The compressor should be cycling between on and off

Although its not availablev in our US CX-5, whats the difference between your A/C and A/C Eco selection when you push the A/C button?

It’s just a low power mode that economises the use of the AC. It may however not keep the windscreen clear in extreme conditions like four wet passengers getting in the car on a wet day. In that case the screen clear button or full AC may need to be selected.

How do you mean? It will keep the car cool to a degree but it steps up automatically to full AC if the car is too hot. For the most part, mine sits in “ECO”.

My understanding of "Auto" mode is that the blower "assists" in temperature control. If the current temperature is 29 degrees, and setting is 24 degrees, the "Auto" mode automatically increases the blower speed. Once it nears 24 degrees, it lowers the blower speed.
In my current experience in "Eco" mode, it kinda takes longer time to reach the temperature setting unlike the "Non Eco" or normal mode.

My understanding for CX-5s normal A/C mode is the AC compressor is always running (only cutting off when the ambient temperature is below 32F to protect the system freezing up) but adjusting the air temperature with heated air from heater core and thiss the old fashioned way adjusting AC air temperature in American vehicles. On the other hand the A/C Eco mode has the capability of cycling the AC compressor on and off when the AC air temperature reached preset temperature hence saving the fuel, and thats why the Eco mode.
There was a thread here where the owner said it wasn't cooling/heating quickly enough. I advised them to turnoff eco mode and fixed the problem.

Not sure any cars have AC that doesn’t cycle. How do you regulate the pressure?
That’s my thinking as well. The eco mode buttons are a 90’s throwback imo. The cars I see now rely on interior temp sensors to tell the system what is needed. The compressor will run until the desired temp is reached then it will cycle off and on.

That should occur only when 'defrost' or 'floor plus defrost' are the options.
Depends on the sensors when it should change to outside mode

Got to hope so.
To control the temp by dumping cold all the time and moderating it with heat would be absurdly wasteful.

No, it will choose recirc normally just at first to either heat the car as quick as possible or cool it as quick as possible depending on the interior temperature. They sometimes “hang” a bit so it might be advisable to switch it off on the control panel and then press auto again.
If the display shows eco or AC, the system is on and the compressor will run.
When the incoming air hits the cooling radiator, it immediately condenses and excess water drips out of the drain. This way, even when the air is then heated, it is dehumidified which keeps the windows clear and reduces drowsiness. It might be wasteful but it is always on in auto.

If that is correct, I may NEVER use auto climate control again. If the windows fog or I get drowsy, I will deal with it. But running that compressor all the time is ridiculous. It may be the best way to implement the automatic system, but it is just one more reason to be dissatisfied with it and avoid it.
Those who are disappointed in their gas mileage might try keeping auto off, and see if that helps.

It’s quite widely known that the AC increases fuel consumption but in moderate weather it sets back and runs in the background. In really hot weather the compressor runs under full load. The beauty of climate control is that left to its own devices it can maintain a constant temperature and make the interior a more comfortable environment. For me, it’s worth any slight cost.
