Upgrade to 50 amp. Get a cord and an electrical box that supports 240 VAC and up to 6 relays plus a master on/off relay, wire the new cord to it so that you have two 120 vac bus bars working, put a 30 amp breaker on one side and wire that to your existing AC power distribution panel. That gives you your existing AC power setup with no changes. Put a 20 amp breaker on the other bus and wire that to your new AC unit.

A 50A service gives you 50A's on each line NOT 50A's total but 100A total. That's the reason for using 50A. Both sides of the 120 can use a 50A breaker and he doesn't have to worry about using the heater or microwave. So if he did go to the trouble of putting in 50A service he could balance his load better by rewiring the breaker panel - just a very little more work than changing to 50A service.
