Our central air on the first floor stopped working last year but after getting prices to upgrade the system I decided I needed one which I can put in the window for now. The challenged was the window was a small slider and the rooms connnected including the kitchen so a powerful cooling unit was needed. Because of the size limits of the units available my expectations were low but this Figidaire unit did a great job keeping things cool this summer. Fridigaire has been a household name since I was a kid. Stick with a name you can trust and you can't go wrong
