Standing in front of the sink last night, I felt a cool breeze on my feet. I got down on the floor and started hunting for the source. I pulled the stove out and sealed a hole in the floor when the electrical runs thru. That wasn't it. Then I pulled the grate on the heat vent. Yup. Shoddy job. they just cut thru the subfloor and oak floor, wedged thething up screwed it to the wood and that was it. SO, I got a can of latex foam and sealed it up. Then I went around to other vents in the house ands sealed some of them. Afterwards I n oticed that I still had some draft coming thru the duct work itself. What can I do about this? It's a gas furnace and I have cold air coming from it. I find it hard to believe that the wood stove is pulling that air thru. The house is anything but tight . I have been going aro[und sealing and insulating things as much as I can but it still has a very long way to go. once I get everything done, am I likely have an increased problem of air being pulled thru ?? I figure it's coming in from my garage since that's where the furnace is located.
