I know someone who has a portable one that has a hose that goes out the window.He said it works fine but in this kind of weather where it's 93 degrees and high humidity,you have to be close to the unit to really feel the air.He says it has problems circulating but I was over at his house yesterday and I thought his place was rather comfortable.He paid about $400 for it (I think it's an LG)He has no regrets but thinks if he had to do it over again he'd get a window AC. We had this discussion because two summers ago I had trouble with my AC and the repair guy fixed the problem temporarily but said I'd need a new AC (which is gonna cost me around $4,000-$5,000) So, two + years later and it is still holding up fine and I'm hoping it lasts me this summer. If not, I may have to look at buying a portable AC myself.
