If he is following good procedures and can't pull down a good vacuum, and his pump is doing a good job, he will need to find the source of the leak, hence a shot of R134a in the system, gauge and manifold set, and then use an electronic leak detector.
Just went through this with a brand new electronic manifold. The micron sensor was defective; leaking.
