Hot as Hell

Yesterday my new air conditioner was delivered and installed. I still have no air conditioning. How can this be, you ask? It was installed and when it was plugged in there was no power. The receptacle had burned out. We bought a new receptacle and installed that but now we have minimal power. I think the circuit breaker burned out. We called the electrician and he will be here this afternoon. My house feels like a pizza oven. Now comes the puzzling thought. Did the old air conditioner blow the receptacle and fuse or did the bad circuit breaker turn off the air conditioner? I can live with first scenario, but the second would mean that I spent $900 needlessly.
