AC power draw temperature or fan speed?

[izzzyyd]

What draws the most theoretical power? A/C temperature or the fan speed? Assuming it’s A/C temp?

Which would be more efficient

Low A/C temp + low fan speed

Or

Higher A/C temp + higher fan speed?

Usually all my cars I’ve had I’ve cranked the AC to a low temp and kept fan speed at 1.

But I would assume the AC compressor turning on to keep a lower temp would draw way more power than the fan just spinning faster.

The compressor draws a lot more power than the fan.

I think you are grasping at straws. I just put mine on auto and let it sort it out. I'm sure efficiency is in the calculation. I also set mine at 76° to 78°F in summer. I'm usually dressed for warmer weather and it is quite comfortable when the ambient is 88° and the dew point is 68°.

Also I set it at 66° to 68° in winter.
