Assuming you are talking about a 96 or newer 134a system; There are two valves that enter the system. Both are on the metal lines coming off of the compressor. They are different sizes and covered with small black screw off caps. When you get a recharge kit it will only connect to the suction side valve (smaller of the two) which is where you charge the system.
To put freon in an AC unit, you need to first locate the service valve on the unit. Then, attach a charging hose to the valve and connect it to a freon tank. Open the valve on the tank to allow freon to flow into the AC unit. Be sure to follow safety guidelines and regulations when handling freon.
You have to add a valve to the dehumidifier in order to put Freon in a GE dehumidifier. The reason you have to add the valve is because dehumidifiers uses a sealed unit.
To put freon in a refrigerator, you need to locate the access valve on the compressor, attach a charging hose to the valve, and slowly add the freon into the system until it reaches the recommended level. It's important to follow safety guidelines and regulations when handling freon.
To put freon in an air conditioner, you need to locate the service valve on the unit, connect a charging hose to the valve, and slowly add the freon into the system while monitoring the pressure levels. It is important to follow safety guidelines and regulations when handling freon.
To put freon in an AC system, you need to first locate the service valves on the unit. Then, connect a hose from a freon tank to the low-pressure service valve. Open the valve on the tank to allow freon to flow into the system. Monitor the pressure gauge to ensure the correct amount of freon is added. Close the valve and disconnect the hose once the process is complete.
To put freon in a window air conditioner, you need to first locate the service valve on the unit. Then, connect a charging hose to the valve and slowly add the appropriate amount of freon. It's important to follow the manufacturer's instructions and safety guidelines when handling freon.
When you open the hood, on the left side there is a skinny pipe and you will see a valve with a green cap. This is where you put in the freon. When you buy the frion, it should come with a hose that just pushes on to the valve and shoots the freon into the pipe.
The freon has to be removed and the pressure released from the ac system. Then the valve can be removed and replaced. The system will need to have a vacuum pulled and freon put in again.

The schrader valve located within the low pressure side of the AC system.
Connect a freon gauge and freon can to the low side ac port. Start the engine and turn the ac on high. Open the valve to allow the freon to flow until the gauge reads full.
There is one valve that is used to add refrigrant. But you had better not add Freon. Freon is R12 and your vehicle's A/C system does not have Freon (R12) as a refrigrant. More than likely it uses R134a.
