Works great! I purchased a smaller unit and moved it to my daughters room. So immediately looked at Frigidaire. This unit is amazing, sometimes we have to turn it down...lol
The only trouble we had was figuring out the screws. The instructions need better illustration. (A bolt on picture helps) 1 you need to seperate the casing from the air conditioning unit (2 people). Then you mount the casing to the window opening. Then you mount support pieces to the air conditioner unit itself. Pay attention to the screws we separated them according to the list and still had trouble. It takes 2 people to lift and slide it into casing at window (heavy unit). All said and done it's in and WOW, what a great unit. Feels just like a cool breeze. Keeps our rooms comfortable!
