You need to run it every now and then to keep the pump lubricated so it doesn't seize, but more importantly, if left idle the system can build up some pretty nasty bugs that won't do you much good, so at least once a month it needs a good run.

If it auto air-con ( I don't know as you did not say) then I would leave it running all the time, just set a reasonable temperature. Also keep all your face level vents open to allow the zone temperature control to do its job. In all the time I've had auto air-con I've never "frozen" nor excessive fuel consumption as it only runs when needed.
If manual or auto air-con never let it blow directly onto your screen as any sudden temperature change outside can cause you to mist-up VERY quickly. With a manual aircon con this happened to me at 130kmh/80Mph in France and it is no fun I can tell you!

What Gazza means is, if it's climat control (where you can set a specific temperature) then just leave it on. It both heats and cools automatically.

Manual air con is basically a chiller, and as stated above should be used at least once a month. Aside from bugs there can be corrosion due to condensation if you don't - air con dries the air too.

As to not letting it blow on your screen - well the fact is that when you turn the air distribution to demist the air con automatically turns on - so you can't always avoid it. The steaming up phenomemon can occur when turning on air con on warm humid days - there is initial misting before it clears. I've never had this on the move personally, always when starting a journey.

I'm new to air-con too. Always said I didn't need it since the windows can go down if it's too warm anyway.
Got to admit though, it's been keeping me tootsies nice n cool recently, so no going back!
One more question though folks...How often does air-con need recharged & how can you tell if it's needed???
