Does my brother-in-law have a clue?

I've never heard that, until now.

Maybe you should ask him where he heard that and what facts he has to back it up. If it *was* an issue, then why is it not addressed in vehicles manufacturers instruction books??

Hmmm, To me it is plain BS!

If you don't start it in the first place it certainly will last longer.

I once took a weekend vacation in Canada with my wife's uncle, in order to save fuel he didn't want the air conditioner on. $%^&*# never again!

If you turn off the cold air but leave the fan on for 5 min before you shut off the engine will help keep moisture from fermenting that horrible smell that can build up in the evaporator. Won't make anything last longer, just eliminate the moose fart smell when restarting the air later.

Dear friend on contrary if unit works as it should as soon as you shut off motor any condense water will drain, if you leave fan on the air humidity goes back in to your cab and other places, however you should start the car and idle for short time before you put the air on and if is really hot put the fan on, open windows before engaging air/compressor, let air circulate for little while before you engage compressor. the most people specially females want instant cooling or heat they don't give poor motor not even start running.

Has anyone figured out how to wring out those R22 Cans to get the last precious drop of that expensive Al Gore endangered substance?
