Kenmark Air and AeroSealTM
Save you Money on your Utility Bills

This patented Duct Repair Technology seals 70% to 90% of leaks using a
fast and cost-effective method
A typical house with ducts located in the attic or crawl space wastes about 20% of heating and cooling energy through duct leaks. These leaks, as well as those between duct joints and beyond bends and junctions can be sealed remotely by Kenmark Air using our NEW Aeroseal system.
Aeroseal duct diagnostics and sealing
Once leaks are sealed, conditioned air is delivered more effectively and your HVAC system can operate more efficiently.In addition, indoor comfort is increased because cooled or heated air is distributed more quickly and uniformly.
Kenmark Air is now proud to offer this exciting new technology that seals air leaks in heating and cooling duct systems from the inside. The cost of labor is often prohibitive when sealing duct leaks using conventional methods. Aeroseal's fully automated process greatly improves the cost-effectiveness of this energy- and money-saving retrofit. The Aeroseal system can be used to increase HVAC system efficiency in many commercial buildings as well.
Kenmark Air aeroseal duct repair technology Click the image to see it full-sized. How it works:
First, Kenmark Air's highly-trained technicians perform a rapid quality assessment of the condition of the duct system. If leaks are detected, the registers and coil/fan/furnace of your HVAC system are temporarily blocked and the Aeroseal system distributes small dry adhesive particles into pressurized ductwork. The suspended particles travel in the airflow toward the only place left to exit: CRACKS AND LEAKS. As the air stream turns sharply through leaks, the particles are flung against leak walls, allowing a seal to build up, sealing leaks as large as 5/8 inch across — without leaving excess deposits on duct surfaces. Air flow, duct pressure and particle size are optimally controlled by a powerful computer program throughout the process to maximize leak sealing.
The Aeroseal software enables us to print system analyses, diagnostic results and benefits documentation on the spot, so we can review them with the homeowner immediately.
