I got a portable one with 10000 BTU's. It sells for $700 at Bed, Bath & Beyond but I purchased a Costco membership just so I could get it for $500 instead. When I stand in front of it, it is definitely blowing out cool air...but NOT cold air. Maybe it's because the only air conditioner I've ever had is in my car, so I expect cold air. But of course the car air conditioner has freon and maybe this thing doesn't.
All I know is that I paid $500 and my students are dancing in a freakin' sauna. The studio is NOT that big. But it's like I have to run it all night to make the room feel cold. And then once a class comes in and uses up all the cold air then the next class gets a warm or hot room with a little cool air being blown out of the corner from the air conditioner. Unless this thing starts blowing ice cold air like my car air conditioner, it's a $500 loss. How exactly are air conditioners supposed to make a room feel?
