Comfort and Savings Year-Round!


Aeroseal Fast Facts

  • Duct sealing is fast – Sealing ducts in new construction takes only a few hours. Existing homes take some time to set up, but are still usually finished in only one day. 
  • Duct sealing is easy and nondestructive – The unique sealing process is done from the inside so even leaks that are hidden behind walls, under insulation, in tight spaces or in other inaccessible places are tightly sealed.  And we don’t need to cut through drywall.
  • Duct sealing is safe – The sealant is completely non-toxic, UL listed and approved and Low VOC certified. It smells a bit like Elmer’s glue, but the slight odor is usually gone within a day.
  • Duct sealing is guaranteed – A 10 year warranty is included, but it has been stress-tested for over 40 years of durability.
  • Duct sealing helps protect the environment – By reducing your energy use/waste and lowering the amount of carbon emissions leaking to the outdoors, our environment will be a cleaner place for our future. (More facts are available at Aeroseal’s FAQs page)

The Benefits of Aeroseal

Even, Consistent Temperatures = Better Comfort

Cracks or leaks in ductwork systems can prevent the steady flow of hot or cold air from reaching rooms in your home. By sealing the leaks, more even airflow will be maintained and your rooms will feel more comfortable, with reduced drafts and more consistent temperature.

Healthier Indoor Air Quality = Fewer Allergy Symptoms

According to the EPA, leaky ducts in attics, unfinished basements, crawlspaces, and garages can allow dirt, dust, moisture, pollen, pests, and fumes to enter the home, and back drafts from heating and cooling sources can circulate h

armful CO gases. By sealing duct leaks, you can greatly improve your indoor air quality and have less dust, reduced allergy and asthma triggers, and a much safer home. See more about the benefits of Aeroseal in a recent feature in North American Builders magazine.

Healthier Indoor Air Quality = Effective Radon Mitigation

Duct sealing can help reduce high radon levels. We've used Aeroseal on leaky ducts in the slab where the gas can easily seep into a living space. Within a few hours of sealing the duct leaks the radon level was no longer harmful and the indoor air was healthy.

Better Energy Efficiency = Lower Utility Costs

We’ve seen it work in thousands of homes, but don’t take our word for it. The Department of Energy has proven Chicagoland homes lose 25-40% of their airflow through duct leakage!  That means over a third of the conditioned air we are “paying for” never actually reaches our living spaces. Even the most high-performance HVAC system won’t make your home comfortable or save energy if the ductwork is leaking.

  • Thank you again and you will be the first person I call if I need additional part or service from your company.
  • I just wanted to send this message to all you and say GREAT JOB!  We had a rough inspection today and passed for the Woodward Ave. house. The inspector told us "if every house I inspected looked like this one I would be out a job".

  • We were so impressed with the amount of information the Priority Energy technicians gave us during our ENERGY AUDIT.  If you are buying a house, I would strongly recommend having them do an energy audit on it, in addition to your usual home inspection.

  • Thanks for a super intelligent and deep seminar expertly handled by a staff which was a pleasure to be around. Lunch was superbly and subtly handled.

  • I have a two story home built in the mid seventies. Lots of temperature fluctuation between the floors. The Aeroseal process dramatically increased the air flow to the second floor. Good experience. The company was very informative, answered a lot of questions.

  • Duct sealing (with Aeroseal) was the smartest thing I ever did! Our home is sooooo much more comfortable! We were so very pleased with Priority Energy and their technicians!

    Richard; Lake Forest, IL
  • On to the Radon issue - Excellent results with Aeroseal!  From 5 + to a .4.  Before sealing like we discussed, I had warm air coming out of the sump basket with the furnace running. Even with the furnace running, it is still pulling air in now.

  • Pat was awesome and super helpful! We are experiencing weak air flow in the duct system of our 1950''s home and Pat gave us great recommendations to fix the problem when we do our remodel.

National news outlets recently reported that the EPA's Energy Star program recommended "new drastic temperature settings" for home thermostats. We searched the internet and could not find a credible source for this information and so turned to Energy Star directly, for more information.
