I came in from out of town today and my house was 86 degrees. It was blowing air but it was not cold and the outside unit was not on at all. I checked the breakers and nothing wrong. I cut the breakers anyway to see if that would do anything and the results were backwards. Now the outside unit runs, but the inside unit will not blow air at all. What is the problem?

in high temps AC units undergo whats called thermal inversion. This is when it blows hot inside and cold outside. I do not believe there is a fix for this. Maybe it is not properly sized for you room? If your unit is too small, it may be working too hard and inverting.
The air being blown at the condensing unit isn't the air that blows inside. I seriously doubt what you said about it getting so cold. I believe that the wires to the capacitor were improperly installed, and your compressor isn't operating. Don't confuse the outdoor fan operation with compressor operation (they both share the same contactor as a switch). On the capacitor, the brown wire connects to fan, compressor attaches to "HERM" common attaches to the contactor. I didn't mention the colors of the common or compressor wires because they differ among manufacturers.
First check your coil behind the filter. If this coil iss clogged the unit will over heat and cause the compressor to shut down. It sounds as if either the evaporator coil (inside) or the condensor coil (outside) may be clogged. If the unit is icing up on the inner coil then that coil is clogged or low on freon. I would think it would be cloggged instead of freon problem. To clean this coil you can go to the hardware store and buy a can of coil cleaner and use it following the directions The outer coil you would have to remove a/c from sleeve and take the unit outside. Using a water house flush the condensor coil from the outside in to remove debris.. These coils should look like a brand new car radiator when you finished cleaning. Reinsert the a/c back into wall sleeve after letting the water evaporate from the unit as to not spill water through out the area. Good Luck
At 115°F it is very critical that the condenser on the outside unit is perfectly clean and the fan operating. Try to shield the outside unit from direct rays of the sun. At 115° you could be reaching what is called critical temperature for the refrigerant. Yes, have it checked by a qualified service technician.
