After 5 years of working as a hvac/r ref tech for a large fast food chain, the in house facilities maintenance department was downsized and my position was part of the cut. My former supervisor encouraged me to get my C-20 and assured plenty of work thrown my way so, I am looking for the best way to pass the exam by spring startup.
I did okay in college with the HVAC course and have the 608 universal cert. but it's been a while since I have taken a test and would like advice on training for the exam. Are there good self paced online courses? Should I just pony up the 500 buck and take one of the many courses online? Thanks.
