I have a six year old furnace in the home I recently purchased. The original ducts and cold air returns are still in place. My question is, with the existing cold air return, there is a "jumper box" 12"x8"x64", jumping me over from two joist over to the next two, ending up with a grill in the floor of my main floor hall. This "jumper box" is huge and right in the way of my new hall to my family room in the basement. Could I do away with the "jumper box" and simply put grills in the basement ceiling, to provide the cold air required for my furnace?
Thanks,
Derrick
Answer:
If this is in the return air plenum, I would not dare do away with it and cold air will not willingly travel upward so you might check with a technician as to how you might circumnavigate it.
