 Forecasters predict a cold winter and higher natural gas prices this winter. Sealing leaky ductwork can lower heating costs and reduce energy waste year-round.

The heat you are paying for may be getting lost behind your walls through cracks and holes
in your home's ductwork. 
Uneven room temperatures and poor air flow are often signs of duct leakage.

Did you invest in a new furnace or central air cooling system?
Keep in mind that even the highest AFUE-rated furnace will not heat
your home efficiently if the duct system is leaking and loosing conditioned air. 

You deserve a healthier, more comfortable and energy efficienct home.

Get an "inside" look at your home's duct system.
Schedule a duct leak assessment today by calling 1.312.767.9047.

There is a small fee for this assessment which can be applied toward the duct sealing service.
No high pressure sales, only information. We promise!

 We use an Infrared camera to scan your duct work. Any hot or cool air loss from duct leakage will be visible with our camera. We also measure air pressure in various rooms as duct leaks reduce air flow and cause uneven heating and cooling throughout a home. Our experienced energy auditors will advise you on the best "next steps" to help you improve your home; be it duct sealing, a full energy audit or other recommendation.

Duct sealing with Aeroseal's computerized injection system is the only duct sealing method that can seal all seams and cracks in every part of a duct system, even in tight, hard-to-reach spaces where tape and mastic can't be done. It is the quickest, most reliable method to seal ductwork and provides so many comfort, health and efficiency benefits that contractors everywhere are switching to this EPA-recommended duct leak sealing method. 

Highly effective in both new construction and existing structures, Aeroseal has been proven to help deliver better indoor comfort, healthier indoor air quality, more energy efficient heating and cooling and enhanced HVAC durability. Homeowners have saved between 20-30% on utility bills, carbon foorprints have been reduced and Aeroseal has even been successful at reducing radon levels in structures where ductwork is in the cement slab!

Aeroseal has been approved by the state of Illinois and the ICC as an acceptable duct sealing method for IECC code compliance in new construction. Most newly built homes have been successfully sealed in less than 3 hours; a fraction of the time once needed for traditional tape and mastic and it has been guaranteed to last 10 plus years! 

Priority Energy has performed over a thousand duct sealing jobs for happy clients throughout Chicago and the Midwest and recently won the 2019 Aeroseal service award for the fourth year in row.  Their technicians are Aeroseal certified, as well as BPI certified, the nationally recognized building science designation.  They provide fast, reliable duct sealing for new construction, existing residential homes, townhomes, condos, schools, universities, commercial facilities, office buildings and more.

It is estimated that 20-40% of the conditioned air (which we are paying for)
is wasted due to leaky ductwork (EPA).

  • 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.

    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.

    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.
