Best to leave AC on all the time.....?

Having read numerous articles whether to switch AC on and off as and when needed - it seems leaving it on all the time is the best option - saving the o rings and such like 'drying' out thereby prolonging the life of the compressor and such.....?

I never, ever use the Auto climate control - not sure the point of it - just blasts air out in all the places I don't want it! - especially when starting up..... its difficult enough getting warm air into the cabin (as has been discussed in other threads)..... so I have found setting at 23 and leaving the AC on best for me to date. Having to set it at 23 or above is a nonsense though - my previous Toyota LC would warm up well enough from 18/19.... Rolling Eyes

Any thoughts?

I’ve always had AC on, if they’ve had it, in all vehicles that I’ve owned or driven - from driving in the snow, in the summer, in the desert to driving in tropics or sub-tropics, etc. Have not noticed any adverse effects.

That some manufacturers have crap “auto” settings is their fault and not the technology’s Thumbs Up I think part of the problem is where they put the cabin temperature sensor.

Comparing the D3 MY05 and the last three V70s (MY00, MY10, MY14) I’ve driven the Swedes know for sure how to make a good automatic setting.

Just put climate control on with your required temp setting - leave and forget.

Climate control works great just takes a while to bring the entire cabin to the required temp.

I live in an area where it gets down to -6 in winter and up to 45 in summer and my climate control sits on 19 all year around - the only changes I make is to change from fresh air to recirc occasionally when outside temps are at an extreme or stuck in traffic with lots of fumes outside.

Auto on all the time, it can be annoying at times, especially when you first get in and its damp outside and as the engine is cold it blows no air at all so the screen starts to mist up!

My wife has left the a/c on in every car she has ever owned going back the best part of 20 years

I just leave it on auto a/c all the time. To help demist if needed, I turn on the heated screens and press the max button, which directs it all at the screen too for a bit.

The AC will come on in auto only when needed to cool the car if hot so leaving on is probably the best

This. I had never had a heated screen before the D3 but having used it for a while I think it is one of the best convenience features of all time. On the Volvo it conflicts (at least used to) with a bunch of technology packs (pedestrian detectors, lane warnings, intelligent cruise control, etc.)

In any (every) other car - set 21 deg & left on auto.

Wish the same could be said of the 15 & 16 MY Disco's, where it seems to be necessary to revert to manually controlling the system to maintain a correct temp. (Obviously an improved "Design Intent")

Nick J: Re the AC only working when it needs to reduce the temperature, that's logical, but apparently the system always cools the air down, then re-heats it to the desired temp. Can't remember where I read that though.

Totally off is bad. Eco and Auto are both good for longevity.

Mine is usually on Auto for de-misting purposes but on a longer winter run I do nudge it into Eco mode. As already mentioned the system keeps itself lubricated in both Eco and Auto modes.

I've assumed that is when it's off and the LED isn't showing. I tend to leave mine on, if off the car mists up something rotten if switched off. I'd often leave the D3 in "off" but ended up not bothering with that as it wouldn't make any difference to fuel burn. Thumbs Up
