I live with two guys in a 2 bedroom duplex, my room is in the basement....its not finished but we laid carpet and build a bar and its pretty tight other than the concreat walls and no celing....oh and no heat...it is now december and its not going to get any warmer...I am wondering...since the vents aren't covered...can you ad a vent to one so I can get some heat pumped down here or would that mess some things up?
