Aeroseal Tech Inc.

At every step of the way, I was pleased with Victor and Aeroseal. Do the research, and if Aeroseal is right for your house, as it was for mine, you won't be disappointed. My three-story house (in Toronto) was built ca. 1910, and the ducts are not exposed, so to get access to them, I'd have to open up walls. Since I bought the house in 2006, it's been far chillier than I would like in the winter, even after I installed a new, high-efficiency furnace in 2011. I wish I'd found Aeroseal sooner! The difference is remarkable. So much more air comes out of each vent, and the house feels uniformly warmer.
