Replacing AC compressor 98 Jimmy

The air conditioning on my girlfriend's Jimmy went out at the end of last summer. No big deal over the winter but now is the time to replace it. She had it checked out by a reputable shop last year and they told her it was the compressor. I'm looking to pick up a used one and swap out the faulty compressor. I've never delt with AC systems before, hell my ranger doesn't have AC. Can I (legally or physically) change the compressor and recharge the system or can I only change the compressor and take it to a shop to be recharged.

Specs on the Jimmy:

1998 GMC Jimmy 4x4
4.3L auto

after the replacement the system will need to be put under vacuum before charging so take it to a shop!! good luck with the repair!

Is there any refrigerant currently in the system? If so, take it to a shop and have them evacuate the system, then you can replace your compressor. Make sure to replace the O-ring seals on the lines in and out of the compressor, or you'll have leaks again.

Then take it back to a shop to have them recharge it.

As far as getting a used compressor, you're better off coughing up a little more $$$ and getting a new or "refurbished" one.

There is refridgerant in the system now. There aren't any leaks, just that the compressor is toast. Basically the best way to go about it is to get the parts and then take it to a shop?

most shops dont like it when you bring your own parts. They make money by marking them up to list. It would be like taking your own steak to a restaurant for them to cook for you.

You will need an A/C machine to pull out the refrigerant and vacuum and recharge to the proper amount.
