A:Answer This unit would definately work for the size of your window, and as far as the btu rating a 5000 btu unit will usually work for bedrooms up to 10x15 or so. Other factors to consider would be if you have multiple large windows or if you have high celings. If you have any further questions regarding choosing the correct size unit, you can always call 800-Frigidaire and they will be able to help you choose the correct unit.
