Unfortunately I don't have any pictures but I wanted to share. I was called out to a 8month old trane for a tune up. Furnace was installed by another company that was cheaper than our bid.

Furnace tripping high limit- gas pressure was set to 5.7
Flue pipe leaking water from every joint- never glued
Combustion air pipe was basically ran in the shape of a N creating a trap.
Inducer pipe not clamped
Heat exchanger cracked on 3of4 chambers
Humidifier wired straight to IFC and not To separate transformer. ( not sure if this is required but is a standard in our installs)

Client said the company has been back 6times in 8 months "fixing issues"
