Once the Aeroseal air duct sealing is complete, the technician will again measure the duct system leakage. A sealing certificate and a tightness certification are generated by the computer. The sealing certificate shows duct leakage amounts before and after sealing, as well a graph of the sealing process, plus overall heating or cooling capacity improvement. The tightness certification, affixed to your duct system, shows the tightness of the duct system after completion of the sealing process. Aeroseal can reduce duct leakage by up to 90% and save a typical building up to 30% of HVAC energy use.

Duct Sealing Certification

When the sealing process is completed, the results are verified and provided to the customer. Click here to view a sample of the Aeroseal duct sealing certificate. While energy savings resulting from reducing air leakage can vary based on climate, electricity rates, and your heating and cooling system, the other goals of even temperatures in all rooms, improved indoor air quality, and reduction of odours and fumes will be achieved regardless of those conditions. In commercial building applications, Aeroseal also solves air flow and ventilation issues in addition to the energy savings.
