Trying to determine age and size of a Stuart Warner A/C split system with electric resistance heating. They are older models. The home was built in 1973.


Air condenser: Model #0-30-CA, Serial # 2117713
Air Handler: Model # U12, Serial # 1016

I'm guessing the condenser unit is a 2.5 ton. Thanks

My Preston’s Guide does not list a Stewart-Warner with that model number.

Thanks Steve, it looks to be a very old system. I guess I’ll just state that fact and that the age could not be determined.
