A/C on when climate control is in auto mode
I own ES350 2024. I live in northeast. Right now we have temperatures slightly above or below freezing. I noticed that every time I run climate control in auto mode it automatically turns A/C on. My question is- why does it do it? I do not ask to cool inside but rather hear it to 66F. I am turning A/C off manually every time. No fogging of windows was observed when A/C is off. Should I let auto run A/C or keep it off?

How cam you tell the AC is on, are you looking in the Navigation/menu screen?
I have the same concern, no reason to run AC compressor when you don't need it, why wear the system out?
My '99 Avalon AC ran fine for 25 years with only one single recharge and I hardly ever ran it over the winter. I think it lasted so long because I only used it when needed based on my needs not a computer algorithm.
I have tried the voice command to "TURN AC OFF" and it does respond that its turned off but I think it's turning the entire system off, not just the compressor.
