If you are looking for a powerful and quit air conditioner then mitsubishi is a best for it.With a heavy duty compressors with a awesome cooling.But aware that somewhere in the fine print the mitsubishi air conditioners is not designed to tolerate temperature above the 42 degrees.They cool very efficiently if you select the correct size of the room.Service support is little bit slower than others.The only thing I would like to dislike is the remote control. Overall mitsubishi is good in air conditioners.
