If the air handler isn't running at all then it's not the capacitor in the compressor outside. The capacitor just puts a charge to the compressor to get it turning. The air handler (in your attic) will run even if the compressor (outside unit) isn't running. There should be some type of breaker in your attic or maybe garage to the air handler. Check these first. But something had to casue them to trip. You may have a burned out fan in the air handler so unless you can diagnose and have the mechanical skills to replace what's broken, the best bet is to call an a/c man. If you live in or near Pinellas county let me knPM me. I have a friend who works on mine that is pretty awesome and resonable and I can give you his cell phone number.
I just replaced my capacitor and had to flip the dam break outside a dozen times before it decided to work! My capacitor was only $14.99 just had to find a supply house that sells to common people lol!
I also just had to replace the capacitor. The air handler was running, just the compressor outside wouldn't run. It would hum for a minute or so then go silent. Thought it was toast but have a buddy who does AC that came and checked it out and determined it was the capacitor.
