Aeroseal Duct Sealing


Aeroseal is a duct sealing process developed & patented by the US Dept. Of Energy & Environmental Protection Agency to combat wasted energy, poor air distribution,  indoor air quality, (IAQ) problems caused by air duct leakage.  These problems are typically blind to most homeowners who have come to accept excess dust, uneven cooling or heating of rooms, & IAQ symptoms associated with “sick home syndrome” as normal and not connecting these problems as the result of leaky ducts. Until Aeroseal there was no cost effective way to seal existing duct work in homes because most duct work is concealed in walls & other hard to reach places. Aeroseal works from the inside using a non-toxic aerosol process that seals only the gaps & cracks reducing leakage, in many cases over 90%. Greene Solutions LLC is a licensed dealer of Aeroseal.


Uncomfortable hot or cold rooms
Unsealed gaps and leaks in your duct system allow treated air to escape into crawlspaces, attics, and walls preventing the air from being delivered to its intended destination.
Excessive dust
Leaky ducts pull mold, dust, and other pollutants into your home presenting indoor air quality issues and aggravating existing asthma and allergy problems.
High energy bills
On average, 30 cents of every $1 you spend on heating and cooling your home or building disappears into thin air due through leaky ducts.
Excessive humidity
Small gaps and holes in your duct work draw humid air from the outside into your home creating humidity and comfort issues.
Musty odor or fume smells
Leaky ducts contribute to safety issues in residential homes due to potential back drafting of gas appliance fumes, auto exhaust, and radon gas into your living space.

How Aeroseal Works

Step 1.. The inspection and pre leakage test. We will temporarily block all supply and returns and run the pretest.  This will tell us how leaky the duct work is in square inches and in CFM (cubic feet per minute).

Step 2.  The sealing.  We will then begin sealing the duct work with the computer operated Aeroseal patented aerosol mist.  The ducts are put under positive pressure and where air leaks from the duct work the mist seals the leak from the inside (does not coat the duct, just fills the leak).

Step 3. The post leakage test. With the supplies and returns still blocked, we will run a post leakage test that will tell us how much of a reduction in leakage there was and your projected energy savings.

Step 4. The printed report.  We will then print the report with the pre-leakage results, the post leakage results, and your projected energy savings.



Frequently asked questions

What amount of leakage reduction is expected?
We have seen leakage reduction up to 90%.

My ducts are wrapped in insulation, doesn’t that keep them tight?
Air ducts are not sealed by the insulation wrap and often this insulation only hides poor metal work assembly or disconnections that are discovered during our leak testing.

Does Aeroseal coat the duct work?
No, it only fills the leaks in the duct from the inside.

Is Aeroseal harmful in any way?
Aeroseal has a zero OSHA maximum exposure limit, & is made of the same materials used to make baby pacifiers, so it is non-toxic.

How long does it take to do the sealing?
Depending on the size of the home, but usually in one day. Once we are done the system can be used.

Do you need to open walls?
No!  We are able to reach all of the duct work without opening walls, cutting holes in ceilings, and any other areas that are concealed.

What is the warranty?
The product has a 10 year warranty for residential properties and at the end of each Aeroseal a certificate of completion is generated certifying the amount of leakage before and after the process along with the equivalent size hole in inches and percentage.
