Behind the Scenes of the Aeroseal Duct Sealing Process

- 11:28 am - June 17th, 2022

You may or may not already know about Aeroseal, and how duct sealing can help improve a household’s comfort and your family’s safety and health. And it’s true that you can save upwards of 20% on energy costs with properly sealed ducts.

Have you ever wondered how it’s done? Sometimes it’s good to know what will be happening in your own home when you schedule an Aeroseal Duct Sealing through E.T. Lawson. So with that in mind, we’re going to breakdown the process for you.

Here’s what you can expect on the day of your Aeroseal Duct Sealing:

  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 more before and after the process.

Seven steps, that’s all that stands between you and energy savings – and we could all use a little bit of that these days! Give us a call or contact us online to learn more about our Aeroseal Duct Sealing service.
