My wife and I have bought a house in Ohio and the door to the backyard is a wood frame french patio door. When it is cold outside the door that does not open sweats alot. The door that does open does not sweat at all. I do not feel any air coming from the frame of either door. What can I do to fix this problem.
Its the frame and the wood between the windows. There is a register in front of the center of the two doors. I belive that the air is blown toward the room and away from the doors. It is a forced air furnace.
