    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.

    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?

    This is a good question. How many techs carry a snake camera? Are most techs just doing a visual inspection? How many are using combustion analyzers for a inspection?
    Also, what's the issue with Trane 90% furnaces? What section of the HX is having problems? Does it include American Standard?

    I do visual, camera, and a ca. It all depends on the situation. I don't pull blowers and pull apart coils unless I suspect a problem based on the previous methods.

    What type of camera do you use? What's your method?

    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.

    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.
