i at a service call and there was water under the the furnace and spreaded from there. so i first checked the the secondary eat exchanger and there was no sign of hole or nothin i checked the side of it and notin not a single drop. the blower compartment there was no sign of moisture at all. i am kickin myself on this one. i even checked the bricks that elevate it and no sign of moisture at all i was there for 4 hours and absolutely no sign of a single drop of water comin from the furnce so i left as is bcuz i would feel guilty if i changed a part or watever and not fix the problem.and the custumer said since he bought it which was a year ago it was always doin it only when furnace is on cooling and heating mode only. am i crazy plz help. oh and its a tri level house if that help. thanks!!!
