You asked: Should car AC be on all the time?

Running the air conditioner during the winter will help prevent the car’s cooling system components from wasting away. This helps reduce the loss of refrigerant which occurs when the air conditioning unit is not used for extended periods of time.

Can I turn on AC without starting car?

If the engine isn’t running, then the belt isn’t turning. That means your air conditioner’s not actually on.
