anybody know how to read trane model numbers ? i am trying to find out what tonnage this one is. model number is, BYC100G3ODA. Is that 7.5 tons ?
B = always a "B"
YC = Gas/Electric Package
100 = 100,000 BTUH (8.5 tons nominal)
G = Major Development Sequence (7th)
3 = 208-230/60/3
the rest of your model number does not add up to what the catalog that i have says...so your unit or my catalog may be older.

Im not a Trane guy but I would guess the 30 means 30k btu = 2.5 tons.
Thank you, jayguy. it is pretty old, 1987
