Hi,
My AC contractor need a hole on the back side of wall to through a duct. My builder cut one for him. But builder did not use any lintel or anything else to support the weight from above. I asked my builder, he said it is not necessary to support above weight for this size of hole. is it right? I feel it is so strange nothing to support on the top end.
The hole is about 2 bricks wide( 460mm) on brick veneer. there is no any weight loading at the above position of the hole.
