A reasonable rule of thumb is 1 kW per ton of cooling capacity. A typical single family home might have a 3 ton central AC unit. This means it is consuming 3 kWh per hour of operation.
Residential AC units are available in sizes ranging from 1.5 to 5-ton.
1 ton of cooling capacity is equal to 12,000 BTU/hr.
If you're purchasing a new AC unit, look for the EER rating. This will help you determine the cost to operate the device.
Watts = Cooling capacity in BTU/hr ÷ EER
Convert watts to kilowatts (kW) by dividing by 1000.

Yes, it easily can double to quadruple your electric bill, especially this time of year in California. A typical central air conditioning unit will draw several kilowatts when running, which is about $0.20 to $0.50 per hour.
