There are a few conditions that will cause the compressor not to click on. It's rare that a conpressor goes out if the system hasn't been cracked open during the life of the car. Is it possible? Always. But in my experience it's generally something else.
As someone stated: check the thermal switch. It's there to turn off the compressor in the event it gets too hot. If it doesn't work it breaks the connection.
Also check the clutch gap. I'm not familiar with 8th gen civic a/c clutches but generally there is a manufacturer specified air gap tolerance. If it's too large the electromagnet can't pull the clutch in to allow the pulley to power the compressor.
Once again I'm not 100% experienced with these cars but check the a/c relay also. Rule out the cheap stuff before replacing the expensive stuff on a whim.
Normally, I'd say go oem, but compressors are way spendy. My Miata had a leaking one and I replaced it with a rock auto aftermarket one three or four years ago and it's still running strong. The price difference was almost $300.
