Aeroseal is the quickest and most effective method to test and seal ductwork and meet today’s stricter building code requirements.
With Aeroseal, you will pass the IECC 2021 duct leakage test every time!
Priority Energy GUARANTEES IT!
Chicago-area architects, builders and HVAC contractors have begun specifying Aeroseal duct sealing at the initial stage of their new construction projects and high-performance homes. The aerosol sealant seals seams and connections fast, usually within just a couple of hours, and is so effective it is guaranteed to pass the duct leakage test every time. The computerized process efficiently measures leakage, seals and tests at the same time. Never worry about meeting the code requirement.
Why do the EPA and the U.S. DOE recommend Aeroseal? Because properly sealed ducts are such an important component of indoor comfort, indoor air quality, energy efficiency and lower utility costs! Your home buyers/customers will thank you for the recommendation. Go to our Aeroseal Facts and Benefits page for additional benefits!
Aeroseal is UL 1381 certified and Low VOC approved, by prestigious standards bodies such as ANSI/BPI (Building Performance Institute), NGBS (National Green Building Standard) and FEMP (Federal Energy Management Program). In addition, Aeroseal is an approved duct testing method by the State of Illinois.
Seal and Verify in One Step

New construction homes with ductwork in unconditioned spaces, like the attic or basement, must pass a duct leakage test, under the IECC 2021 building code requirements. To save time and eliminate guess work, more and more contractors are choosing Priority Energy and Aeroseal to get the results they need FAST! Don’t let the tape and mastic duct sealing method slow down your production schedule. Priority Energy can Aeroseal most new construction homes in less than one day and with only a few days advance notice.
Meet Energy Star and Advanced Certification Requirements
Congratulations! ENERGY STAR rated homes and buildings are built and tested to outperform the typical American home in comfort, energy efficiency and durability. Aeroseal duct sealing is the only way to achieve the stricter leakage requirement. (Priority Energy’s certified HERS Raters can work with your builder or architect to achieve the energy efficiency requirements for ENERGY STAR certification.)
Seal and Save
Don’t be fooled into believing that bigger is better! Properly sealed ductwork and an accurately-sized HVAC system will provide far better year-round comfort and long term structural durability than a larger-than-needed, more expensive system. In fact, an HVAC system that is oversized can cause humidity problems and discomfort, and will be more expensive to operate. For maximum comfort and durability, have your HVAC system designed by our professional staff and use Aeroseal to seal in success. Priority Energy’s Mechanical Design services (MEP) can provide your Manual J,D and S reports to get your project started right!
