A wise guy would say "the difference is 2,000 btus" , but I'm not a wise guy. If you're looking at window units, the answer is "there's not really much difference". 12,000 btus equals one ton of cooling capacity and according to an old rule of thumb will cool approximately 400 to 600 square feet of area, depending on your geographical area, insulation, type of windows, air infiltration, etc. If you have a large area to cool and it's an older structure, you might want to consider using the mini-split sytems on the market today.
