15 minutes could save you 15% more, on your heating bill

So I just went down to my friends basement to change the filter for his furnace...
Hmm, thats odd, only 2 of the 3 main ducts are connected...


...Wonder what his heating bill will improve too

yea i think my furnace in my crawlspace is like that to it does save money..my room is really warm to since the furnace kicks on a lot in winter and i live in michigan so it gets hot since im right on top of the furnace pretty much..
