Our advanced Aeroseal commercial duct and air sealing technology will help you experience comfort, save some money on gas bills, and contribute to the protection of the environment
AEROSEAL COMMERCIAL DUCT SEALING partners with 1 Clean Air to bring award-winning duct sealing technology to commercial buildings in Canada.
Proven Technology Backed by a Trusted Team
ESCOs (Energy Service Companies) and contractors consistently rely on our comprehensive solutions to address airflow challenges.
Our experienced team has successfully executed commercial projects both domestically and internationally. Our cutting-edge technology has played a pivotal role in enhancing comfort and energy efficiency across various sectors, including hospitals, hotels, universities, municipal buildings, military facilities, and offices.
Originally developed in 1994 by Dr. Mark Modera at the Berkeley National Laboratory, Aeroseal’s technology has received support from the U.S. Department of Energy. We continue to advance our award-winning solutions based on extensive field experience.
Proven Duct Sealing Technology, Guaranteed Results
The Aeroseal system is the foundation of our comprehensive process. It was created by scientists at the Lawrence Berkeley National Laboratories, with partial funding from the DOE and EPA. With more than 20 years of use in the field, our technology has a safe solution for any building type.
Verifiable, Guaranteed Results
Reduce Energy Consumption & Cost
Duct sealing addresses multiple sources of energy waste. For example, by reducing leaks 15%, fan requirements drop by 40% or more. This saves thousands of dollars every month. Aeroseal increases HVAC fan efficiency and eliminates excess ventilation load to reduce energy costs. It is a verifiable and guaranteed way to offer energy savings with typical payback in three to five years
Improve Indoor Air Quality
Leaks in the return duct allow dust and other contaminants to be sucked into the duct system and spread throughout the facility. And exhaust fans can’t remove contaminated air from the building if there are leaks in the ventilation shaft.
Improve Building Ventilation
Leaky ductwork is the primary cause of ineffective building exhaust. In addition to causing problems with uneven and uncomfortable temperatures, this can lead to higher energy costs, and added maintenance costs
Meet Code & Spec
As duct leakage specifications get tighter and tighter, Aeroseal is specified
as a routine component of commercial projects. Our consistent results will take you from hoping to knowing that you’ll meet code requirements – the first time.
