York age

Older York furnace
Ser. # WO-030228

Any help would be much appreciated. Thanx in advance.

1969, 1989, or 2009. Well, okay, perhaps not 2009.

That helps. I’m guessing '69 due to the fact that the WH right beside it was '71. My cheat sheet says the 3rd letter indicates age for York. Do you have some different info that I could use to update mine?? Thanx again.

If two letters, use the first.
If three or four letters, use the third.

Thanks Russel, I didn’t have that in my notes for York.:slight_smile:
