Why does the AC in my Nissan Micra not blow cold air?

I've been having issues with my Nissan Micra's AC not blowing cold air. It's been getting pretty hot and uncomfortable in the car. Any suggestions on what could be causing this problem and how to fix it?

The most common reason for this issue is a refrigerant leak in your AC system. It's best to take your car to a mechanic who can diagnose and fix the leak. Additionally, they will need to recharge your AC system with the proper amount of refrigerant.
