Question: how much energy does a 2 ton air conditioner use?
Answer: A 2-ton AC at this SEER rating is approximately 15 amps; 3-tons is 18 amps; 4-tons is 21 amps. Next, calculate the wattage consumed. A typical whole-home air conditioner uses a 240-volt power outlet. Multiply the amps by 240 watts, which equals 4,320 watts.
