I have noticed that I deal with the same issues with air conditioning. It's difficult to get the temperature just right. Even though I have the AC on and it's over a 100 degrees outside, I tend to layer my clothes when I'm inside. It's a little frustrating because I'm constantly taking things on and off. There's one very strange symptom I experience... I almost always have the goosebumps. Unless I'm working out and exercising, they're almost always there. I tend to have horrible heat intolerance and thrive in the winter; it's easier for me to control my body temperature in the winter for some reason.
You probably already know these things, but I thought I would share the layering part.
