Yo!
I'm trying to find out the age of a Carrier RTU. Does anybody know the nomenclature of the serial numbers? I would have called my supply house but of course they were closed just 5 minutes before I got the number off the unit...
The serial # is 4394G30380. I guessin' that this machine is from 1994? Just a guess tho...
Thanks for any help!
