How do I troubleshoot the AC system in my Kia Rio?

The AC in my Kia Rio seems to be blowing hot air instead of cold air, what could be the possible reasons and how can I fix it?

Check the AC compressor and make sure it is functioning properly. If not, it may need to be replaced.

Another possibility could be a leak in the AC system. Have a mechanic check for any leaks and repair them if necessary.

It could also be an issue with the AC refrigerant levels. Make sure they are at the correct levels as specified in your car's manual.
