Aeroseal GTA and their service was something I had stumbled upon due to a lingering need and frustration I had for years. We had a new multistage furnace installed recently and when it came time to use the A/C, I was pretty disappointed that we were experiencing the same issues; freezing basement and a sauna on the top floor.
I shot them a message and they were here within a week, they informed me I was loosing 309 CFM (the equivalent of a 59 square inch hole) within my walls and floors. After perform the service, the loss had drastically reduced to 7 CFM (the equivalent of a 1 square inch hole)!!!!! My cooling is now evenly distributed amongst all floors! Truly amazing and life changing.
If you are experiencing the same issues (freezing basement, etc) this is an investment you NEED to seriously consider.
Thank you to Joe, Tibo and Tommy.
