dtontarski Posted August 17, 2009 Report Share Posted August 17, 2009 Can anyone help me out in determing the age of this Coleman AC unit and this Unitary Products Group Furnace? While trying to figure this out I saw an online posting that Coleman, UPG, and York became a division of Johnson Controls. Did this result in new serial number coding? Coleman AC Model Number: TCGD24S21S1A Serial Number: W0G7014455 UPG Furnace Model Number: GM8S080A12UH11C Serial Number: W0C7506134 NOTE: Both of these units appear to be brand new - thus the UPG/York and the Coleman look up information I found online don't seem to work. Thanks in advance for your help. Dave Tontarski Quote Link to comment Share on other sites More sharing options...
dtontarski Posted August 17, 2009 Author Report Share Posted August 17, 2009 In thinking about it some more - the Furnace is probably an '07 based on the Unitary Products system of the 3rd letter in the serial number indicating year built. I still can't figure out the Coleman AC? Any help? Quote Link to comment Share on other sites More sharing options...
