I recently moved to a fairly hot/humid area and my bedroom has a built-in wall AC unit and a ceiling fan. Over the past few weeks I noticed that if I have the ceiling fan on I'm comfortable with running the AC 2-3 degrees F warmer than without the fan. In general would the electricity of running the overhead fan be worth the savings of the AC not needing to work as hard? Both appliances are almost brand new and so hopefully are fairly efficient, but I don't have exact specs on either one. I'm just curious if anyone here would happen to know if there is an obvious advantage of one to the other?
