I was very impressed with the curriculum and the instructors. All of the textbooks and various materials you receive as well as the IGSHPA certification alone is worth the cost of the class. This is a great investment.

- Scotty Brown, Cal-Tech Well Pump & Compressor

Taking this course was well-spent money. The course instructors were the real McCoy, people that have worked in this industry and helped develop the technology behind it. I've recently taken some other courses put on by suppliers and they are nothing close to the HeatSpring courses.

- Stacey Raymond, Geotherm, Inc.

I think this class was an excellent prep for the test and made you feel confident.

- Robert Kaiser, DW Hunter HVAC

I enjoyed this course quite a bit. It was very informative and gave me a great understanding of exactly how geothermal works and all of the components that go into designing and installing a system!
