Is anyone senstive to A/C? Is it because of mold? I can't figure out if it's stuff in the ducts or just the air, because I don't like air blowing on me or the drastic change from the outside air. And then I'm wondering if it's dirty ducts or just chemicals in the air because I'm not bothered that much at home, just in commercial buildings. So I don't know if it's all the chemicals from all the people in the commercial buildings or the stuff in the ducts because it's doubtful they've been cleaned.
