Also someone mentioned the efficiency of an air conditioner, the efficiency of a modern air conditioner is 250+%. Meaning that the air conditioner is able to move 2.5 times heat energy from the cabin of the car to the outside, per unit of energy consumed by the compressor.

I really don't understand what this is supposed to mean or its significance. It is contrary to the laws of thermodynamics, and ignores all physics. You can't create more energy than is initially supplied. It honestly sounds like sales jargon from the box of an AC unit.
