Purpose of Seminar

Being able to understand, operate, maintain, and troubleshoot your own air conditioning system is what this HVAC course is all about. It was created to bring students up to speed in their skills and knowledge as quickly and safely as possible. Taught by instructors who have been in the technicians’ shoes, the practical, commonsense approach we take in presenting this course makes it perfect for novice technicians as well as multicraft tradespeople, or even more experienced HVAC technicians who need a well-rounded refresher or who are looking for new ideas and solutions.

Created to have high impact in a short amount of time, this program is designed to extend equipment life, improve HVAC/R efficiency, save energy costs, and enhance comfort control, while establishing a culture of environmentally safe and technically sound work practices among employees.

Discussion Topics

Day 1 of this program has been designed to give the student a broad introduction to air conditioning and refrigeration systems, including every-day operation & important refrigerant safety practices. The course is a great overview for maintenance technicians, multi-craft tradespeople, building managers, HVAC technicians or anyone who wants to improve their AC&R operation and maintenance skills. Understanding basic AC&R operation & how to properly handle EPA regulated refrigerants is the goal of the first day of this training course.

Fundamentals of AC&R

  • Air conditioning versus refrigeration
  • Laws of thermodynamics and heat transfer

Regulation, Codes and Standards

  • New Energy Efficiency Standards (S.E.E.R.)
  • EPA Section 608 of the Clean Air Act
  • Technician licensing, testing and certification

Compression Refrigeration Cycle

  • Basic system design
  • Follow-the-Heat TM


  • CFCs, HCFCs, HFCs, Inorganics
  • Zeotropic and Azeotropic Refrigerant Mixtures
  • Refrigerant safety Including R-410A
  • EPA Section 608 Significant New Alternative Policy

Refrigerant Oils

  • MO, AB, POE, PAG, PAO Oils & Properties
  • Maintaining Oil Quality in Your AC&R System

Major AC&R System Components

  • Evaporator, Compressor, Condenser
  • Metering (Expansion) Device

Day 2 is designed for people who already have a good foundation in AC&R components and systems. 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. An introduction to commercial and industrial chillers will be covered too, as well as regulatory laws and energy conservation. Overall, the second day of this program is designed to help you get the maximum life out of your AC&R systems while keeping it up and running as efficiently and consistently as possible.

EPA 608 Technician Certification Testing

Testing for EPA section 608 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.
