FWIW, don't count on saving any money over the life of the furnace though. High-efficiency furnaces break down a lot as they age.
Any fuel savings you accrue today will be eaten up with expensive repairs after the furnace is 10 years old or so.

My furnace came with 10 year P&L warranty plus heat exchanger is on life
time warranty.
