Over simplifying. Balancing is a good idea. But before wiring in a 2nd A/C you need to look at how distribution is already done. If the existing A/C is on hot leg 1; and the water heater, microwave, converter, and that outlet used to operate the DW’s 1500 watt hair dryer are on hot leg 2, then hot leg 2 already far exceeds hot leg 1. Adding the 2nd A/C to hot leg 2 would compound the problem. In that case putting the 2nd A/C on hot leg 1 would make more sense. Or better, move some things from hot leg 2 to hot leg 1 before adding the 2nd A/C to hot leg 2.
Two A/Cs are 30 running amps or less. That is only 60% of the full 50 amps available for one leg if no other high current device is also connected to that hot leg.
Need to look at the big picture.
