I believe so, Its a tool with 3 hoses that one hooks up to the a/c line one to the freeon bottle and one to the air compressor and have a couple of gauges on it. I've never really botherd to look but I know my dad has recharged a few a/c units with it so I figured that was the right tool. I've never messed with a/c systems before.

I'll try it out tomarrow and if it dosnt work maybe you can take a look and do work on sunday if you have time.
