House was built in 1968
“Radiant-Aire” brand forced air gas furnace
MN: Q-120-80
SN: 23400
It looked old enough to be original, but just checking.
Any help would be appreciated!
Very often on those old furnaces the date is on the Fan cage
I think the term “Beyond service life” applies here!
I can’t go back and look at it again.
Thanks Roy
