I have a split level home that I've recently purchased. There is no leak, plumbing, air ducts or anything like that in my attic and my hallway walls are sweating bad. Happening right @ the hottest time of day and it seems to be alot of heat escaping around my attic access in hallway. I have gable vents and soffit vents but none of the things on house that spin around(don't know what they are called). Do yall think that this is a ventilation problem or something else? Got 2 get it fixed!!
