Carrier furnace info

Hey guys, I was wondering if anyone could help me with determining the age and capacity of a carrier furnace and air conditioner. I’m starting to wonder if I wrote the nimbers down wrong, but here they are.

model No: 58g5075-ea
Serial No: 1891a00564
Series: 160

A/C Unit
Model No: 38tg018300
Serial No: 1891e50251

I did look in my resources, but couldn’t find them. Thanks in advance guys.


they both appear to be 1991 units, I think you have the furnace # wrong but the AC is deffinately a 1991 and the serial for the fiurnace also looks like a 1991.



I get May of 1991 from the Technical Reference Guide

Same date - and I’m guessing at 1.5 tons

Hope this helps :slight_smile:

Thanks, you guys are great! :smiley:

I think I need to update my resources.
