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 nondestructive – The unique sealing process is done from the inside so leaks that are hard to reach, under insulation, or in tight spaces will be tightly sealed.  And we don’t need to cut through any drywall!
  • Duct sealant is proven safe – The sealant is completely non-toxic, low-VOC certified and UL listed. It smells a bit like Elmer’s glue, but the mild odor is usually gone within a day.
  • Duct sealing is warranteed – A 10 year warranty is included, but it has been stress-tested to last for over 40 years.
  • Duct sealing creates a healthier home - Sealing cracks and holes in ductwork prevents the spread of harmful particulates from being circulated to living and work spaces.
  • Duct sealing helps protect the environment – Aeroseal reduces energy use, reduces energy waste and lowers carbon emissions for a cleaner environment. (More facts are available at Aeroseal’s FAQs page)

The Benefits of Aeroseal

Even, Consistent Temperatures = Better Comfort

Cracks or leaks in ductwork systems will prevent an even flow of hot or cold air from reaching rooms in your home. By sealing duct leaks, air pressure/flow will be stronger and more equally distributed, while your home becomes more evenly heated and cooled.

Healthier Indoor Air Quality = Fewer Allergy Symptoms

According to EPA research, leaky ductwork in attics, unfinished basements, crawlspaces, and garages can spread dirt, dust, moisture, pollen, pests, and fumes throughout homes and buildings. Studies have also shown that 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, fewer allergy and asthma symptoms, and breathe easier. See more about the benefits of Aeroseal in a recent article 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

The Department of Energy has conducted studies in the Chicago-area and has found that 25-40% of the conditioned air in our homes is being lost through duct leaks! That's 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 feel comfortable or be energy efficient if the ductwork is leaking.

Priority Energy’s certified Aeroseal technicians will provide reliable and effective duct sealing for your residential or commercial project.

  • 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.

    Executive at Medline Industries, IL
  • 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.

    Bill; Belvidere, IL
  • 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.

    Bryan, November 2019, Chicago, IL
  • Priority Energy did a great job with an Aeroseal project for my home. The rooms are more comfortable and even throughout the house, including the far registers which never used to get significant airflow. Very honest and trustworthy

    Bryan, December 2019, Chicago, IL

  • I had Priority Energy analyze my older home for indoor air quality and comfort because I was having difficulty maintaining temperatures. They came out and discussed our options. We ended up sealing our ducts and installing a whole-house dehumidifier.

    D. L, Lake Zurich, IL Feb. 2019
  • Priority Energy did an aeroseal for our home. We have had issues with air flow in our kitchen (cold in the winter) and one bedroom upstairs (hot in the summer). After they were complete, there is such a stronger air flow from the vents, that it really makes a difference.

    J.J. Chicago, IL - November 2020
  • Excellent Service and Company to work with - highly recommended and professional!

    T. B. Chicago, IL - July 2020
  • Before we sealed our ductwork the rooms farthest from the furnace were always hotter or colder than the rest of the house. We felt an improvement in air flow to the kids rooms right away. 98% duct leak reduction!

    S. H. Glenview, IL - October 2020
  • The Energy Audit you did on last home was so helpful; we referred to it for years when we made home improvements. I'd like to have you do an audit on my new home now. B. A.
