Aeroseal FAQs


Aeroseal Duct Sealing: Frequently Asked Questions

Q: How much can I save on my utility bill?

Independent government-sponsored studies have shown that sealing your air ducts can save you up to $850 per year. Most homeowners save at least 20 percent—some save as much as 40 percent of their total bill.

Exact energy savings are difficult to predict since they depend on where you live, how old your home 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.

Q: Is your formula safe for my family and my pets?

Without a doubt. Our formula is a water-soluble organic compound. We have helped hospitals, surgery centers, schools, and public buildings be sure their air is clean, healthy, and comfortable—and saved them energy and money in the process.

You certainly can stay in your home while our professionals are working, but as a precaution, we do recommend pregnant women, elderly people, and those with any breathing difficulties not be present while we are sealing your ducts and vents.

Q: Will this help my house be less dusty?

Yes. Leaky ducts and vents pull in dust, mold, and dander and then blow them into living rooms, bedrooms, and kitchens. Disgusting, right? Our system can reduce leaky areas by as much as 90 percent, being sure dirt is not circulated throughout your home.

Q: How big of a leak can your sealant cover?

Holes bigger than 5/8 inches in diameter are too big for the sealant to bond to effectively. Any larger, major leaks—like broken, disconnected, or damaged ducts—will need to be repaired before the sealing.

In most cases, we uncover problems like this during our initial inspection. However, if we find this during our sealing process, we can easily pause the system immediately to stop the flow of sealant, inspect for the problem area, and provide an on-the-spot solution before resuming the sealing process.

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

No. Our formula does not coat or line the insides of your ducts. The only sealant remaining after our expert is done will be over the leak that was sealed.

Q: What does your initial inspection tell me?

On our first visit to your home, we will look for any obvious leaks in your heat and air system. We can calculate how much cold and hot air you are actually losing in places like your attic, your garage, and in between walls.

Many people already know they have hot and cold spots or their energy bills are higher than they should be. So our initial test helps you understand how well or how poorly your system is performing.

Q: Does your sealant emit any harmful fumes?

Our sealant formula is derived from a natural organic compound and is safe to breathe. It has been tested by an independent lab and found to have an extremely low concentration of volatile organic compounds (VOCs). Some say it has a small odor similar or comparable to Elmer’s Glue, which goes away within a few hours after completing the service.

Q: Will your formula do any damage to my air conditioner, furnace, or personal electronics?

No. Our certified professionals are trained to protect all of your home equipment prior to sealing. Our formula is delivered via a temporary access point. Some items, like humidifiers or UV (ultraviolet) lights, may need to be removed and then reinstalled as a precaution.

Or, these items may simply be bagged or covered. You don’t need to cover any furniture. Our experts will take care of all this for you.

Q: How long does it take for the sealant to totally dry?

It depends on how much ductwork you have and how many leaks you have, but generally about two hours.

Q: How long does this stuff last?

We guarantee our work for at least 10 years, and we have 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.

Q: 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.
