A typical 12,000 BTU air conditioner, which is commonly used in residential settings, may consume anywhere from 1,000 to 1,500 watts of electricity per hour when running. To calculate the daily or monthly electricity use, you would need to multiply this by the number of hours the air conditioner is in operation.
