speaking of red tags
3 weeks ago i did a maintenance on a furnace / Bryant model 16 years old beatin up / was reading 800 plus ppm at the exhaust ..  i know thos models are known for the secondary crack or clogged heat exchange ... indoor was only 6 ppm but stilll should be zero told the customer its really time for upgrade and its bad  and also told the  CX haven't really seen the crack but most likely it is gone bad and not worth the repair ,, so got them new furnace neXt DAY & every one was happy ,,,  what you think ? HIGH CO at exhaust still couldn't mean bad HE?

It was most likely a plugged secondary heat exchanger, don't cite a "cracked heat exchanger" if you didn't see one, and have no proof of a crack.  If the furnace is producing an exuberant amount of CO, I would shut it down as a hazardous condition, and not mention any crack, but the more likely scenario of a plugged secondary.  You can first try to flush the secondary out as outlined in the carrier service bulletin regarding plugged secondaries.

Never tag a furnace as cracked heat exchanger if you can't prove it,  this tactic is what gives our good service people a bad reputation and customers second guessing every we do.
