Like the humans that inhabit them, homes are complex organisms. They can even get sick; when stricken with leaky duct work, houses can suffer from symptoms including inefficient heating and cooling, excessive humidity and dust, and even buildups of mold and bacteria. The technicians at Aeroseal of Philadelphia fix these and other duct-related issues during maintenance and repair appointments. Using patented technologies, they measure leakage and seal openings with a polymer-based patching solution. Dubbed the Aeroseal Process, it's suitable for restoring duct work in both residential and commercial spaces.
