TESTIMONIALS

Hi Ken,
I ordered this self study course from you in September. Between work and family obligations I didn’t open it until two weeks ago. I wanted to let you know that I finally got around to taking the equipment exam today. Scored an 84.6% on my first attempt, I don’t believe that would have happened without your self-study course. Thank you for your help in preparing for the exam, you are providing a great service to those of us in the industry.
Best Regards, Owen

Hey Ken,

This is Collin. I took your October class last year (2023) with a couple of coworkers. I just wanted to text you and let you know that since then we have all passed and that I would say in large part is due to your class. Just wanted to say thank you again and have recommended you out to a couple of other guys getting ready to take your course.

Hi Ken,

I passed my exam yesterday (Category 2 HVAC) on the first time through. They had a lot of questions off every small chart from both IFGC AND MMC. It threw me off because I was looking in the body of the code. There were only 3 or 4 from the law portion. Thank you for your book and help. I'm going back to do heat and cool service.

Just wanted to reach out and thank you for your class and study manual. I passed my category 2 test on second approach. On my first try I missed the mark by 13 questions but on second I did well, took more time to re-read all code books and study the math.

Hey Ken, I just wanted to reach out and say thanks for the pre test study Info. I passed the darn thing and your material was very helpful!

Good evening,

I took your class back in October and I just passed the HVAC equipment exam on first try! I will say there was quite a bit of solar energy, LP , manual d and ventilation rate questions on the exam. There wasn’t any gas pipe sizing questions and not very many venting table questions.

The study guide really helped and I’m looking forward to taking my service tests as well.

Best,

Mitchell
