I have tried this out in my master bedroom and it works great. It cools the room quickly and is pretty quiet. I have not tried it in the open living dining room combo but I will be grateful for this come hurricane season when I can hook it to the generator and keep my house cooler in these FL temps. It isn't as heavy as I thought it would be but it is not light either. Makes it nice to have my teens help me with it but I would be careful with younger children around.
