There is a cold air vent on the second floor which, of course, is designed to "****" and return the cold air which settles around floor level, to the furnace for reheating.
The ducting passes through a room on the first floor in a place which is hard "box-in" and disguise.
Is it really necessary to force the cold air to the basement - it's going to follow nature and return there anyway. If so, could this ducting be removed?
I appreciate that this may cause a few drafts but in a large home, this could be tolerated.
Comments please. Thanks, Alan (Canada)
