Ok, so here is the deal. Got the final inspection today for the HVAC in my dedicated HT in the basement. Despite getting initial approval from the regional buidling department when I presented my schematics AND passing my rough-in inspection - the inspector today said I did not have enough air return to pass inspection (and hence pass code).
I need to add 200 square inches of air exit to the room. Now of course - it being the final inspection, the room is done (by which I mean drywalled, painted, molding, carpet, etc.) So I am left with a dilema of how do I resolve this issue and pass code. If I had been told about this during construction it would have been no problem, just add some passive air vents with the appropriate number of bends out of the HT and problem solved.
So does anybody have any great ideas? The only one I have come up with so far is a adding 12X24 vent to the component closet doors (it is a pass through closet with access both in the HT and from the back). But this will introduce noise from outside in and allow sound from the HT to the outside. Not sure there is any option that will not do this.
Boy am I PO'd
