2000 E320 EC always On, no cold air

Hello there,

My air-condition is not working.
EC is always ON and no cold air coming out. (only hot air)

I checked error code and diagnostics.
Could anybody decode these and let me know what to do next ?

I already checked Freon gas is empty and compressor is not turning on.

1: 127
2: 100
3: 129
4: 112
5: 111
6: 172
7: 0
8: 111
9: 27
10: 0.0

error code:

Looks like I have a leak somewhere. Need to check and replace the hose.
I sopped the local mechanic he confirmed low on Freon gas and compressor is not turning on. And he said I maybe need to replace the compressor, which I don't think so.
I guess I just need to replace the hose and recharge the Freon gas.

any advice? Don't wanna be ripped-off. : - )

one more thing to add. I recharged Freon gas last year. It has been only a year.
