I am trying desperately to 'date' the furnace in our home. The home was built in the very early 1900's and has remnants of a coal chute, etc. The furnace in place now is an aqua colored Rheem and is outfitted with a Crown A-40 humidifier (disconnected) and a sticker on the backside stating it is capable of AC also. The Rheem # is 2432-130 , series #AF-AFO. It states it is 154,000 BTU built in New Castle, Delaware. I would love to figure out the age of this furnace for curiosities sake but also to update my home's system if need be. Anybody? Please? Thanks!
