Many times, we only learn things that we working on and thus, overlooked on other things that might produce better results. I thought we should know about a lot of things but not necessarily need to go very deep. That’s why I wrote this ebook. The goal is to let engineers learn about HVAC components that they otherwise not able to unless they worked on related projects. With that, I believe they have a clearer path in their future and perhaps, they can accelerate their progress towards better efficiency HVAC systems.
