How often should I run the air conditioning in my car?


This is a great question with an answer you might not expect. Ideally, you will run your air conditioning very often. You might think it’s appropriate to turn the AC system off in the winter, but that’s not a good idea and here’s why:

Discontinuing use of your AC system for long periods, e.g., during the winter, can lead to deterioration of seals and gaskets and, even more rapid refrigerant loss. What we recommend is that you run the AC regularly. On the coldest of days you can use the AC to ensure that the windows are demisted.
