I posted a picture of the trane primary h/x crack a while back. It is underneath the entry of the flame where the metal is crimped. I will find the thread and bring it up to the top of the forum. The secondary h/x are just about always cracked as well.

Dealt dct410. It's a 12v lithium ion. Has a spot for a micro sd card, and takes video and pics. The screen comes off so u can show the ho without carrying the whole thing around.

This outta be a hoot...

I don't really understand what you are asking. Whether it is a 80 or 90 I pull the blower housing and go from underneath on an 80 or check the secondary on a 90 for cleanliness or if it is a Bryant for corrosion. Also on 90% I remove the apex of the coil and put the camera in that way.

Is that what you meant?

We do the same, its a liability - being the last licensed technician to service the appliance it becomes our responsibility to ensure its running safely.

To be honest I used to not check "young" furnaces either. I seen a 6yr old Bryant secondary rotted last week. Now I check them all.

I would be willing to damn near bet a months pay that nearly every trane 90% trane ages 3-11 is cracked. there will be a class action lawsuit coming soon. the youngest one we have found was 13months old.

Now the real question.. How many of you will poke at the rust spots with your finger to see if it falls through?

If its that rusty I'm going to be just like a dentist

Yep every heat exchanger every call even if we're there to check the ac.

I always check heat exchanger for safety and replacement business. Doing. A good job pays in more then one way.

for sure a SAFETY issue!!!! Check it always.
