Having trouble finding the age of this HVAC unit.

Thanks for any help in advance.

Looks like 21st week of 1986.

Thanks RR.

There were 3 units in a high rise loft. Here’s another image of a different unit. They are all are similar in condition, style, type. This image if we were to use a similar format as you did would put it at I think 2003. That just seems not to add up.

Also a county inspect sticker on all 3 from 1999?

Me no likey these ‘’ First Co.’’ HVAC systems

**First Company - **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, D = 1997, E = 1998, F = 1999 G = 2000, H = 2001, J = 2002, K = 2003, M = 2004, N = 2005, P = 2006, R = 2007 … (the characters I, O, and Q are skipped). An example would be C05 = 1996, May

Jay!
