Hello,
I am going to be getting a new furance soon. The companies I have had give me estimates are pretty close together. Two of the three companies told me I should have my 35 year old metal ductwork replaced with fiberglass panel ductwork. I am told this will keep the air hotter in the ductwork and save engery. Apparently 10-15% of the heat in the air will be lost if I keep my existing metal ductwork. The cost for replacement is not really large, but is it a good idea?
Thanks,
