Outside ac unit drawing too many amps
How old is your condensing unit?  Your compressor may be getting close to it useful lifespan.  As internal wiring and parts become worn, the compressor will pull more amps over time until something eventually gives.  If it is still cooling and not tripping the breaker you should be ok.  But I would probably set a little cash back for that final day when the compressor fails.  Sometimes it is more feasible to replace the entire condensing unit in lieu of compressor replacement if the unit is an old one.
