What kind of furnace is that? Armstrong?

[BaldLoonie]

That is correct Kevin. Very good!

Why did you suspect cracks and what led you to suspect......flame roll outs or what?

[BaldLoonie]

We went on a 2nd opinion. Another company found the cracks then tried to shove outrageously expensive equipment down the wife's throat.

That Armstrong has to be at least 20 years old? Was it a natural draft? and that was made back when HX's were still made to last

[BaldLoonie]

80% induced draft.

Got one of those in our downstairs. 23 yrs old original to the house. See enough of them to know if they're prone to cracking in more normal conditions?

I've came across a few bad HX in Armstrong units... by volume I would say 50% are cracked... i can think of one of which looked just like a major manufacturing error. Junk IMO.
