Aeroseal Duct Sealing

Aeroseal Duct Sealing


Leaky ductwork is the #1 reason for home energy waste. Did you know that 20-30 percent of air flowing throughout your home may be getting lost through cracks and gaps in your home ductwork? All homes, new and old, have leaks in their ductwork and you may not know how much it is actually affecting your quality of living and your monthly energy costs. When your ductwork is leaking...

  • Energy is wasted.
  • The hot air that escapes from your ducts can cause moisture in your walls and damage to your home's structure.
  • Humidity, dust and dirt travel into and throughout your home through the air return in your duct system.


How do you know when your ductwork is leaking? Most of the time, your home ductwork is covered in gaps and spaces that allow air to leak out, and you can't even see it! 

Is your home subject to poor air quality and a lot of dust? Have you been noticing inconsistent temperatures throughout the rooms in your house? Are your energy bills high? 

If you've answered yes to these questions, your problems may be solved with our Aeroseal Duct Sealing technology: a scientifically-advanced duct sealing process that can save you money and reduce energy loss. 

Aeroseal is the first and only sealant that can seal your entire duct system. Unlike any other sealing process, Aeroseal attacks leaking ductwork from the inside out. When your ducts are Aeroseal-sealed, all of your ductwork is reached. The more common manual technique only seals leaks visible to the technician. With Aeroseal Duct Sealing, you'll see immediate energy savings while improving the performance of your AC and furnace by up to 40 percent. Aeroseal is so effective, the work is backed up with a 10-year guarantee. 


How can Aeroseal help you?


  • Comfort: Aeroseal stabilizes temperatures throughout your house and balances rooms that are too hot or cold.
  • Health: When you seal your ductwork with the Aeroseal technology, you reduce the risks of pollutants circulating through your home.
  • Safety: You'll reduce the risk of carbon monoxide and combustion gases entering your home through the ventilation system.
  • Savings: According to the Electric Power Research Institution, residential duct leakage can account for as much as 15 percent of a consumer's utility bill. Aeroseal Duct Sealing will increase your heating and cooling systems' efficiency by as much as 20 percent.
  • Environment: You will reduce air pollution and greenhouse gas emissions attributed to energy generation.


The Aeroseal Process


  1. Our technician will temporarily block supply registers and return grilles in your home with tape.
  2. A series of computerized tests are run to analyze air flow and your ductwork system so that you can see how much of your heating and cooling air is being lost.
  3. Once the testing has been completed, the technician will temporarily seal the supply registers again, this time with foam blocks and tape.
  4. The technician will then isolate your home's furnace, coil and IAQ products to prepare for your duct sealing.
  5. A flexible, plastic tube connects your ducts from an access hole to the Aeroseal fan.
  6. A fan blows Aeroseal sealant adhesive particles throughout your ductwork. Aeroseal particles fill in the holes and gaps, but will not coat the rest of your ductwork.
  7. After the technician has finished and your ductwork is sealed, you will receive a computerized analysis that shows the amount of leakage and total hole size of your ductwork before and after the process.
