You can look for a label stuck to the radiator support. If it was converted properly someone should have stuck the label on there.

You can also look at the fittings on the A/C manifolds. Do a google search for images of 134a connectors.

Paying a shop to do a leak test before you've done some basic inspecting is a quick way to get into an expensive repair. Do a little research on the components, look around for leaking bright green oil on the A/C components (bright green flourescent dye to help ID leaks).

Do a little electrical troubleshooting to learn how to jumper your compressor and the aux fan. That way you can start figuring out if the individual components work before attacking the whole system.
