Gallery of Common Duct Issues
This gallery below shows some issues and air leakage points we often encounter while sealing ductwork. Each of these leaks represents an energy loss point as well as a comfort and air quality concern. In some cases these involved minor manual repairs in conjunction with Aeroseal to ensure the tightest duct system possible.
In each of these situations these issues were hidden and nearly impossible to detect until we pinpointed and fixed them with Aeroseal. Don't continue to waste money and circulate dirty air throughout your building because of these leaks.
The Aeroseal sealant does not coat the inside of the ductwork. The sealant only seals where it exits a leak, much like fix-a-flat for a duct system. See image to the right.

Duct connections near the filter cabinet and air handler are often overlooked during initial taping. This situation creates large air leaks in crucial areas of the duct system where air pressure is the highest, near the air handler. Note: this is a commercial installation less than 5 years old.

Take-offs in flex duct systems are major leak points. Often these are weak connections that can be easily overlooked or hidden beneath duct insulation. Any air lost through this point is a complete waste of energy. Why heat/cool your attic, crawlspace or walls?
