Age of York high efficiency furnace

Recommended Posts

I normally don't have much trouble figuring out the age of heating and cooling units, however I'm stumped on this York furnace, the serial # is EGJM364379. I'm guessing the furnace is less than five years old by the looks of it, but I'm not able to get that out of the serial number.

Thanks for the help.

I'd say a 2000 model.

Normally when a York starts with 4 letters, the third one indicates the year. York does not use I,O,Q and U in their serial numbers (or they didn't). The last year that the Technical Reference Guide shows for York is 1998, which is a "G". Following this order, "H" would be 1999 and since "I's" are not used, the next letter used for the year 2000 is a "J".
