Just wanted to get some input before I start my new job on Monday. I was laid off two weeks ago from my last job as a commercial tech working on RTU's, Dry-Coolers, server room units, and water source heat pumps after our company lost a few big contracts. I am starting new job for a refrigeration company that takes care of all the Startbucks in the area, gas stations, restaurants, etc. I have some refrigeration experience and am bummed I couldn't land a supermarket refrigeration job just yet but I am still looking. Any input on what I should brush up on before I start on Monday. According to my supervisor I will be thrown into service right away and that they are comfortable working with my current skill set. I have done mainly HVAC service work, not a whole lot of refrigeration, any input on what to be ready for and what to brush up on is much appreciated.
