Seminar Overview

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 and experienced HVAC technicians alike.  This air conditioning and refrigeration training  course is designed for anyone who needs to understand basic operation, maintenance, and  troubleshooting of air conditioning and refrigeration systems in order to improve efficiencies and uptime in commercial, industrial, or residential locations.

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.

Day One - Discussion Topics

Day One of this air conditioning and refrigeration training provides 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. The goal of the first day of this training course is to understand basic AC&R operation & how to properly handle EPA regulated refrigerants.

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™


  • CFCs, HCFCs, HFCs, Inorganics
  • Zeotropic and Azeotropic Refrigerant Mixtures
  • Refrigerant Safety Including R-410a
  • EPA 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 Two - Discussion Topics

Day Two of the air conditioning and refrigeration training is 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. Also covered are 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.

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.
