How Aeroseal works to keep your home Cleaner and More Comfortable

Sealing ductwork delivers more force to the heat and air conditioning registers throughout your home, because it stops heated or cooled air from being wasted through your leaking ductwork. The average home in the U.S. loses about 25 to 40 percent of heated and cooled air through leaks found throughout the home’s air duct system. As an added benefit, sealed ductwork decreases the amount of dust that your HVAC system circulates in your home every time your furnace or air conditioner runs.

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. See our FAQ’s.

Aeroseal has already been used in over 100,000 houses and it has even been used at the Mayo Clinic. The use of Aeroseal to effectively seal leaks in HVAC ducts is also a documented Success Story on the Department of Energy’s website.

Hot or Cold Rooms are a Common Problem with a Simple Solution:

People struggling with high temperature variations between rooms or floors might not realize most of their conditioned air is escaping through duct leaks instead of flowing into their living space! Leaks in your ductwork allow cooled or heated air to escape into your attic, basement, and crawlspace or even into your walls.

Home Comfort, the main reason home owners want Aeroseal


The #1 reason home owners want Aeroseal Home Duct Sealing is because they experience hot and cold rooms or high temp differences between upstairs vs downstairs living areas. The majority of homes we see suffer from these issues due to leaky duct work not delivering conditioned air where it is meant to go!

Indoor Air Quality and Home Safety

Many home owners notice dust collection around registers and higher than average dust collecting on surfaces throughout their homes. Leaky ducts pull dust, mold, and other pollutants into your home, presenting indoor air quality issues and creating and/or aggravating allergy problems.

Energy Savings and Lower Utility Bills

Nearly 50% of the average home's energy bill is spent on heating air conditioning and ventilation. Duct leakage in residential homes costs consumers $25 billion each year. On average, 30 cents of every $1 you spend on heating and cooling your home or building disappears into thin air due to duct leaks.
