Turn on/off Air Conditioner?

One for the most bizarre lack of feature on the 3RX and 4RX.....why they lack this one button but bomb us full of other seldomly used buttons.
I'll add when I have the defogger on, the A/C goes on...ok fine...but when I turn it all off....the next time I turn on the fan on, the A/C is left on. I have to dig deep in the navi to turn it back off. Annoying.

Your AC compressor only comes on when needed when you have the AUTO set to on and the temp inside the car is higher than the temp you have set.
On my 4RX when I push the OFF button next to the AUTO button, it locks out the AC compressor and yet still allows fresh air and heated air to move through the system. The 4RX will do the best it can to cool and heat without the AC compressor. If you want to enable the compressor again you just hit the AUTO button next the the OFF button.
Seems simple to me, like past Lexus I have owned.

Am I right? Is this truly the only way to turn off the compressor without turning off the entire climate system? Just cannot be.

I tried this and the system does not understand me, despite going thru the voice command set up, repeating 10 sentences and repeating myself many many many times. I think this whole issue of voice command requires it's own post which I'll do.

I live in a dry climate. The RX wants to run the compressor all the time, even when the heater is on. I, too, turn it off. The only way I have found on both my previous '13 and now my '16 is to go through the nav system. Turning it back n is easy, you just tap the Auto button (even though auto will already be green). I turn it off anytime the outside air is at least a few degrees cooler than I want the inside. In the Sacramento area, humidity is not an issue.

I just tried voice command and it "kinda" worked. The way my voice command system is configured, I have to say a category first ("climate"), then "climate control off." But the visual confirmation message after that said "Fan off" rather than "AC off," so it wasn't exactly what we were looking for.

Asked another way, is there ANY way, other than going thru the menus, to quickly (or even merely just "quicker than the menus") turn off the compressor without turning off all the other stuff.

Turning the AC ON/OFF is quite the process to be taken in most Lexus vehicle. In my 2011 GS, I have to hit "climate" which turns on the navi screen then hit the "AC" and that will toggle it ON/FF. On my newer 2015 GS, I have to press the "Menu", go to climate, and then toggle AC on and off. Why don't they just have a separate button for AC is beyond me. It's not a big deal but certainly something they can improve.
Why do you want the AC off? Some of you may ask. Well, in the Spring and Fall, it gets warm enough inside the car but not enough to turn on the AC. I just use the fan and the air coming from outside is more comfortable than using AC.

Let the A/C compressor run all the time. That way it gets lubricated properly. Turning it off for long periods of time will allow the compressor to dry out and then starting it when it has not been operated for a long period of time is very hard on it. Most modern A/C compressors have a variable vane system instead of clutches. Just because the compress is "ON" does not mean that it is loading down the engine. It varies the vanes to adjust to the required cooling but is meanwhile receiving the proper lubrication.

No. I see that you are in PA also (I'm in Pittsburgh). There are many times, esp in the spring and fall, where you want fresh flowing air without the chill or without being heated.

If you have carista, you can change the setting to have AC off all the time but you have to go in to turn it on when you want AC. You can ask the dealer to turn it off the next time you get your car service there. Had to change the setting in my 14 ES also, hate it when the AC is always on when you don't need it.
