How do you recharge ref compressor?

To recharge a refrigerant compressor, first, ensure the system is off and safely depressurize it. Connect a refrigerant gauge set to the service ports, starting with the low-pressure side. Add the appropriate refrigerant while monitoring the pressure readings, ensuring they align with the manufacturer's specifications. After reaching the correct level, check for leaks and ensure the system operates efficiently before sealing everything back up.
