I can run both of mine on 30. They draw about 27-28 total. One is a 15 and the other 13.5.

Keep in mind a 30amp is really only rated for 25amps continuous. Drawing continuous 27-28 amps is a good way to burn out equipment. If you are lucky it just trips the circuit breaker.

You may or may not be able to get both units going but it's really a not a good idea.

Huh? What gets damaged drawing 27 amps? A breaker only has two positions, on or off. If it is on, the power being delivered will be 120 volts +/- 5 percent per NEC. If it is tripped to off, the power being delivered will be zero volts +/- an infinite percent (zero times anything is still zero). Where things get damaged is when voltage fluctuates high or low. The only possible damage would be if something gets harmed by the power suddenly cutting out due to a breaker tripping. Almost all appliances are built with that potential in mind so they aren't going to be damaged. The biggest threat would be if something got harmed because the appliance stopped working. Pets might overheat if the AC quits and the Chicken Fried Steak is going to be mighty greasy should the electric frying pan cut out in mid fry, but the skillet and the AC unit will almost assuredly continue to work once power is restored.
