How much it takes, or how much it has in the system at any given time? To know how much refrigerant goes into the system, there'll be a sticker from the manufacturer - usually on the section of the HVAC compartment which extends under the hood. If this is faded or absent, the owner's manual should tell you. If that's unavailable, there are online resources.
As for what's in your system at the moment, the only way to tell is to evacuate, recover, and weigh the refrigerant you have in your system.
Usually, on most cars, this means that the weather is cool or that there is insufficient refrigerant in the system. It can also be caused by a restriction in the AC system or high temperature or excessive amount of refrigerant in the system.
To add refrigerant to your home AC system, you should first turn off the system and locate the service valves on the unit. Then, connect a refrigerant charging hose to the low-pressure service valve. Slowly open the valve on the refrigerant canister and allow the refrigerant to flow into the system. Monitor the pressure gauge to ensure you do not overfill the system. Once the correct amount of refrigerant has been added, close the valve on the canister and disconnect the hose. Restart your AC system and check for proper cooling.
To put refrigerant in an AC system, you need to first locate the service valves on the unit. Then, connect a refrigerant charging hose to the low-pressure service valve. Open the valve on the refrigerant canister and slowly release the refrigerant into the system. Monitor the pressure gauges to ensure the correct amount of refrigerant is added. Close the valve and disconnect the hose once the system is properly charged.
To properly add refrigerant to an AC system, you need to first locate the low-pressure port on the system. Then, attach a refrigerant gauge and hose to the port. Start the AC system and slowly add refrigerant until the pressure reaches the recommended level. Be careful not to overfill the system.

To effectively replace AC refrigerant, follow these steps: 1. Turn off the AC unit and let it cool down. 2. Locate the refrigerant lines and valves. 3. Use a refrigerant recovery machine to remove the old refrigerant. 4. Connect a new refrigerant canister to the system and add the appropriate amount of refrigerant. 5. Check for leaks and ensure proper pressure levels. 6. Turn on the AC unit and test for proper cooling.

The refrigerant itself does.
For your home AC system, you should use a refrigerant that is environmentally friendly and energy efficient, such as R-410A. It is important to consult with a professional HVAC technician to determine the best refrigerant for your specific system.
It means that you have a refrigerant leak, and will eventually lose all of your refrigerant. Then your AC won't offer any sufficient cooling, and if you run your AC with an inadequate amount of refrigerant, you'll eventually destroy your AC system. So it means that, if you don't want this to happen, you need to get the leak located and fixed. The presence of air in the AC system indicates a likelihood of a leak (or the leak) being on the low pressure (vacuum) side.
To add refrigerant to your AC system, you will need to locate the service valves on the system, typically found near the compressor unit. Attach a refrigerant gauge and hose to the low-pressure service valve. Start the AC system and slowly add refrigerant until the pressure reaches the recommended level. Be sure to follow safety precautions and consult a professional if you are unsure.
