This is a five-day class that can be presented as a complete package or taken in one or two day module increments.
|
Air Conditioning and Heat Pump I |
In this session, we focus on heat transfer, the relationship between temperature and pressure and an introduction to the refrigeration cycle. The purpose of this class is to develop an understanding of thermal dynamics. This class creates the foundation needed to develop an understanding of the Refrigeration Cycle.

Air Conditioning and Heat Pump II |
Day Two: Refridgeration Cycle
In this class, the students will develop an understanding of the different components in the cycle and how they interact with each other. The students will learn what the refrigeration does in each component and how the conditions inside the house and outside have an affect on the component and the refrigeration inside. We will also spend time understanding what super heat and sub cooling is all about and the importance of being able to take these measurements. The overall objective of these first two days of training is to get the students to learn and understand the refrigeration cycle.

Air Conditioning and Heat Pump III |
Day
Three: Procedures
In this session, we focus on procedures and techniques for refrigeration
recovery, evacuation and charging both air conditioners and heat pumps.
There will be review of the refrigeration cycle and time spent on further
understanding the importance of measuring super heat and sub cooling.
We will also talk about service procedures, such as leak detection and
brazing.

Air Conditioning and Heat Pump IV |
Day
Four: Troubleshooting
In this class, we focus on troubleshooting and servicing residential and
light commercial air conditioners and heat pumps. We begin with
a brief review of the refrigeration cycle and then perform some troubleshooting
problems. We will then cover proper service techniques regarding
component replacement, driers, contamination, piping and equipment replacement.
Our goal in this class is to get the students to see how all of the components
work as a system and to be able to use symptoms to help diagnose problems.
The students will learn what it takes to be accurate and effective troubleshooters.

Air Conditioning and Heat Pump V |
Day Five: Controls
This class is designed to focus on the electrical side of the system. The students will have a brief review of some basic electricity and we will spend the day understanding the controls related to air conditioners and heat pumps. Transformers, relays and contactors, defrost boards, pressure and temperature switches, all of these controls and more will be reviewed and talked about. There will be opportunity for the students to receive hands on experience during this class on our training boards using some of the mentioned controls. Before attending class, the students should have attended a Basic Electricity Class, either ours or someone else's. We can incorporate a Basic Electricity class into this format (Controls I). It would then be the fifth day of training and the Controls class would be the sixth.
