Question Need Armstrong furnace age
Armstrong
Model number: G7A100DC12-11
Serial: A25175KKA

House was built in late 50s. The only number I see in the SN is 75, but it didn't look that old.

Thanks for the help!

I believe the second K is 1989...and the manufacture age is, typically, within 2 to 3 years of the ANSI date.
Use the search function above for further info...

According to my reference the first K is the month (oct) and the 5 before the K would be 05-95-85-75 take your pick
