kurt Posted January 19, 2010 Report Share Posted January 19, 2010 I screwed up a job. Furnace oversized to the point it blew out the secondary heat exchanger (Cat IV). Nothing seemed out of sorts when I was there, I did the usual stuff. Now I have a customer that's being nice, but he's definitely in "Why didn't I catch this?" phase of our discussion. I haven't decided what to do, although I know this is going to cost me. Well, not *what to do*, as much as *how much?". Of course, I'm now flogging myself for not recommending he obtain a Manual J on the furnaces, but it just didn't seem necessary (then). What do you folks do with furnace sizing?
