Who's Behind It

Description of image

My name is Sam Bilamjian, and I bring over 25 years of experience in the HVAC/R industry. Throughout my career, I have worked extensively across residential, commercial, and industrial systems, developing strong expertise in installation, service, and diagnostics. In addition, my 14 years of teaching experience have highlighted the significant gap that often exists between classroom theory and real-world application, an issue this resource is specifically designed to address.

Why I Built This

Good training materials that are free, accessible, and written by people who've actually done the work are hard to come by. I created this site to give apprentices a reliable place to learn at their own pace, without the noise.
