I have a split level house from the fifties, the master bedroom and one other bedroom site above the tv room(which use to be the garage). Above these rooms are the attic and where central air is piped from. While removing the base boards I had found a hole that went to the tv room vent, what was odd is the vent literally goes nowhere. I’m assuming this isn’t something to worried about but curious as to why it was done. Any thoughts?http://bit.ly/2F9dUNe via /r/DIY http://bit.ly/2RgNzn5
