I had my ac refilled last summer and it was not that expensive to have it done. Cost just over $100.00 however, it did leak out had it done a second time for no cost and it last longer. I still have a leak that I havn't been able to pin point just yet but hopefully will this summer. But all in all it really wasnt too expensive to have it done. My mother did hers last year as well and has had no problems at all.
