Introduction – Welcome to electronics

Welcome to the training process for Heating, Ventilation, Air Conditioning and Refrigeration.

Electronics and the use of electricity will be part of your job every day. As you move forward in your career you will find that 90% of the problems that you come across are electrical. The remaining 10% can be split between mechanical and customer education. Surveys of HVAC contractors have shown that the biggest gap in vocational training is in the understanding of electronics and the trouble shooting steps to quickly and accurately find electrical problems. When we look at test results and where students struggle through the course material that will be presented to you over the next year we find that the key difference between those who achieve high academic standing and those who don’t is the understanding of electrical troubleshooting and principles.

What supplies and equipment will you need?

As a student you will need a few tools as you move through this course if you wish to do the projects and get the most out of it. You will need a digital meter with readings for resistance, amperage and voltage. You will need a flat headed screw driver, a Phillips screw driver, a set of wire strippers/cutters. If you are working in the classroom environment the instructor will have wiring boards that you will use. These boards include two standard household light switches, a plug, a transformer, a two pole contactor, a  relay with normally open and normally closed contacts and a 24volt coil, a relay with normally open and normally closed contacts with a 120volt coil, and two standard 120 volt light bulbs with sockets. You will also need some wire of different colors. We recommend using black, white, red, and orange to make it easier to understand the work that will be presented. If you are working on your own, a layout of the boards is LINKED HERE ALONG WITH ORDERING INFORMATION so you can put this together before you begin.

We wish you the best of luck as you begin your training and it is our hope you succeed. The material is sometimes difficult and a lot will be expected of you both here in school and once you begin your training in the field. The rewards are worth it. Remember learning is fun. Enjoy, learn, and do not over analyze what you are presented with. Now let’s begin.
