You have it done by an ASE certified tech in an EPA certified shop which has the equipment necessary to recover, store, and recycle refrigerant. Releasing it into the atmosphere is prohibited by federal law.
This would be due to the fact that the system has a leak, it must be found and repaired then the system will need to be evacuated and recharged.......
You may have to replace the entire compressor. Either way, it'll involve disconnecting and dismounting the compressor, and you legally cannot do this on your own. It must be an ASE certified tech who does this, and the shop which does the work must be EPA certified and have approved equipment, as they must evacuate refrigerant out of the system and prevent its release into the air. When the air conditioning system is opened up like that, the receiver-drier (if it's a thermal expansion valve system) or accumulator (if it's a fixed orifice tube system) will also have to be replaced.
No, not unless you have the right tools and training to refill it properly. You must evacuate the system before you can refill it; that requires special machines. Contrary to popular belief you cannot back-fill the system using the compressor to evacuate it.
It involves evacuating the refrigerant out of the system, and you'll have to open up the system, which also means that the receiver-drier (on a Thermal Expansion Valve system) or accumulator (on a Fixed Orifice Tube system) will need to be replaced. Legally, you cannot do this on your own. An ASE certified tech in an EPA certified shop with the equipment to evacuate, store, and recycle refrigerant must do this in order to ensure both that it's done correctly and that refrigerant isn't released into the atmosphere.
For HFO-1234yf air conditioning systems, components that must be approved or certified include the refrigerant itself, the compressor, heat exchangers, and any hoses or seals that come into contact with the refrigerant. Additionally, the oil used in the system must be compatible with HFO-1234yf. These components must meet specific safety and performance standards to ensure safe operation and to minimize environmental impact. Compliance with regulatory standards, such as those from the SAE (Society of Automotive Engineers) and other relevant bodies, is also essential.
Do not add refrigerant. You must completely evacuate the system, then fill it _by_ _weight_ to prevent overcharging. Overcharging can cause leaks and/or compressor failure.
because the compressor must be running to circulate the refrigerant in the system

There is little the common person can do these days to fix an AC system in a car. With all the environmental regulations, the system must be hooked up to a recovery system, and recharged only by those who have the qualifications (and license sometimes) to do such kind of work.
In an HFO-1234yf air conditioning system, components such as compressors, heat exchangers, expansion devices, and hoses must be specifically approved or certified for use with this refrigerant. These components need to be compatible with HFO-1234yf's unique properties, including its flammability and pressure characteristics. Additionally, lubricants used in the system must also be compatible with HFO-1234yf to ensure optimal performance and prevent chemical reactions. It's crucial to adhere to manufacturers' guidelines and industry standards for safety and efficiency.
