Circuit breakers are there to protect the wiring and not the device using the electricity. If your wiring is 10 ga to the A/C, then it is ok. If the A/C wiring is 12 ga then stick with a 20 amp. There is a new (well relatively new) type of circuit breaker - arc fault circuit interrupter (AFCI). While considerably more expensive than a traditional circuit breaker, I think it is well worth the price. If you find a AFCI tripping, then there is probably a loose wire clamp or wire nut in the circuit.
