I need to do something about this heat. I can't afford an inverter air right now. (I'm trying to save up for cremation for my dog because I think the end is near. Also for dental stuff for me). I saw the portable ones. My bedroom is small (measures 15 by 12 of my size nine feet..lol). I looked at portable air conditioner but my window is only 13 inches wide. Anyone know about the portable air conditioners?
