I agree it sounds like a condensation problem. And that's bad because
I think that is an 80% unit and it should not be condensing out any
water. Condensing units are made for that and use stainless steel and
pvc where they have water. 80% units do not and condensation can
cause all sorts of problems with the unit as well as the flue.
Basically on an 80% unit all the water should leave as vapor out the
exhaust. I'd look for other signs of water in the unit as well as in
the flue. Theoretically a different speed inducer could change the
exhaust conditions and cause condensation problems. You probably
should have got the original guys back out there. With any problem
that happens shortly after some sort of service the first thing to
suspect is what ever was just "fixed".
