This is for serial numbers.

Lennox: Either the first two or second two digits are the year, it varies by era, but most of them actually have a separate sticker somewhere that has the year printed on it. Newer ones are first two equals manufacturing plant #, 2nd two are year and letter in fifth slot is month (A thru M minus I). So 5898G 07568 would be Plant # 58, Year of MFR would be 98 and month would be July.

I’ve learned not to use model numbers to determine age, although it can be done well in some circumstances. Model numbers, though, are like car models: the Mustang model has been made from 1964 to today, but that ol’ serial number will tell me everything I need to know about the date it was made.

Thanks! I have a HAVC person inspecting the furance.
