Can a heat exchanger be replaced or repaired on a gas furnace?

I agree. Can it be done and does it make any sense
are two different things. The eqpt cost for a new high
efficiency furnace can be as little as $1000. And I would
think the labor of getting that heat exchanger out and a
new one back in could be the same or more than putting in
a new, drop-in replacement furnace.
