AC not working, blowing warm air

Hey everyone, wondering if you guys could help me diagnose so I know what to fix (or not to fix) for my 2009 honda civic. Been looking at youtube videos for possible causes, but theres only so much I can do without those fancy diagnostic tools.

Here are some of the things I looked at:

• AC clutch relay - a video told me its bad if it makes a sounds if I shake it, mine does not.
• AC fuse - looked at #19 and it still looks intact.
• Actuators - looked underneath the dash and it still moves without binding.
• AC compressor clutch - I noticed that it wasnt spinning when I have the AC on.
• AC condensor fan - does not spin when AC is on. Tried to get it to spin by tapping the motor + pushing the blade but it didnt spin. Electrical issue or whole unit needs replacement? Im not sure
• AC compressor unit - I don't know how to check if the whole unit is bad.
• freon level - I also don't know how to check if this is the cause of the problem.

What do you guys think? Worth fixing myself or take it to a garage? Thanks!
