DO NOT even go there. The refrigerant has to be exact as required. It has to measured. If you do not know where to install it then I am sure you Do Not have the proper equipment.
First off if it is low of refrigerant then it has a leak. It is illegal to add refrigerant to a A/C system without first repairing the leak. You have neither the tools nor the skill to repair the leak, and to add the correct amount of refrigerant. Take it to a professional shop with the proper equipment and knowledge to repair the system correctly.
Refrigerant pressures vary greatly with temperature, that is the fundamental principal that makes refrigeration and air conditioning posible. Your question is too vague for a better answer. I am an HVAC service tech, and learning to interpret refrigerant pressures takes time to learn. If someone tells you you can add freon to a certain pressure, they are wrong, it is a combination of pressures and temperatures that have to be used to determine proper charge of refrigerant.
R134A refrigerant has to be an exact measurement. Unless you have the proper equipment then it is advisable to have a certified repair shop service the unit for you.
There is a label under the hood with the capacity. Today's air conditioning has to be exact. That means you will have to know how much refrigerant is in the system. Otherwise you will not know how much to add. It is best to have this done by a qualified repair shop that has the proper equipment.
Air conditioning works by having the refrigerant undergo changes of state of the refrigerant between a liquid and a vapor, and also through heat exchanges, where heat is absorbed by the refrigerant, and is then exchanged to the ambient air both in the condenser and evaporator. In order for the heat absorbed by the refrigerant to be able to be exchanged to the ambient air, the temperature of the refrigerant must be significantly higher than that of the ambient air. Compressing the refrigerant into a high pressure vapor (which the compressor does) increases the heat of the refrigerant, as, when under high pressure, the molecules rub together more frequently, thus generating additional heat to the heat already absorbed by the refrigerant. This facilitates the heat transfer necessary for the proper performance of an air conditioning system.
Yes, Chevrolet or Chevy is a proper noun.
I'd recommend having it professionally done if you don't know what you're doing. If you feel confident, then you can purchase a refill (i'm assuming it's R134a!) canister that has a gauge on it. I do believe the can will provide the proper procedure to test the refrigerant level.
Any refrigeration supplier provided you have the proper federal certification.
Yes, Chevrolet is a the name of a specific company and its products.
Unless you have the proper equipment, skill, and knowledge to recover the refrigerant and to pressurize the system and install the proper amount of lubricant & refrigerant then you should seek out a professional. It is illegal to release refrigerant into the atmosphere and you will be fined heavily if caught.
