How many amps does an AC draw?

Most common voltage ratings for AC units are 115, 125 and 220 volts, and amperage rating can run from 15 to 20 amps. The lower two voltage ratings are common in smaller units, while units with a rating higher than 15,000 BTUs will require a 220-volt circuit.

What size breaker do I need for a mini split?

Use a 20A breaker and 12 AWG (or larger) wiring.
Because this is HVAC equipment, a 14 AWG circuit and 15A breaker is insufficiently sized. This is a continuous load, so you're only allowed to size to 80% of the rated ampacity, and the next larger size is 12 AWG and 20A.
