Why - unless it is rusting. You would have to figure out (testing a day or so each with and without the A/C running) whether the cold is due to the cold slab and foundation cooling the basement (very common in houses where the basement is not tied into the HVAC system), or due to the cold ducts when the A/C is running. And if the latter, is it due to the cold ducts or leaks ?

If due to the ducts, just seam sealing and patching any holes in the ducts in the basement would take care of leaks - or if due to the overall cooling from the ducts running exposed in the basement you could wrap foil-faced fiberglass insulation around them.

Realize if you seal joints or insulate it will also mean a colder basement in the winter when the heat is one - and increased potential for mold/mildew due to decreased ventilation (if leaking) or due to prolonged cold conditions if colder in winter due to less radiated heat from the ducts.

Also - if this is an unfinished and unheated basement, insulating the ducts could result in the basement getting cold that pipes will freeze, so you have to consider that too.
