Inspected a house the other day that had a Norge-Borg Warner gas furnace. This thing was as big as a Hum Vee but fired up OK and the blower worked fine but obviously not an efficient unit.
Model # GF1708 and Serial # CED-AIR. I question the serial # but that’s what was stamped on the metal plate. I would think that the furnace is 40 to 50 years old but the client wanted me to check and see if I could get something more accurate.
Any help appreciated.
