We mainly heat with two electric heaters so the furnace only kicks on below around 25 degrees so we keep the stairs blocked when we know the furnace won't be turning on and unblocked when it does. One night we forgot to uncover it and there was a noticeable difference in the furnace efficiency. I thought it was broken until we realized the stair were covered, I opened the stairs up and the furnace almost immediately got hotter and quieter. It definitely makes a difference on our 3400RL.
