AC does not get cold

Hello, If there are no leaks, and the refrigerant is at the right level, the next thing to check is that the compressor is energized when you turn on the A/C. Make sure you hear it come on, see it come on, and notice the engine drops in RPM followed by immediate recovery to at/above idle. If it does not turn on, time to check your fuses and A/C compressor relay.
