I've had air conditioning in my cars for as long as I can remember and have always left them on regardless of what the weather is doing outside.
I agree we need to use them often to keep in good condition. Recommended by A/C specialists to run regularly to lubricate the susceptible parts.

In the UK we benefit from use in winter for dehumidifying. In my experience it is the switching on and off that leads to the smell and bacteria build up.

The switching off, ahead of a stop.... in my experience having tried it, it takes at least 12 miles running to do so, in average conditions when there is any humidity in the air, not a good idea here in typical UK conditions.

I leave my A/C on all the time and NO smells at all. Tried other ways of running A/C in the past and always the musty smell starts to build up when the 'on and off' method is used.

Plus we have "climate control" after all, that uses the dehumidifying/drying function as much as temperature control, whatever the ambient temperature outside.
