Heating Coils in AC Duct?
My general contractor told me that I could save money by using the AC ducts for my heating. Usually this is with a furnace that cooks the air and dries it out. He says that you can put hot water coils in the duct system instead of in radiators or baseboard and the air will not dry out the same way.
Is anyone familiar with this system? Does it really give you the best of both worlds?
