Wall was cold this early morning after the attic cooled off overnight. Switching the breakers to turn off power to bedrooms was unsuccessful. The breakers labeled as bedrooms didn't turn them off, and I didn't want to flip breakers on the apartment where my brother lives.
My grandfather says some guy he knew built the return air system years back and built it out of wood, I believe it has gaps and cracks in it and is sucking air in from the wall from the attic. I'll look in the air return box with a flashlight and see what it looks like.
