To determine how much it will cost to run an appliance, find the wattage of the appliance, and multiply by the cost per kilowatt you are charged, then divide by 1000. This will be the hourly cost.

It will depend on how long the AC runs during any given hour. If you can estimate the percentage of the hour the AC runs, and look on the nameplate for its power requirement, you can estimate the cost by using the power cost per kilowatt hour.

To help you, rated volts times rated current gives you watts. Multiply the wattage by the estimated time it runs to get the watt hours. A kilowatt is a thousand watts. If your electric bill says a kilowatt hour (kWh) costs ten cents, 100 watt hours cost one cent.

First you will have to determine how much of the hour it runs. Then you will need to look at the units name plate outside and look at the FLA (full load amps). It will be running at 230VAC. Take the FLA multilply times 230 then what percentage of the time it runs. I.E. FLA=25amps, it is running 75% of the time. That would be 25x.75x230/1000=4.3125KW/hr. So if your electricity cost $.12 per KWhr that would be 4.3125x.12=$.52/hr

Phone your local power supply authority!!!!!
How can anyone answer this question when we don't even know where you are? What rates you are charged locally?
This is a silly question.
