What Home Owners Are Saying

I spent about 23 hours of my own time really getting at every nook and cranny sealing my duct work that I could by hand—with little effect. Then Aeroseal came in and it took less than a day to really fix the problem.
Tim
The best part is that the house smells so much better now that the disgusting air is no longer being pushed out through disgusting coils/vents. Seriously—after they left and the A/C came on it was a night and day difference.
Alyssa P.
I’ve seen a noticeable improvement in my system’s performance in a few ways; less running time to heat home (despite it being consistently -10 degrees outside each day), and each room feels more evenly heated.

Aeroseal Dirty Ducts

Yuck, Why Is There So Much Dust Build Up?

Good question, but before I get to that, you may not even know how much it's affecting air quality in your home until you FEEL the difference.

So different that you forgot what it was like when parts of your house were getting too hot while others were getting too cold.

So different that you're breathing through the night and waking up ultra-refreshed with clear sinuses.

So different that your next energy bill is 40% less.

Most Ducts Leak, Causing The Buildup In The First Place

AND, 40% of the money you spend on heating and air doesn't even reach your living spaces—it just leaks out of the home.

AND that's why your home has cold spots and hot spots, causing you to migrate throughout the day to different rooms.

Cold Spots & Hot Spots

You might be thinking "how can I really know that's what's happening?"

Just ask yourself, how often do you dust your furniture (or should be)?

And also, it's just a fact that 95% of homes in the U.S. have leaky ductwork.

95% of homes have leaky ductwork

BUT it's not just dust that's seeping in.

Have you ever walked past a part of your house, get a whiff of something foul as you stroll by, then double back to find the source only to be left wondering what that was?

Your ducts travel through some pretty yucky places like attics, crawlspaces, and interior walls, which supply leaky ducts with allergens, smelly odors, and moisture.

And sometimes those odors just waft into your living spaces uninvited. Rude.

90% of your life is spent indoors—breathing all that in.

This is going to sound extreme, but this is from Harvard and the EPA.

Poor indoor air quality can lead to Sick Building Syndrome, a chronic condition with symptoms ranging from headaches, eye, nose, and throat irritation, fatigue, dizziness, and nausea.

In addition to that level of discomfort, it can lead to reduced productivity and impaired learning.

We don't want that to happen to you.

Sealed Ductwork Makes A Night-And-Day Difference

I’m breathing much easier and not waking up congested in the middle of the night. I would wholeheartedly recommend Aeroseal for your A/C and ductwork needs.
Melinda R.
The temperatures throughout my home have felt much more balanced since they were aerosealed. The force of the air coming from the problem vents has increased substantially, and my furnace and AC now run less.
Erik B.
My house is now my fortress and my refuge. They found a solution to a problem that several doctors couldn't solve.

Frequently Asked Questions (FAQ)

Can you fix my hot and cold rooms?

Yes! Sealing your vents and ducts means that air is delivered where it’s needed, and not into your basement, attic or crawl space. This also helps get rid of hot and cold spots in your house.

Will this help my house be less dusty?

Absolutely! Leaky ducts and vents pull in dust, mold and dander and then blow them into living rooms, bedrooms, and kitchens. Gross, right? Our system can reduce leaky areas by as much as 90%, making sure dirt isn’t circulated in your house.

How much can I save on my utility bill?

A lot! Independent government-sponsored studies have shown that sealing your ducts can save you up to $850 per year! Most homeowners save at least 20%, some save as much as 40% of their total bill. Exact energy savings are difficult to predict, since they depend on where you live, how old your house is, how up to date your system is, how many rooms you need to heat or cool, and how energy costs are calculated in your area.

What is the sealant material made of?

Primary component is Vinyl Acetate Polymer, used in water based paints, hair spray, baby pacifiers, and chewing gum.

Is your formula really safe for my family and my pets?

Without a doubt. Our formula is safe, non-toxic and water-soluble, made of the same material that is found in chewing gum and baby pacifiers. It is so safe, we’ve helped hospitals, surgery centers, schools and public buildings make sure their air is clean, healthy and comfortable – and saved them energy and money in the process.

How long does it take to dry?

Drying time is less than 2 hours.

Will my house smell?

There is a mild odor, like Elmer’s Glue, during sealing. Odor should dissipate by next morning (or before).

Should I leave my house during the service?

We prefer no one is in the house during sealing due to impact on productivity. If you are pregnant, senior, or infant, or utilizing medical equipment we do encourage you to leave as a simple safety precaution.

How big of a leak can your sealant cover?

Aeroseal is able to close most cracks and leaks in most air duct systems. Any large, major leaks—like broken, disconnected or damaged ducts—will need to be repaired prior to sealing. Most of the time, we uncover problems like this during our initial inspection. However, if we find this during our sealing process, we will stop our service and recommend a solution.

How long does this stuff last?

We guarantee our work for at least 10 years, and we’ve stress-tested it up to 40 years in homes. We expect your heating and cooling systems to work efficiently for as long as you own your home.

Where does the sealant leaking from the ducts go?

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 the living areas.

Will it harm electronics?

We recommend sensitive electronics be covered.

What about my HVAC accessories? Will it harm them?

Technician is trained to protect all 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.

Does my ductowork need to be cleaned first?

Sometimes, but not always. Any ducts that are extremely dirty should be cleaned first. We find this most often in older houses. Our technician will take a look at this during the initial inspection, and recommend a cleaning if needed.

If I have my ducts sealed, can they be cleaned in the future?

Yes. Ducts from all types of materials can be successfully cleaned after being sealed. Our formula dries into a very hard, very durable substance.

Will all the insides of my ductwork be coated with sealant?

No. Our formula doesn’t coat or line your ducts. The only sealant remaining after our technician is done will be over the leak that was sealed.

How does it work?

Duct sealing, utilizing the patented Aeroseal process, takes a non-toxic liquid sealant, heats and dries it to become an aerosol mist. The mist travels through a pressurized duct system and seals visible, invisible, and inaccessible leaks in the system. We guarantee it and it is certified.

How do I know if my ducts leak?

According to the Department of Energy 95% of homes in the U.S. have leaky ductwork and they leak between 25% and 40%. In simple terms, that means air is not getting to designed spaces causing hot/cold spots in the house, excessive dust, and high energy bills.

How much does it cost?

Pricing is based on square footage and other factors. See our Pricing Page for details.
