two different point of views, got to love how the internet brings these opinions together. To continue the Dodge Neon metaphor, that car had a high number of problems, but all in all, when taken in context with total percentage of vehicle sold, it was pretty much equal to most cars in its size. If a builder builds a whole subdivision and installs hundreds of those units, all the failures the techs will see will be related to those furnaces, hence, associating that brand with those problems. Is this a reasonable assumptions?
Regardless, nothing I can do now, but what TXV recommended, hope for the best and plan for a heat exchanger replacement in a few years. basically, what I would have probably put towards an upgraded furnace without a guarantee that the higher cost furnace wouldn't have had its heat exchanger fail as well.
