New A/C machines drive efficiency

The new A/C service standard — J2788 — and corresponding service machines are covered in this course (LBT-227 Why J2788 Standard with Bob Pattengale). Instructor Bob Pattengale explains the difference between the new J2788 equipment and old equipment underscoring that using the latter to service A/C systems is less efficient and time consuming, plus the new machines offer better recovery efficiency and higher charge accuracy.
