They then attach that clear plastic tube to the only vent open and put air into the system. In theory it should be air tight but no system is. The machine then calculates how much added air is needed to keep the pressure at a certain number and that is how they determine what your area of air loss is. They then inject the product into the system as a mist and it finds it's way to the holes. The tiny molecules attach to the sides of the holes and begin to fill it in until it seals it. It does not attach to anything else in your ducting except where there is a hole.

You can search Aeroseal and there are some vids out there on it. Pretty cool stuff, pun intended,,,,,,

Attached is the report from One Hour. I almost cannot wait for the summer Texas heat to see the real difference LOL

What was the cost?

The improvement is impressive.
My guess is you will see a significant improvement. For one thing if you were loosing that much air from the ducts you were also pulling in air from the outside. Just that alone will make a difference beside the better AC efficiency.





Last July I was in ND with outside temps +100F, I was running both my 13.5K AC's. The inside of the RV was +85F, pretty much unbearable.

Then in Nov, after fixing my duct work and replacing my AC's with 15K units I was in TX and outside temps approached 90F, it took one AC ~2 hours to bring the temp down to 75F. Some of this was new AC's and some was fixing the duct work.
