Irrespective of whether the problem is connected to lack of insulation,
almost ALL duct-work should be insulated (excepting that which is in an
interior wall). Doing so will at least save on energy bills.

If you can easily reach the duct-work in question, the cost of insulating it
should be only a few dollars and a couple hours of time. Duct-work
insulation can be had at the box stores.

Payback should be in the neighorhood of one or two months of reduced energy
bills.


Not if you want to heat the basement at least a little bit. You have
to add heat one way or another so do it the easiest method. The
basement does not have to be warm, but at least above freezing.
