The reinvestment/recovery act gives up to a $1500 tax credit (=$1500 extra you get back or less you pay) for qualifying improvements for the two year period from 2009 to the end of 2010. "Up to 30%" (can't find any sort of graded info anywhere, but it seems like you need 95% efficiency to qualify in a natural gas furnace.)
