Lilima - I'm not in the heatwave zone. This is a normal summer for us There is no reason I believe that they'd be hard to get over here at the moment. Ceiling fans aren't an option being in a rental.

PacRakMG - I think you're talking about air coolers. Definitely more than $100-130. Looking at paying around $500. Possibly a little more depending on what size they do.

I had a split system in the last house, it was awesome. I haven't got that kind of money, or I'd be getting one installed for sure! I'm only worried about cooling down the living area's & hoping I can get one big enough to do the lounge/dining/kitchen area. Bedrooms don't bother me. If not, I'll block off the kitchen/dining area, or the loungeroom & just have one cool room.

That's what I did think MD, but having never used one & not knowing anyone who has, I have no idea. And since the frame is already there for a window/wall one, I may as well use it.
