Do Modern Air Conditioners require to be run regularly ?
In the past Air Conditioners required to be run regularly out of season( say weekly for 5 minutes) to lubricate seals therefore prevent cracking & premature loss of gas.
I wondered whether there is a A/C expert out there who can confirm whether this is the case with the modern vehicle air conditioner.

Leaving the A/C on all the time would not deliver the best fuel consumption.

I dont think it gonan be that much more. Maybe a fraction of more fuel will be used. The AC using more fuel is the thing of the past. I did not notice any difference in the fiel consumption leaving it on Auto all the time.

The MB automatic climate control is actually quite efficient, the auto function only turns on the compressor as needed, not like back when they were on almost always. In the cold months you can just use Auto+EC mode to save fuel, this prevents the compressor from turning on, although you may need to turn off EC if you get fogging.

Carsy,
I note that ur driving a w204 C220. All modern MB's have a variable A/C compressor to help minimise fuel consumption while using the A/C.
You'd be quite surprised how little the A/C uses during normal driving, in many cases less than with the windows open and A/C off.
I've driven in a CLK350 down the M2 (you'll know if you're in sydney) at 100kph on cruise control. 30DegC day, black car, A/C set on auto at 20C. I had a star diagnosis pluged in while driving and I checked the A/C compressor usaged while driving, it was only using 28% capacity!.
Admitedly i had been driving for about 30mins already so the temp in the cabin had stabilised, but the point is that I would have been using more fuel with the windows down and the a/c off as well as being much less comfortable!
just set the desired temp and leave the A/C on. I even leave it on in winter, stops the windows misting too!

Usually as a general rule on winter or cold days when the a/c system is not in use, every time the window defrosts is on use the a/c compressor turns on automatically so the system is lubricated.
