people who experienced

I enjoyed and really liked Trevor’s interactive teaching, always getting the class involved and always so enthusiastic! I’ve already had coworkers come up to me and ask me how to check net oil pressure or how to check for blow by and I’ve told them with absolute confidence how to check each.

The interaction from fellow technicians during the course giving some of their onsite experiences. Along with Trevor’s detailed answers on what we should look for while doing pms before the failure occurs. Trevor explained the use of the many resources out there and took the time to explain in great detail. I would highly recommend this course to anyone who wants to take their skills to the next level.

What a really like about this program was the depth of knowledge that was presented to the class. This information was spread across multiple brands and covered various compressor sizes and applications that we would see in the field. Hands down best refrigeration class I’ve ever been to, I recommend going through this program at least once a year to stay fresh on the topics at hand.
