I have been considering getting my ducts sealed for a while now and after replacing my old windows, furnace and water heater I decided to finally take the plunge. I called a few Aeroseal contractors listed on Homestars and settled with Aeroseal GTA after speaking with Joe. Joe and Tommy showed up on time, and placed tarps on the floors leading to my basement to keep my floors clean. Joe and Tommy spent the first hour removing the old metal foil tape I had used on my ducts many years ago in an attempt to seal my leaky ducts. As Joe and I talked, I discovered that he has electrical engineer experience, sheet metal work and general contracting experience. After plugging all my air registers and sealing off my A/C evaporator coil, Joe attached the collar to my air duct and to his equipment to dispense the sealant. Immediately after Joe started his machine, the basement was filled with a fog of sealant leaking from all the leaks in my duct work. According to his computer I had about 376 CFM equal to a 71 inch square hole at the start of the process to just only 3 CFM at the end of the process!
The airflow from my air registers have definitely increased and there is an even distribution of cool air from my A/C. I will rest assured this winter knowing that the money I spend on heating will be more efficiently distributed in my home.
I believe that the investment in Aerosealing my air ducts will result in lower heating and cooling bills, a more comfortable home and reduced carbon footprint by using less energy. I highly recommend Joe and Aeroseal GTA.
