 to that comfort level, and then at nighttime when you go up to bed, you would condition your bedroom so that the whole house doesn't have to be 72 degrees or 68 or whatever it is you find it comfortable, just those spots that you're conditioning in. And if you get to that point in life like I am now where the kids are off to college and going somewhere else, then do we really need to keep their bedrooms the same temperature as everywhere else? And the answer would be no. I can condition where I'm living, but I don't have to under-condition or over-condition other spots that aren't being occupied.
