Dense Packed Ducts

Return ducts used floor/ceiling joist and balloon frame wall cavities for return air. Once the walls were insulated the furnace suffocated and pulled all return air from the basement. The worst case CAZ was -12.3pa causing the furnace to backdraft and the basement to reach 97ppm of CO.

Yes in my location in upstate NY this is a common practice. Even more common while dense packing tuck under garage ceilings. Be carefull and beware. That is why we do constant pre and post job inspections. Sometimes even with a great inspection these can be missed. Learn from someones else's mistakes and try not to make the same one.
