Cold air return size and type

I have another post concerning this same system.

I was told I couldn't use my existing furnace ductwork for a new centarl heat and air system because the air would cause the ducts to sweat so I need to install new insulated ductwork. Is this true of the cold air return ductwork too or can I reuse the uninsulated duct I already have ?

Duct work

You dont say where all this duct work is . Attic , basement , crawlway? But If the hvac guy said he had to use insulated duct then I would say the cold air return has to be the same. Did you get 3 bids for this job if not I think you should do so. ED
