Why does AC use so much electricity?
Inside the evaporator coil, the refrigerant evaporates and creates a gas that gets pumped back into the compressor, expelling heat outside and sending cool air flowing throughout your home. This complex system requires a lot of energy to run, and the cooler you keep your AC the more electricity it requires.
How is AC consumption calculated?
To get the energy consumption (kWh), simply multiply the appliance wattage (kW or W) by the number of hours you use. For example, if you are using a 300W air conditioner for 4 hours per day, then you are consuming about 1200Wh or 1.2kWh per day.
