To add refrigerant to a window AC unit, you will need to locate the service valve on the unit, connect a refrigerant charging hose to the valve, and slowly add the appropriate amount of refrigerant as specified by the manufacturer. It is recommended to consult a professional technician for this task to ensure proper handling and safety precautions.
To check the refrigerant level in your AC system, you will need a pressure gauge. Attach the gauge to the service valve on the AC unit and compare the reading to the manufacturer's recommended pressure levels. If the pressure is too low, it may indicate a refrigerant leak. If you are unsure how to do this, it is best to contact a professional HVAC technician for assistance.

It does not contain Freon. It contains R134a. There is no need to change the refrigerant. Any A/C service should be done by a qualified technician, with the proper tools and equipment. Please do not attempt any service or repair without the equipment and expertise necessary. Serious burns due to frostbite can occur through contact with the refrigerant.
The only way to know if Freon (refrigerant) is needed in an air conditioner is to use tools and gauges to measure the performance of the system. The amount of refrigerant needed is based on the design of the entire system including the size of the unit, length and size of the refrigerant lines, temperatures, and type of refrigerant. Refrigerant is not consumed. If refrigerant is needed then the system was either not charged correctly when installed or there is a leak. There could be many reasons a system is not cooling. The correct answer to the question is: A skilled service technician will determined that the system was low on refrigerant by using pressure gauges, thermometers and other tools. There not function a home owner can perform to see if refrigerant is needed.
