My husband and I are remodeling our basement and we want to make better use of the venting. Currently, the vents (2) are at ceiling level on the same wall with 1 cold air return at floor level. What we want to do, if possible, is move one of the ceiling vents to floor level and reroute the other so it is at the back of the room, also at floor level. The current ductwork is 8" in diameter with a top rectangular vent? that fits into the floor/ceiling. If we change the ductwork to incorporate a skinnier piece to go in the walls, will this have any effect on airflow? Also, will the cold air return "suck" the hot air right back into the furnace if they are placed within close proximity to one another?

Thanks in advance,

Putting the heat runs at floor level is a good practice for a basement living space. This will keep the floor much warmer than having the vents at ceiling level. You can install what is called "wall stack" in the framing to get the heat down to the floor. It comes in 6" and 7" oval sizes, or 3 1/4" x 10" or 12". An 8" round pipe is equiv. to 3 1/4"x 12". There are fittings and register boots that you use to install the new heat runs. Everything you need is at the local hvac supply store. Go there and tell them what you want to do. They will get you the right stuff. Avoid Home Depot type stores for an hvac project. No offense to Home Depot, but you will have a hard time getting the right stuff there. Yes, any added ductwork will effect air flow a bit. You should be fine though. Avoid 90 deg. bends with the duct, and tape the seams. Also, avoid putting the return air vent within 6" of a supply if possible. It will still work if you can't, but not as well.
