“I took the HVAC/Refrigeration PE exam for the first time and passed. I feel Dr. Tom’s class was not only very critical in my passing of the exam, but it was exactly what I was looking for in a review course. His class laid out the important subjects and gave me a guide to be successful. I was very pleased with all the materials the class gave to aid in my success – study guides, weekly schedules, practice problems, video lessons, and a question/answer forum. I feel if you are taking the HVAC/Refrigeration exam, Dr. Tom’s class will cover all topics you need. Thanks for all your help Dr. Tom!”

“I PASSED!!!! Your step by step course really did make all the difference! I took the HVAC & Refrigeration exam. This was my third attempt at taking this thing. The first time I took an in-person PPI study course, a lot of theory, not great with the problem practice. The second time I tried to study on my own…not good. And my third time I found you and your course! Your class was really great because I felt like in every video, you genuinely and sincerely wanted to help us pass this test. The course is one of the most reasonably priced course I could find and discovering that it was also so amazing was really a pleasant surprise. Thank you so much for everything!”

“I passed the HVAC and Refrigeration exam! The first time I took the exam I studied on my own. The second time, I followed Dr. Tom’s 20-Week study plan as closely as I could. The structure that his lessons and problems provided was very helpful in refreshing my understanding of the concepts in each topic. Going into the exam, I felt very much more prepared than the first time. In fact, the exam seemed “easier,” which I can accredit to using Dr. Tom’s review course. Dr. Tom, thank you for your course and the passion that you display while teaching it.”
