I have a customer who had a remodel where all of the attic vents around the perimeter were covered by stucco, and the dormers vents were removed when the roofing was done. The windows and doors are all new and tight. What effect does this have on the AC and the heating units? She has stated that the attic air feels moist and the house is stale. The bathroom fans have nowhere to easily vent, so at the moment they vent into the attic. Thoughts please!
