hi guys, a few days ago my car overheated and the engine stalled as the radiator did not have enough water. anyway, I got it fixed but mysteriously my a/c, which had been working perfectly since then, stopped working and the mechanic told me that the compressor doesnt work anymore and it needs to be replaced. I think he himself did something to it so that I utilise his services again but I need advice on a good a/c repairman in Karachi and price range etc because right now I am clueless. Thanks!
