Duct leaks can be difficult and costly to find with duct work hidden between the walls, floors, and ceilings of any residential home or commercial building.

The older, traditional use of mastic or taping of leaks not only is less effective than Aeroseal, but also can be very labor-intensive and expensive and can only be applied to ducts with physical access.

Does your home:

  • have hot or cold spots?
  • have excessive dust/allergies?
  • have high utility bills?

Are leaking ducts costing you more than you think?​

Your ducts shouldn't cost you money, but they do!

About 47% of the average home’s utility bill is spent on heating and air conditioning. On average, 30 cents of every $1.00 spent on heating and cooling a home disappears through leaky ducts.
