Buying Guide: Best Automotive AC Vacuum Pump

Understanding the Importance of an AC Vacuum Pump

When I first learned about automotive AC systems, I quickly realized how crucial a vacuum pump is for proper maintenance and repair. An AC vacuum pump removes moisture and air from the system before charging it with refrigerant. This step is essential because any moisture left in the system can lead to corrosion and failure of components.

Types of AC Vacuum Pumps

I found that there are primarily two types of AC vacuum pumps: single-stage and two-stage.
