Seminar Overview

Available in both virtual and in-person, instructor-led formats, the goal of this two-day Air Conditioning and Refrigeration course is to provide a broad introduction to air conditioning and refrigeration systems, including everyday operation & important refrigerant safety practices. The course is a great overview for maintenance technicians, multi-craft tradespeople, building managers, HVAC technicians, or anyone seeking to improve their AC&R operation and maintenance skills.

Students are taught common practices and some "tricks-of-the-trade" for general operation and maintenance of their AC&R systems. They will learn about maintenance schedules and servicing, system diagnostics, troubleshooting, and fine-tuning to gain maximum efficiency. The course also covers an introduction to commercial and industrial chillers, regulatory laws and energy conservation. Overall, we will help you get the maximum life out of your Air Conditioning and Refrigeration systems while keeping it up and running as efficiently and consistently as possible.

This seminar is just $1,195 for both days. You can also combine it with our Boiler Operation course for a comprehensive 4-day HVAC Workshop.

What is Virtual Instructor-led Training (VILT)?

Virtual air conditioning training provides your workers with all of the benefits of a live classroom, coupled with the convenience and affordability of online training. To access virtual air conditioning and refrigeration training, an employee only needs a computer, webcam, microphone, and internet connection. Training can be completed at home or in the workplace, without the costs associated with live classroom instruction. Employee safety is also improved, as virtual training comes with built-in social distancing.

Online air conditioning and refrigeration training courses are led by skilled instructors with years of classroom and industry experience. Workers receive virtual face-to-face instruction through video conferencing, with opportunities to engage instructors and classmates in meaningful discussion of A/C topics. Information retention is improved through pop quizzes, exercises, and simulation training.

EPA 608 Technician Certification Testing

Section 608 of the Federal Clean Air Act requires that all persons who maintain, service, repair, or dispose of appliances that contain regulated refrigerants be certified in proper refrigerant handling techniques by passing the EPA 608 Technician Certification exam. The EPA 608 exam is included in this course and is administered at the end of the second day of training, although attendees are not required to take the exam for successful completion of the course. While we cover material relevant to the test over the course of the training, this course is not designed to specifically prepare you to take the exam. Therefore we highly recommend that attendees who want to take the exam attend both days of training and take time to study beforehand. We mail out the EPA 608 study guide to all course registrants the day after registration to give you ample time to prepare. You can also download a PDF of the study guide below.
