Hello, and thanks for reading this.
A bit of history. I have worked for a customized commercial HVAC manufacture for the last 12 years, first as a electrical assembler working on control panels, then testing units to make sure everything in functional, setting the charge, ensuring proper cooling and heating. Doing this I have learned a fair bit about these system, and am thinking about switching over to service. I was wondering about how to go about this. I do not have the time or money to go through a school program, and I already know alot of what they would teach me, no where near enough to consider myself a tech or mechanic really though. The shop has basically taught me the bare bones, and there are skills that I need to improve. I would really appreciate some advice.
