That would seem to suggest that the 50A umbilical is split into two 120V panels, one 30A and the other 20A. Definitely an odd way to do it, as 50A service is normally split-phase, so each panel should be able to handle the full 50A---unless a 30A-50A dogbone is used. Maybe that's why they did it?

Again, thoroughly check the wiring to the 20A main breaker. If it's all 10AWG or larger from umbilical to breaker, it should be able to handle a 30A breaker.

If it's only 12AWG as suggested, one solution would be to move the 15A circuit the heater is using, to the 30A panel. It is unlikely you'd use both the heater and air conditioner simultaneously.
