Up here where I am AC is for rich people pretty much - in fact I feel like I have to regularly remind people from other countries that not EVERYONE in the States has it. We are more concerned with having a good heater for the nine month winters (did I mention it snowed yesterday?) So I've never had to deal with the AC being broken because I have never had it.

That said I find everything over about ~75 F to be unbearably hot so if I had money you can bet I'd invest in it.
