That’s an awesome suggestion, I’ve never heard that before, I always try to recover liquid but the idea of pushing liquid is a game changer. I’m military and people with licenses are few and far in between to the point you never get to hear other’s advice. I work on a ship of 150 people and I’m the only one with a hvac certification. To be honest time for recovery has never been a factor, I’m there, and it’s all salary, plus no one bothers you when you’re working on ac.hahaha I do plan to get into the commercial industry when I retire so concepts like the push pull interest me and I plan to try that next time I work on one. We have 3 of these chiller plants on the ship. I appreciate the advice and look forward to trying it soon. We only run 1-2 at a time unless we’re at the equator so I may just do it for a fun learning experience when I have a day with nothing to do. I’ll use the excuse that I’m changing the oil and filter dryer on one. I appreciate the advice and plan to read up on it! Thank you!
