Bluon HVAC has teamed up with measureQuick to provide technicians with "just-in-time" training and education. Here, Jim Bergmann explains why it's important to test your vacuum pump before connecting the pump to a system. This can save you time and effort, and ensures you have a functional vacuum pump before you start working.
