Hi, I’m new here and to inspecting. I’m actually working on my practice inspections right now and just completed one on my own home.
Our furnace is located in the basement below grade in a closet with double bi-folding louvered doors. I noticed some insulated flex ducting squeezed through into the ceiling above the furnace that’s just open into the furnace closet, but couldn’t find where it was pulling from. I found it pulling from the attic near the soffit, but it’s just the end of the flex tube zip tied to the truss and the opening is angled down toward the loose fill fiberglass insulation. but it looks like they just dig a hole around in the insulation where the tube is located.
I’m assuming this is not correct, but I’m having difficulty finding anything to verify this. To me, It looks like this could be an issue because you have no idea if the air is restrained anywhere in between the furnace room and the attic, limiting the available combustion air supply. Also, where they dug a hole in the insulation (about 18-24" across from what I could tell) is directly above an upstairs bedroom. So that tells me that room is not going to be insulated as well making it too hot in the summer and too cold in the winter.
Am I correct in this being a problem, or am I missing something that makes this ok?
