If it is an inverter type, which takes the outside air in and either cools or heats it and slows down without stopping, then it will be very cheap to run. For every kw of heat or cooling it is rated at, you will get about 3 times the amount. So, for example, a 1kw until will give up to 3kw of heating or cooling. That 1kw will cost about 13 cents an hour (ish) but will become more efficient as it slows down and will probably cost more like 10 cents and hour on average.
Obviously, the higher the power rating the more it will cost.

If it's not an inverter type then it will use the amount of power it is rated at, eg 3Kw will cost about 40 cents an hour to run.

We keep ours on at 24C in the summer for cooling and 21C in the winter for heating which seems to be the best for us.
This July has been extremely hot and humid (even more so than August it seemed) and we have use the aircon quite extensively especially at night. Our electricity bill shows an extra 14 euro for the month which is pretty good I reckon.

Remember that each aircon unit will cost that, not overall. We have ducted aircon so 3 rooms upstairs and 3 rooms upstairs are just using one unit each and we never have both on at the same time. Only problem with the ducted ones are that they cost more in the first place and, if anything goes wrong, will cost a lot to have circuit boards etc replaced.
Saying that, we've had ours in for over 8 years and, just cleaning the filters twice a year, and they have worked perfectly (touch wood) for that time.
(Now I've said that one of them is bound to go wrong soon).

If the room temperature is above 21°, which it certainly will be in this weather, then the aircon will be doing nothing other than pushing the air around the room. The effect of the fan will make it feel that it’s cooling you slightly, as it helps to evaporate sweat from your skin which makes you feel cooler.

In cooling mode, it will attempt to lower the temperature down to the target temperature of 21°. If it’s currently around 27° (What is expect at this time of year) then it will be working fairly hard to lower the temperature, so will be blowing out lots of refrigerated air.

I know this as the remote for my downstairs unit was AWOL when I bought my house so I could only switch the unit on/off via a button on the unit itself without the benefit of a remote to change temperature etc - and its set to be 24 all year round on that.

Also, just to add I have a humidity/temperature sensor under my master bed in the villa to be able to remotely keep track on these things (and remotely enable air con/dehumidifiers etc when in the UK). The summer indoor temps with all shutters down are about 29 at the mo - they peaked around 31 during July.
