Duct on basement ceiling -- can it be moved?

We have an small, two-bedroom, one-storey-with-basement house built c. 1930 that was retrofitted with forced air heating and A/C. As a result, there is a large duct that runs the length of our basement ceiling, right down the middle. It is impossible to walk from one side of the basement to the other without ducking, as the ceiling height under the duct is about 5'6". Visitors regularly bang into it. We'd like to divide the basement -- which is essentially a bonus room right now -- in order to add bedrooms down there (growing family), and we'd also like to not have to dispense aspirin to everyone who visits. The duct would have to be moved to accommodate this. We don't know if this is possible.

A friend suggested we run the duct up through the old furnace chimney and into the (uninsulated) attic, but that seems like it would be really inefficient -- plus would we then have to heat the first floor from ceiling vents? Another person suggested moving the vent to the far side of the basement, but there are windows, so that won't work.

As I'm sure you can tell, I don't know a lot about HVAC (I'm not even positive I'm using the right terms) and I'd like to know if this is a task worth consulting a good HVAC tech on, or if it's better to cut our losses and move to a house with more bedrooms. We really like this location, however. Thoughts?

Duct work can always be moved but be careful not to add to much length and keep 90 degree fittings to a minimum as it adds to length and static pressure. Can't really see whats going on from here so it would be best to get quotes from a few local HVAC Contractors in your area

Ducts can be moved and they can be made shallower up to a point before to much friction impedes the airflow. Getting the bottom of the ducts up to 6'-8" is what you need unless you can place them against a wall.

Going up to the attic through an old flue probably isn't practical for the reason you stated and the flue probably isn't big enough.

An HVAC guy might see something obvious.

One last thing is a basement bedroom needs a second means of egress per code and common sense. This can be a door or an egress window.

Thanks. This helps -- I was wondering if calling in a tech was even worth it and it looks like it could be. And yeah, we know about the egress window -- we have one and would have to make another if we do two bedrooms. Thanks again.

cwaters--

I know this thread is a bit old now. I was very curious to see what (if any) findings you received when meeting with an HVAC professional. I have a very similar issue and would like to hear if it was possible to move them out of the way or any other solutions, before posting another thread myself.

Cheers~

As the OP only made these 2 posts in 2012, my guess is she/he is long gone.
