My home AC (central air) decided it wasn't going to work anymore.. Now, I am not a "Jack-of-all-trades" so I am a little lost on how to fix the problem. My Thermostat is kicking on, but the unit fails to do the same. It is an electric unit. All im asking right now, is can someone give me a checklist of the simple fixes just to get me started... I've already checked the breaker and seems fine. On the unit itself, there is two breakers; one was on, the other one seemed like it wasn't even hooked up to something..it was just sitting there wobbly-like ... (possible culprit?)

please help...
