This can should work fine if your system just needs a small charge to bring pressure back up...if it might needs more than 1 can then just buy the hose with gauge adn 1-2 cans of freon/134 to put in. really easy.
If you A/C system is not working at all or has leak, you might want to bring it to expert.
Hope this helped
