The technician is recommending a new furnace based on the age and based on
the bulges and rust. Do I really need to be seriously thinking about
getting a new furnace at this time because of the rust and bulges, or is it
possible this furnace could last several more years? I believe they
recommended a new furnace 3 years ago when I moved in although I don't
recall anyone showing me the bulges before, but I'm suspecting they could
have been present 3 years ago too.

This technician is probably right. You should start planning for
a replacement furnace fairly soon. Yes, the existing furnace may
last a while longer. But it may fail as soon as the really cold
weather sets in and then you'll probably have a very hard time
finding anyone to work on it unless you're willing to pay a
premium price.

But you'd also be crazy to give the job to the first guy that
came along. It's time to get recommendations and prices from
several firms and think through exactly what kind of system
you're going to want.
