SINGER AC date code

I do not seem to find dating for a SINGER AC unit. It was difficult to read but I think it is a model: ACR51040-10, serial: 370138. I’m guessing 2001 but won’t give this to client unless positive. Does anyone have an age chart that includes Singer? Thanks.

Singer HVAC has been gone for years, decades even, I doubt it’s a 2001.


Looks like Dom is right. That model ran from 1975- 1979.

Thanks. Wow, it really is a SINGER (see pic) and is still operating.


Funny I had one yesterday also and it worked like a charm.
