Ac will not come on just keeps tripping breaker in main fuse box
Bad capacitors, contactor, fan motor, or compressor.
SOURCE: ac unit breaker trips off
First thing to do turn off the breaker in the electrical panel, then open up the AC outdoor unit, including the disconnect box, that should be mounted on the wall near the outdoor unit. Go thru and tighten all of the screws and wire nuts, look for burnt wires, while you are at it.
Turn on the breaker and try again, if it still trips, then we look deeper;
pull the control panel off the outdoor unit and look for the contactor, this is where the power coming into the outdoor unit hooks up to. There will be a set of contacts in the control, check it out and see if the points are badly burnt,
If all off the wire checking still has not helped, it will more than likely be a bad condensor fan motor or a compressor, the compressor is the big black thing in the bottom of the outdoor unit, making sure that all power is turned off, pull the plastic cover off of the side of the compressor, there will be 3 wires, make sure none of them are burnt and touching the metal, if they are, repair the wire and test.
Try this and if you need to know how to troubleshoot to see if it is the fan motor or the compressor, just contact me back.
If this has been helpful, please rate me.
Contact me if I can help you any more.
Sincerely,
Paul

Whats the amp breaker? Is this for the inside unit or the outside condenser? If the inside and gas heat you have a bad fan motor, If its an electric furnace , the same, but if its the outside unit, the fan could be going bad, locking up and the compressor still runs and pulls high ampsand tripps breaker or the compressor is just pulling too many amps due to plugged coils with dirt , grass or weeds blocking airflow.([email protected])

20 AMP Circuit, huh? More on this below.
The tech probably didn't put a hard start kit on, but if he did, I hope he added the resistor to the start capacitor, or you could have a problem in the future. He probably put a soft start on it, a 2 wire device which looks like a capacitor. But only you will know for sure (or he.). As for warranty, manufacturers don't care about soft or hard start kits. In fact, they like 'em, because they extend the life of the compressor, which keeps them from having to pay for a new one.
I would be concerned with a 20 AMP circuit for anything higher than 2 tons. Take a look at the nameplate rating on the side of the condensor and tell me how many Running Load Amps (RLA) this unit is supposed to pull.
Also need to know your line voltage at the condensor, with the unit running.

You need to start with a basic inspection in the outside unit. For the breaker to trip immediately like that indicates a dead short. With the breaker OFF look at the internal wiring between the contactor relay and the compressor. You are looking for signs that the insulation may have been chewed by a rodent, or a wire is off of a terminal and in contact where it shouldn't be. If the wiring looks good, terminals pass tug test etc. you may have a shorted capacitor. Make sure to check the wiring for the fan too. You can disconnect the com lead for the compressor and fan one at a time to isolate the defective component if needed. Work safe! turn the breaker on for the test, and off again before you put your hand or tools back in.

Sounds like you have a bad capacitor for your squirrel cage fan , now as for the a/c unit sounds like you have a direct short in compressor to ground or leg to leg , check all wiring to make sure that it is not grounding out or melted together.
Check all the easy things first. Check that all the settings on the thermostat are correct for AC. Does the AC unit run? If not check the electrical panel breakers to see if the AC unit breaker is tripped. If it is tripped, reset it. If it continues to trip, call are reputable service company. There are little or no items for "do-it-yourself" unless you have the training and equipment to service AC. Good luck.
