What are A/C service ports on a car?

A/C service ports are access points technicians use to measure pressure, diagnose HVAC problems, and safely add refrigerant to your vehicle’s air conditioning system.

What is the difference between the high and low side ports?

The low side port is typically used to add refrigerant and evaluate suction pressure, while the high side port is used to monitor discharge pressure and overall system health.
