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.
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.
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.
Aeroseal is guaranteed for 10 years. That doesn't mean the process will fail after 10 years. It has been stress tested for 40 years in residential applications
There is a very mild odour similar to Elmer’s Glue during the sealing process. The odour will dissipate completely by the next morning – but usually before.
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.
It only takes around 2 hours for Aeroseal sealant to dry.

Up to a 5/8th inch or 1.6 cm round hole can be sealed by Aeroseal.
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.
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.
Extremely dirty ducts should be cleaned. We recommend that a technician from Ashton Heating and Cooling assess the condition of ducts prior to beginning to Aeroseal process.
Ducts of all material types can be successfully cleaned after they have been sealed with Aeroseal.
