Why is the air conditioner in my Nissan Leaf not working properly?

I've noticed that the air coming out of my Nissan Leaf's air conditioner is not as cold as it used to be. Could this be a sign of a bigger problem? Should I take it to the dealership to get it checked out?

It is possible that there could be a problem with your air conditioner. It is always a good idea to get it checked out by a professional, especially if you notice a decrease in performance.
