Air conditioner power consumption and temperature setting

The sales rep that sold me AC told me that my AC unit will consume about 1400W when starting up, then 700W *constantly* regardless of temperature setting (e.g. 20C vs 25C). Is that true? I'm guessing not, but I'm not sure.

I would expect it to consume 700W _while running_, regardless of the thermostat setting. If it produces enough cooling to bring the room temperature below the thermostat setting, then it will turn off, and consume no power, until the temperature rises enough for it to re-start.

The higher you set the thermostat, the less cooling it will have to do, so it will run for a smaller percentage of the time, and so the average power consumption will be lower.

I am not sure of this, but I would expect higher power consumption on warmer days since more work has to be done on the gas. It will certainly use more power on average because the machine will run more hours to cool the house.

But what is the definition of "running"? If I turn the unit on (press ON on the remote control) and set it to Cooling mode, then a blue LED will light all the time. However, from time to time another orange LED will light for a while and during that time the outside fan runs, but I guess this has to do with freshening the air inside the room by bringing air from the outside, and doesn't have anything to do with cooling. Am I right?

By "running", I mean actually cooling - the compressor and fans are running.

I expect that the blue LED is just a "power on" indicator, and that the air conditioner is only producing cool air when the orange LED is on - that is, the orange LED indicates when the thing is actually running, and doing useful work.

quite true for a an 2KW thermal power one ...
