No offence but what kind of crap AC do they sell you over there ?
When i last went on holiday to south of spain in Marbella we were in a large apartment, it was 90 to 100f every day outside, yet the Air Con had no problem getting down the room to it's lowest setting of 14. In fact when we got there it was actually cold, and it needed turning off. There was one wall unit one end of the apartment and another at the other end of the apartment and it wasn't a problem
hmm..
Or are the window units all crappy ? Because i know they are cheaper.
