My mother-in-law recently was having some problems with her furnace and had a repairman to come in and take a look at it.

He looked at it and said it was beyond repair. The furnace has a leak at the point of connection where the PVC Exhaust pipe connects to the top of the furnace. The leak is excessive. It's causing the top of the furnace to rust and it is also shutting the furnace off intermitently.

The repairman blew air through the condensate pipe and that did not cure the problem.

What could be the problem? Why would the furnace leak at the point of connection?

Mike get a 2nd opinion before replacing. Your Mother-in-laws furnace is considered high AFUE condensing. It has 2 heat exchangers. The condensation is routed to a trap (sometimes mounted on either side of the furnce) then discharged thru plastic tubing to a condensate pump or may go directly to a floor drain etc. If the trap is clogged then this may explain why it's leaking at the PVC joint. Get out the original user / installation manual and see exactly how the tubing is supposed to be routed.
