My old house actually had a cold room. The owners had the basement fully converted into a huge 4th bedroom that they intended to use as their master bedroom when they lived there, but it was always 10 degrees cooler than upstairs so they didn't even use it. I snatched it up immediately when my buddies and I moved in. They set the actual house in the low 70s so my room was always 65 or below =D. Sadly, the house I'm in now doesn't even have central air. I thought I was going to die this summer. I don't deal well with 80 degrees, let alone 100+.
