How Coleman Serial Numbers Work

Coleman HVAC is a brand marketed by Johnson Controls through their ICP group. Coleman positions itself as a reliable, value-oriented HVAC brand. Note: Coleman HVAC is different from Coleman outdoor/camping products (those are a Coleman Co. brand). Coleman HVAC units are manufactured in Johnson Controls facilities and share the York serial number encoding system. The York/Coleman format encodes decade (H/J/K/L), year digit, and month (01-12) in the first four characters of the serial number.
