Has anyone replace an old Suburban furnace
(12SE) with the one they sell now (16SEQ)? I'm wondering if the intake and exhaust ports on the shell will line up or if new one's will have to be cut. My thought is that I can get a repair kit of the 12SE and new motor (sounds like and airplane taking off right now) or but a new furnace
for more $$$. The thing with the new one's is that they are supposed to be quieter. Not sure how much. My current one is from 2001 and the heat exchangers are kinda rusty and perhaps it would be best to replace.
