Adding refrigerant to a compressor is a precise job to take on, and it is important to know exactly what you are doing. Attaching the Freon kit, turn on the compressor, and adding the refrigerant are the steps to adding refrigerant to a compressor.
An A/C shop will know. The leak must be repaired before adding refrigerant.
If you are having to add refrigerant, then this means you have a leak, and you will be adding refrigerant again in a few months. It is illegal to add refrigerant to a system with a leak without first repairing the leak. So, my advice is to take it to a professional and have the leak repaired and refrigerant added with the proper equipment, which you do not have.
R134a refrigerant pressure should be around 28-32 psig with good airflow across condenser(radiator)coil and engine rpm at or around 1500
the nitrogen is only used to clean out the lines prior to adding the refrigerant
Recharging a window AC unit with refrigerant involves locating the service valve, connecting a refrigerant canister, and slowly adding refrigerant until the correct pressure is reached. It is important to follow the manufacturer's instructions and safety guidelines to prevent damage to the unit.
The factory installed OEM refrigerant was R12 Freon. As Freon is extremely expensive and no longer in production, I suggest you have this vehicle converted to R134a. Seek help from a professional for the conversion and repair of the leak you must have or you wouldn't be adding refrigerant. You will be money ahead rather than just adding R12 to a leaking system which BTW is illegal.
By the amounts of F**ks i give
Check with a local hvac contractor for an estimate.
Generally you charge a refrigeration system by weight, not by pressure or temperature. Say, for example, if you were adding refrigerant to a system, you might add a pound of refrigerant. You wouldn't add it until it was at a certain pressure. As for a consumer AC system in a vehicle, I couldn't tell you how much to add. Look for a reference of the amount of refrigerant in the system and start by adding half that amount maybe?
Using 134a plus refrigerant in a 2001 GMC Sonoma is not recommended. The vehicle's air conditioning system was designed for R-134a refrigerant, and adding a blend or "plus" refrigerant can potentially harm the system or lead to improper cooling. It's best to stick with the manufacturer-recommended refrigerant to ensure optimal performance and avoid damage. Always consult a professional if you're unsure about refrigerant compatibility.
The 1998 Chevy did not come with Freon (R12) installed. Freon was banned beginning in 1996. It contains R-134. You have a leak that needs repairing before adding more refrigerant.
