A/c Longevity Question

[Satchel]

A friend said I should always turn off the A/C before turning off the car, as the life of the A/C system will be shortened if I leave it on during the process of starting the car.

Anyone have any thoughts on this?

Should I worry about turning off the A/C before I turn of the key?

thanks

Turning the ac off before you turn the car off atleast 5 mintues before if bareable is a good idea to keep mould build up from moisture collecting and growing on the condensor.

Having the a/c runnign at start ,i can;t see a problem with it as the engine is cold and so is the system which won;t start for a few second before cylcing off and on.
