4100 sq ft SFR, $7 Mil. 1994 build, 2 story, kitchen on 1st floor
I’m trying to be as accurate with my narrative as possible but can just observe and report objectively what I saw if needed. When I was onsite, I could not make heads or tails of what I was looking at. I noticed at least two disconnected ducts and a grease-like substance dripping from the plenum with the visible dampers. I touched the wet looking area and it was dry greasy, like Cosmoline (whatever the coating was on my new machinist tools) but smelled like rodent nest (combo urine/crap), actually the whole attic smelled like that.
It was difficult to determine this exact location because the attic was a bit mazy but appeared to be over the kitchen area.
Do range hood plenums have dampers as pictured or is this something else? The only other venting appliance(s) near the kitchen was from the water heater and furnace in the garage behind the range hood. The kitchen and garage were back to back.
