Priority Energy, Aeroseal for existing homes, IL

Rooms too hot or too cold? Allergy symptoms?

Small holes and cracks develop in older ductwork as mastic and traditional sealing methods age. Today, over 90% of the country’s existing homes and buildings have leaky ducts. The amount of air leakage depends on the type of construction, the type of ductwork and the IECC building code that was enforced at the time the structure was built.

How much money could you save by sealing your ductwork?


  • Are your upstairs rooms hotter or colder than your downstairs rooms?
  • Is your indoor air quality as clean and healthy as it could be?
  • Does indoor dust trigger your allergy and asthma symptoms?
  • Do your heating and cooling bills seem too high?

Aeroseal is a simple duct sealing process that has won national acclaim for its ability to improve and positively impact so many elements of indoor comfort, health and energy efficiency.  If you answered YES to any of the above questions, Aeroseal is for you!

Our comprehensive energy audits will evaluate your home and ductwork. Call us for your appointment today!

  • 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.
