Hello guys, I have 12 yrs in the HVAC industry, the vast majority as a residential and light commercial tech, but the company I started with at the tail end of last summer has some commercial clients with refrigeration equipment. I have occasionally worked on refrigeration equipment under a previous employer, but it was so infrequent, that I couldn't really get a feel for it. If I ran into a problem and had a question, the owner/manager could usually walk me through the issue, but due to the infrequency, I never really felt comfortable with the R. Unfortunately, I feel my new boss knows even less, and honestly, I think we both know we're a little over our head on some of the more complicated refrigerant issues that arise sometimes. I hate that feeling, and want to learn more about the particulars of R systems.
I want to know what I can do on my own time to learn more about the equipment and become comfortable and confident when dealing with it and make myself more valuable to my current and potential future employers. I came into the HVAC field the apprentice route, no formal in-class training, mostly in the field training with occasional training seminars and update classes by manufacturers of residential equipment. Universal EPA license. I wouldn't be opposed to taking classes, but I don't think I could balance traditional classes with my workload, which is always 40 plus hrs in "slow" seasons and much more in "money" seasons, not counting on-call rotation. I would love to hear any advice you guys have for online resources, preferably free, but if you know of any paid "at your own pace" online resources/classes that you highly recommend, I would like to hear about them as well. Heck, if there's an "old-school" book that is a must buy, I want to hear about that as well!
Thank you in advance for your help.
