One wire wrong on a capacitor, and the fan won't shut off, even pros mess up, it took me 40 years to learn this trade. you think I can fix your ac in 100 words, no. I offer advice like make sure the condenser is clean and the fins not folded and check that you don't use adapters on the cord. I'm not going to risk having someone that can't even LOOK at the condenser coil and see that it's stopped up, or tell to change a capacitor when I don't even know if they make sure there's no power to the unit, I would rather just be quiet but that didn't really work either. be safe, check the powers off, go as far as you feel safe, then call a expert. offer him water, have a good ladder and offer to help
