Does My Home Need Duct Sealing?

Did you know that over 90 percent of existing buildings in North America have small holes or cracks in their air ducts—resulting in expensive conditioned air leaking through their ductwork? A few signs that your home could benefit from duct sealing include:

  • High energy bills
  • Frequently running HVAC system
  • Low air flow from room vents
  • Inconsistent temperatures between rooms

The Duct Sealing Process

When you call GAC Services for duct sealing in Maryland, our certified technicians will perform the following steps, which take as little as four hours to complete and will result in immediate savings and increased home comfort:


  • First, we’ll inspect your home for duct leaks by sealing your wall registers so that air can only escape through the holes or cracks in your ducts.
  • We’ll do a computer generated analysis of your original register flow to measure air leakage.
  • Next, we’ll inject Aeroseal’s UL tested and approved sealing material into your ducts.
  • Once administered, the Aeroseal particles will get carried by your air stream to all the leaks in your ducts, where they will adhere to the edges and seal them.
  • We’ll then complete our computer generated analysis to show you how much we’ve managed to reduce your air leakage. Our customers love seeing the immediate impact duct sealing will have on their energy bills and home comfort!

How Often Do I Need Duct Sealing?

Not only is duct sealing with Aeroseal an affordable way to increase your home comfort while decreasing your energy bills, but it’s also long lasting. You should only need to administer Aeroseal one time, but it’s guaranteed to last for up to 10 years in residential applications.
