The below style was used with "York - division of Borg-Warner"

Note that while this example indicates the second letter represents the year of manufacture, if two letters are at the beginning, the year of manufacture can be either the first OR second letter. The same year chart applies regardless. One must use other data or visual clues to help determine the year.

i.e. The below style could indicate the unit was manufactured in 1982 according to the second letter "M" OR 1978 according to the first letter "H"
