Take it back to the dealer and have them fix it, could be a compressor froze up or a fan froze up. If you disconnect the compressor and turn it on and it trips the breaker the fan is probably
bad. If you disconnect the Fan and turn it on and it trips the breaker
it is you compressor.

You either have something wired wrong or you have a direct short in the system. Are you starting the A/C or the furnace? If it's the A/C, it could be a shorted compressor, capacitor, fan motor or it's wired wrong.

DO NOT install a 20 amp breaker, you can cause a fire. The breaker is rated for the WIRES, and unless you change out the wires, the 15 amp wires will overheat and can cause a fire.
Typically, A/C units need dedicated power, with nothing else on that circuit.
One step that you may try is a new 15 amp breaker. Once a breaker starts tripping, is starts tripping earlier....
You may wind up running a new circuit for the A/C, if you do, size it for the A/C.

You have too small a cord on it if it's heating up and then popping your breaker. The a/c has am amp rating on it's data tag, read it and then read the amp capacity of your breaker and the cord your using. If the a/c draws more than 80% of the rated amps for the cord and breaker then you need to find another way to power it up with a bigger cord and a bigger outlet. DO NOT just install a bigger breaker, it is sized for the wiring in your home and a bigger amp draw on that wiring could burn your house down.

It is entirely possible that a five minute test would not produce any noticeable amount of water. Turn off everything in the house that is using electricity and your 20 AMP service will be sufficient to run your AC.

A/c is drawing 20 amps and keeps tripping breaker after running


If the fan is running and the compressor is getting hot and tripping off you may have a failed capacitor.
