What is Aeroseal Duct Sealing?

Aeroseal is a patented process in which we seal your ducts from the inside, using a special aerosol mixture that is pumped in through your vents it slowly closes any holes that might be present in your duct system.

The typical process takes about 5 hours and it consists of the following:

  • A pre check, where we tell you how much AC/Heat you are currently loosing.
  • The sealing process
  • Post check, where we show you how much of your AC/Heat we have given you back

We get it, when we first learned about this process it sounded like magic, well its science but magic just sounds better! regardless you might have some questions so we will do our best to address them!
