Why do it?

Not only does a leaky duct system mean higher utility bills and uneven home temperatures, it can also cause poor air quality. Many duct systems are located in an unconditioned space, like an attic or crawlspace. Having a leaky system allows unfiltered air from these spaces to enter your home. A sealed duct system improves indoor air quality. It also helps your heating and cooling system run more efficiently, increasing its lifespan, and saving you even more money.
