It's funny (and sad too) how in some parts of the world, AC is frowned upon: I visited France and Spain, the two sides of the border by the Mediterranean had about the same temperatures, but AC was a rare oddity in France, while it was very common in Spain.

It seemed to be due to beliefs, as the locals said they were afraid of getting sick due to AC -- while I don't disagree improper maintenance can provide breeding grounds for a bunch of microbes, just do the scheduled maintenance and everything will be fine!
