95% efficiency gas furnace.
It’s taking it’s air from the attic, and I don’t think the exhaust is right either.
Is it allowable to get its fresh air from the attic space?
I would think both these pVc pipes should be at the exterior.

Combustion air from an attic is acceptable if there is a supply of fresh air coming into the attic thru vents. However, the end of the pipe must be above the insulation layer and not have a screen on it (IRC 2407.11.6 and figure G2407.6.1(2).)
Obviously exhaust must go outside.
Thanks Greg. You can’t tell from the pic, but there is a screen at the intake.
I’ll put it in the report, thanx for the code reference!
Those pipes need insulation as well.
Why? I’ve never seen them insulated in the attic space before. Just curious
