackles duct leaks from the inside out. The Aeroseal process puts escaping air under pressure and causes polymer particles to stick first to the edges of a leak, then to each other until the leak is completely sealed.
Aeroseal is the best duct sealing solution available.

Commonly Asked Questions
The Aeroseal process does not coat or line the ductwork. The only sealant remaining in the ducts will be at the spot of the leak that was sealed.
This noise is usually the result of two conditions. One is created when the ductwork is undersized and air is rushing through your air duct system. The other condition is caused when a limited amount of air is allowed to flow through the indoor coil of your heating and cooling system. Once the exact problem has been identified, your contractor can provide the best solution for noise reduction.
Ducts of all material types can be successfully cleaned after they have been sealed with Aeroseal.
Dirty ducts should be cleaned as we can not guarantee that the glue will adhere to dust and debris. We will inspect the ductwork during the Aeroseal estimate.
Aeroseal certified technicians are trained to protect all HVAC systems and accessories prior to sealing. Some items, such as humidifiers or UV lights, may be removed then reinstalled to prevent damage. Others may be bagged or covered.
We recommend that any sensitive electronics be covered while Aeroseal is sealing your ductwork.
Sealant escaping from the ducts will settle in wall cavities, attics or crawl spaces. During the process we will filter the air to capture any sealant entering any living areas.
Broken and disconnected ducts – large leaks – need to be fixed prior to sealing with Aeroseal. If a hidden large leak is uncovered during sealing, the process is stopped and a solution is discussed.
Up to a 5/8th inch round hole can be sealed by Aeroseal.
We prefer that no one is in the house during sealing due to impact on productivity.
If you are pregnant, a senior, infant, or utilizing medical equipment we do encourage you to leave as a simple safety precaution.
The sealant used by Aeroseal has been tested by an independant lab and found to have extremely low concentration of VOC’s during sealing time.
The primary componont has NO OSHA maximum exposure limit.
It only takes around 2 hours for Aeroseal sealant to dry.
Sealant used by Aeroseal is non-toxic and has been used in hospitals, surgery centers, and government institutions.
UL approvals for UL 1381 for aerosol based technology – UL 723 for smoke and flame rating of 0 and UL 181 for mold growth.
Primary component is Vinyl Acetate Polymer, used in water based paints, hair spray, and chewing gum.
There is a very mild odor similar to Elmer’s Glue during the sealing process.
The odor will dissipate completely by the next morning – but usually before.
Aeroseal is guaranteed for 10 years and stress tested for 40 years in residential applications.
A series of government reports have shown that air duct sealing can lead to up to $850 in energy savings per year.
Some homeowners have saved up to 40% 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
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. Many people are surprised to learn that homes typically leak 30% to 40% or more of their air through air duct leaks.
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 are 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%, reducing dust and other indoor air pollutants from the conditioned air in your home.
By sealing your ductwork utilizing the Aeroseal technology you can expect air to be delivered where it is designed to go and not into your not basement, attic, or crawl space.
This reduces hot or cold spots in rooms and between floors.
The sealing technology was invented by Dr. Mark Modera, a scientist at the University of California, in 1994.
History of Aeroseal
The technology was developed and tested by Indoor Air Quality scientists within the Indoor Environment Program at Lawrence Berkeley National Laboratory.
The University of California was granted patents in 1996 and 1999, and Aeroseal holds an exclusive license to the technology.
In 1997, the magic began to happen. HVAC contractors officially began using the Aeroseal technology to effectively seal air duct leaks in homes and commercial buildings, and the occupants have been noticing improved comfort, reduced dust/allergens, and lower energy/utility costs ever since.
The Aeroseal sealant has been in use for over twenty years. It is a vinyl material that is suspended in a water solutions. Once atomized, the sealant is air dried and is deposited principally at the leaks without coating the inside of the ducts.
In 2000, The Department of Energy (DOE) and its Citizen Judges selected the 100 best scientific and technological accomplishments to come out of the 23 years of the DOE’s existence. The Citizen Judges narrowed down the field to the 23 technologies that have the largest potential to save consumers money and improve their quality of life. Aeroseal duct sealing technology was selected to receive both awards.
Upon the arrival of 2017, Aeroseal made some game-changing moves. It celebrated its 20th anniversary, announced its new product AeroBarrier, the breakthrough envelope sealing technology, and became a member of the Home Builders Association of Dayton (HBA).
