How do I maintain the air conditioning system in my Ford S-Max?

I just got a Ford S-Max and I want to make sure the air conditioning system stays in good condition. What steps should I take to maintain it?

Regularly check and change the air filter to ensure that clean air is flowing through the system.

Get the air conditioning system serviced every year to check for any potential issues or leaks.

Avoid using the air conditioning system when the car is stationary to prevent unnecessary strain on the system.
