Summary: So far the AC seems very good, but I'll know better when I get some very warm temperatures. I'm using this in a home office. Quietness was an extremely important consideration in purchasing this unit. Its noise level is quite acceptable.
Pros: Cools the Whole Room, Energy Efficient, Quiet
Summary: It's a good air conditioner, and it isn't loud, but after reading in Consumer Reports that it was VERY quiet, I was a little disappointed. Also it is made in China. Sharp is a Japanese brand, and I had hoped it would have been built ANYWHERE but China. I have a Frigidaire room air conditioner I bought a few years ago, and it isn't as quiet as the Sharp, but the remote controls are almost identical in looks, and work both air conditioners perfectly.
Pros: Accurate Temperature Controls, Cools the Whole Room, Dehumidifier, Easy Window Installation, Energy Efficient, Even Air Distribution, Quiet
