Dual AC a handicap when only 30amp is available?

Our 30' TH was just fine up to about 90 degrees but above that, it struggles with 1 13,500 ac. We installed a 2nd ac in the garage area along with a second 30 amp power inlet and the appropriate wiring. Now we can plug in two two 30 amp receptacles (if available) or 50 amp with appropriate adapter (50 to 2-30) or 1-30 and 1-20.
This setup gives us the most flexibility possible and I think I like it better than just having a 50 amp setup.
