The side of the compressor that is normally charged is the low-pressure side. This is where the refrigerant enters the compressor after absorbing heat from the environment. Charging typically involves adding refrigerant to the system through the low-pressure service port, allowing the compressor to efficiently circulate the refrigerant throughout the system. Proper charging ensures optimal performance and efficiency of the HVAC system.
Refrigerant is typically charged into the low-pressure side of the compressor to ensure the system operates correctly and efficiently. Charging refrigerant into the high-pressure side can lead to issues such as system damage, inefficient operation, or inadequate cooling.
You should charge the refrigerant on the low-pressure side of the compressor, typically through the suction line or the service port designated for low pressure. This is because charging on the low side helps ensure that the refrigerant is in a vapor state, allowing it to mix properly with the oil and preventing damage to the compressor. Always follow the manufacturer's guidelines and safety procedures while charging.
The low pressure side of the ac system is the ac hose that runs from the inside of the vehicle to the ac compressor. The high pressure side runs from the ac compressor to the condensor in front of the radiator. Follow the ac hose from the compressor back to the body and you will find the charge fitting. It is smaller in diameter than the high pressure side. You would need a different adapter to hook up to the high side.
read the manufacturers logo on the side of the unit and weigh the charge
You charge a compressor on the low-pressure side, typically through the service port located on the suction line. This is where the refrigerant enters the compressor, allowing you to add refrigerant safely. Charging on the low side helps avoid over-pressurization and potential damage to the system. Always ensure the system is off and follow proper safety protocols when charging.
High side, If you charge liquid on the low side it can cause the valves of the compressor to break.
port is next to the compressor under the car...
Should be a pressure switch located on the top of the air drier/acculmulator -- jump this with a paper clip and clutch should pull in allowing you to charge system
You would charge it from the low side port.
Follow the larger hose from compressor this is low side
low side of a/c is the larger diameter line it the smaller fitting(charge side) vs. high side is your smaller line larger fitting
Follow the larger line from compressor maybe near the drier on the passenger side firewall
