Gas and Oil Home Heating Furnaces - Cold air return(revisited)

I have a 1200 sq ft main floor and a 1200 sq ft finished basement,the basement divided equally into 3 rooms and a bath,one being the utility room with furnace,w/h,w/d,deep freeze.The entryway is wide open with a short stair to the basement and a short stair to the main floor.This is actually a bi-level and the basement is only 3 ft in the ground.All 2x6 constuction to the concrete floor.
There is no cold air return inlets in the basement,there are 2 hot air outlets in each basement room.I do find its a little cooler on the lower level and am wondering if i should have a cold air return or two down there and if so would i put one in the ulility room or not.NG furnace.Door to the utility room is always open.

I would never suggest putting a return in the furnace room since you may pull in CO..

If your family room wall is next to the furnace, I would suggest you to put a return in that wall towards the floor so you can pull the cold air off of the floor in that room. it may not hurt to put one in for the bed room as well, and tap into the return duct work.

I put in a couple for a friend and it made a big diffrence, now the basement is warmer than upstairs.

When you put a cold air return down there by the furnace. Take and turn the furnace fan on and see if it will pull the doors closed down there on the lower level if they are just about closed. IF so Id take and cut the door bottoms off an 1" or 2" to let the cold air out of the rooms there when the furnace is on.;) ED
