Singer a.c.

I need to find out the age on a singer a.c.
The model number is BCE22004 1 9
Serial number P216
Can anyone help?

I think that S/N is wrong, but most Singers are from the 70’s, maybe early 80’s. Unless this is one of the ductless mini-splits, the Singer name was used on some of those.

Safe to say “beyond average lifespan”

I checked the plate, the s/n is correct. I marked it as beyond expected service life. Thanks anyway lads.
