View Full Version : Deciphering First Company Product Date Code
11-08-2009, 09:59 PM
Does anyone know how to decipher the date from First Company Product Serial Numbers? The following is the SN from a First Company air handler: Y02602 FC825546 442139. If it helps, the MN is 30VDX-3HW which is no longer available. The condo that the air handler is installed in was built sometime back in 1996-98. Given this info, I'm wondering if the first three digits of the SN, namely 026, denote the 2nd week or 2nd month in 1996. Any help regarding this matter is appreciated.

If your condo was indeed built between 1996-98 then most likely it is not any older than that. Is this one of those units in the ceiling, probably above the shower? Some of us HVAC guys referr to those as "pancake" units. The model number looks like a 2.5 ton to me.
heres a link to their list of products.

Figured out the 2.5 ton rating based upon the model number. Realize that the air handler was probably manufactured somewhere around 1996-98. Just really wanted to know how to decipher D.O.M. from First Company SN for future reference. Will be talking to a First Company rep today, so hopefully I'll be able to post an answer for all to view.

According to tech support, determining the D.O.M. from the SN is as follows:
The first alpha character denotes the year and the second two digits denote the month. Using the alphabet from A-Z, A = 1994, B = 1995, C = 1996, ..... (the characters I, O, and Q are skipped). An example would be C05 = May, 1996
