Seminar Overview

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 AC&R systems while keeping it up and running as efficiently and consistently as possible.

This seminar is just $550 per day or $1100 for both days. You can also combine it with our Boiler Operation course for a comprehensive 4-day HVAC Workshop.

EPA 608 Technician Certification Testing

Testing for the EPA 608 Technician Certification is optional. 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. Students may take the test at the end of day 2. While we cover material relevant to the test and make every attempt to help our students pass this exam, we cannot guarantee individual success. Therefore it is recommended that students who want to take the test attend both days and plan time to study beforehand.
