Missing Furnace Vent Cap - NOTE TO SELF.
That's what I thought walking around this house. It had been inspected by a relo company, another home inspector pre-listing and then by me.
From way in the back yard I noticed an odd furnace vent. It looked like the cap was missing.
Looking at it with my binoculars it was clear - the cap was missing!
To me it seemed that two things were obvious:
1. It had been like this for a while as it was very rusty, even on the shingles.
2. Given that time without a cap, there would be issues with the furnace vent and possibly the furnace.
NOTE TO SELF, check the furnace under that vent!
Inside the attic, I found the vertical stack, but it was far away and dangerous to get to.
It did attach to a nicely-sloped vent leading a good distance toward the furnace.
NOTE TO SELF - that's a long vent. And it's been getting wet! Doesn't metal rust?
Approximately 10' from the furnace that sloped tubing transitions to a flat tube, which eventually connects to the furnace.
That transition joint is very rusty. And it has been dripping onto the insulation underneath.
NOTE TO SELF - yep, it's wet and rusty! If water is getting out, furnace exhaust gases are getting out too.
We know that there are problems with the vent.
Unknown if there are also problems with the furnace. But probably!
Interestingly, none of these things had been noted on the previous inspection reports, provided by the seller on the kitchen counter.
This all started with a missing vent cap on the furnace flue, and a NOTE TO SELF.
It probably helps that I have 20/10 distance vision, and 20X, image-stabilizing binoculars to follow that!
My recommendation: hire your own inspector and have your own inspection! You may or may not have to make a NOTE TO SELF...
