I think it will work well to keep out the cold from the window air conditioner I have at work. However, I measured the air conditioner and ordered the appropriate size and it was too small. I did not return it because it fit a co-worker's unit. I have reordered a bigger size and hopefully it will fit and keep out the cold.
