  a c troubleshooting guide: EPA 608 Study Guide Hvac Training 101, 2019-12-06 HVAC Training 101 is a site visited by over 100,000 enthusiasts monthly, who are interested in becoming HVAC technicians. The site initially began as the passion project of a retired HVAC technician. The site quickly gained popularity, building a strong community of aspiring HVAC technicians. Currently, it is managed by a team of ex-HVAC technicians with decades of experience in the industry. Head over to HVACTraining101.Com to learn more. We began by writing about how to become certified as an HVAC technician. With rules and certifications varying for each state, it was a challenging task. We had a few friends in other states help us out, but for some states, we had to dig really deep to find the information needed. Our audience at the time was very happy with the information we provided. At this point, we started getting many questions about EPA 608 certification. Once you get the education and experience needed to become a technician, prospective employers will ask for certification to handle refrigerants. When we started writing about how to become certified, viewers again requested we write a study guide to help them prepare for the 608 exams. The study guides out there were dense and had much more information than was needed to pass the test. This inspired us to embark on a journey to write the simplest study guide for the EPA 608 exam, which would still cover all the necessary information. We hope we have achieved our intended objective. The journey to becoming an HVAC technician can be long and arduous. We congratulate you on taking this path and wish you the best in cracking the EPA 608 exam.
