According to the manufacturer's wishes - should last 1 day longer than the warranty. In reality - excluding ones with obvious factory defects who fail almost immediately (in first few months of use), commonly last about 10 years minimum, 20 years would be around the normal maximum I would expect with modern sealed bearings or sealed bushings.

In the "good old days" when they had oiling points instead of sealed bearings, probably about 3/4 of them would outlast the furnace if they were oiled annually - commonly about 30-40 years back then, but modern sealed bearings cannot be oiled even though they do use up the grease eventually, and they retain the wear particles in the lubricant so they wear out a lot faster than the older ones that caught the wear particles in a felt or sisal pad.

Generally, most should last as long as the furnace - which is commonly about 12-25 years these days before you hit the decision of getting a new one or doing major repairs like control board, blower motor, and heat exchanger.

You can google for Heil blower and purge motor problems - they appear to have a reputation for short motor life, and also some control board issues causing the motors to not work correctly even though the board is the real source of the problem - so be sure repair tech puts IN WRITING that the motor is warrantied for X time - commonly 1 year, sometimes up to 5 years with OEM replacements.
