A/C not cold enough on 2009 Scion tC

I have a 2009 scion tc i noticed during on a hot humid day the airconditioner is not blowing enough cold air, its cooling but not cold enough. Is there a problem with the freon or it need to calibrate the thermostat? and what is cable adjustment for the a/c? thanks

There isn't any calibration to be carried out. A simple test is place a thermometer in the air conditioning ducts and see what actual temperature the air conditioning does cool to. Your car should be under warentee I would complain to Scion dealer and have them check the refrigerant pressures and temperature.
