I needed a casement window cooler for a NON-casement window, and this fit the bill. I live on the 6th floor of an apartment that gets full sun 5+ hours every morning. I use this cooler in the largest area (dining and kitchen). It has been over 100 F every day the last week. I have been able to keep this cooler on the energy saver setting and still keep a nice temperature inside. I do have another cooler for my bedroom down the hall. Between the two, this new Fridgidaire is much better.
