STUFF WE SEE ON THE JOB
We see some amazing things on the job.
A dirty orifice caused a flame imbalance on this furnace, resulting in “sooting” in one of the heat exchanger chambers.
Can you see the door to the closet where the A/C air handler is located? Of course you have to move things out of the way to get in there, but when space is at a premium …. not a bad idea.
Not the right way to vent a condensing furnace, but have to hand it to the installer for being creative.
