Trane heat exchangers

[rchristie420]

almost every brand will crack eventually. thats crazy its only like 3 years old. i find a crack i a heat exchanger atleast once a day you got to know where to look, in those dimple welds, cracked eyelets, and right inside the burner tube is the most common. you do have to look and homeowners think your just trying to find something wrong with it. but they way i see it im trying to keep their house safe

here are some photos of a trane furnace I seen this summer when going a ac call. Furnace was only a few years old. The transition piece was not racked but the secondary had little cracks everywhere and of course would leak. Homeowners ended up doing new heat ex changer even thou I suggested a few furnace but I understand there issue I just wish trane would do something about this.......

Holy $*** that is the worst one I have seen. We have more issues with the primary than the secondary though.

looks like that one's been apart before.

The last one I had w/cracked header, only time filter was cleaned was when I went and condemned it- twice. She got new one after third header failed.
Wonder how many yrs before next failure?

well i have to say if homeowners had annual pm's done on there equipment a lot of these issue would be caught before they become like the photo's i had just posted.

chicagojonny, what do you mean by the button in the middle?

[chicagojohnny]

the way they are made on each chamber there is a round hole with a round quater size ring that is pressed on from expanding and cotracting it popped out causing a leak
