It all depends on total loading on each hot leg. There is nothing wrong with both A/Cs on the same hot leg as long as most other high current devices (water heater, microwave, converter, etc) are on the other hot leg. 30 amps is only 60% of the 50 amps available on each hot leg. If your breakers are correctly labeled you can determine the approximate loading of each hot leg and decide whether to move one A/C or leave it.
