Just received this air conditioner and installed the unit in a snap. I replaced my very loud Lg unit with this one. The new one is very quiet. I do have to say that the air flow from the new one is far less than the old Lg, however the new Frigidaire cooled the two rooms with ease. The Frigidaire is designed to cool 350 square feet so be sure that you plan to buy more than one if you are cooling multiple zones. I would recommend using this unit for a large room or two smaller rooms with a common open area between the two rooms such as a open doorway.
