+1 yeppers nail on the head there. Especially when u are dealing with natural gas too. Best way to do is drill a 3" hole and pipe it in by the furance and problem solved. That is with a older house too with the new houses they have already got a pile that is drilled in for. Fresh air return to the furance. But another one wont hurt
