Seems there is no freon

Please comment how I should Address the issue ...

How do I know when the compressor is bad - when there is no Freon in the system?

We tried recharging the freon last year - but leaked out quickly. We were just trying the - it took years to leak, maybe it will last years. It did not.

As thei has the "Old" freon, should the old be fixed?

Should I consider replacing stuff and just convert the system to the 134 freon?

In general, the car is running well - so I'm of the mind set to keep it. Other required work includes speaker repair and timing change replacement.

Zero rust, and no oil leaks.

Thanks for the comments and suggestions.
