84, please be careful what you say, you may get yourself in trouble. You have only been on here for a year, I have been for close to 10 and have been reduced from a "member" to a "guest", I don't like it, but I deal with it because it is worth it to be able to see all of the funny pictures and stories on the WoS.
This forum is what it is, it used to be hosted on a private server somewhere in Canada and was fairly relaxed and laid back, but then it became too big to handle privately hence it needed corporate backing, and you don't bite the hand that feeds you, hence the mods have to protect the sponsors.
As far as Goodman goes many GMP furnace units have a cracked HX or popped rings, my aunt's included, but it isn't the machine's fault as i have a 50k BTU (2 burner) GMP that was used for many years and is now in storage since we tore down the house it was in and its HX is still just fine. My aunt's one (3 burner) died because she put a couch/sofa over the in-floor return air vent and suffocated it.
So IME it really is the installation not the brand that matters.
