Top 20 HVAC-R Troubleshooting Problems (Free E-Book)
This troubleshooting handbook contains 20 separate troubleshooting scenarios designed to test the skills of HVAC R technicians. In each situation, all the information necessary to arrive at a diagnosis is provided.
The solutions to the problems are presented in a separate section at the end of the book.
If you are working individually with this handbook, use it to test yourself. Review the problem and any related graphics or wiring diagrams, then, record your diagnosis before checking your answer in the solutions section.
If you are a serviced manager conducting in-house training sessions, or an instructor facilitating a classroom or lab training exercise, you may print and photocopy the problems and diagrams for classroom distribution.
