Q：Would this be enough to keep a room comfortable in summer without a/c?
A：I would have to say for me, it would have to be... No. I am a heavy dude and like my cool air in the summer. It does cool myself down quite a bit. I some times put it in the window to bring in the cool air at nite. It has worked real well for me. But I do use it in conjunction with the air conditioning. I enjoy my fan.
