First and foremost you need to get this checked out right away by a certified HVAC tech because it may be a significant problem and maybe even indicate a real safety issue. That said, no HVAC tech or anyone could diagnose a problem like this without actually being there.
Things it could be is a problem with the blower motor or there is a part(s) within the furnace that after years of heating and cooling, expanding and contracting, have worn and build tension during the heating cycle that is released when the part(s) cool. A certified HVAC tech will be able to determine the source of the bang and repair it or help you determine if the furnace needs to be replaced, though if it is a young furnace I would imagine it could be fixed.
There is a good string here that discusses this issue: http://answers.yahoo.com/question/index?qid=20101214175504AAEXU2t.
To keep legal happy, let me just say that I am not an HVAC contractor, and you should never even look at your furnace without having a qualified, liability accepting HVAC contractor present. To keep sales happy, let me just say that you can find an HVAC contractor that's happy to take your money here: http://www.furnacecompare.com/perl/find_contractors.pl.
