Count me as one of the doubters. With a ceiling fan you

I guess if you had one area of the house that happened to be

significantly colder, then it might get you somewhere, but that

isn't the typical case......

I think it might even work in reverse.

If there's no air movement, you may get some stratification or at least a gradient with the hot air up near the ceiling and the cool air down at the bottom where you're sitting or lying.

Mix that up with the house fan, and it should end up all the same temperature. It would be the average temperature, very likely considerably warmer than the temperature that formerly was at the lower levels where you are.
