NATE
Certified Air Conditioning Technician Training

Sample Video Lesson

Chris Compton provides a lecture on the basics of the direct expansion refrigeration cycle. Each of our courses is rich with photos and videos that help intensify the learning process.


The new Technician entering the trades needs the core skills to succeed. This accredited training track, called the NATE Certified HVAC Technician Program ensures that the new technician succeeds with a combination of videos, video lectures and more.


The academic program is taught by an experienced team of Certified Master HVAC Educators.


The NATE Certified HVAC Technician Program (NCT) is a comprehensive online HVAC education program encompassing a well-rounded set of skills used by installers and technicians who are seeking NATE Certification.


It starts with cultivating new technicians into the Ready to Work program with all the essential skills needed to start a career in HVAC. Then, it covers all the NATE Core areas with a rich selection of foundational courses, and then focuses on Air Conditioning Specialty at the Service Level. The content presented in each course targets learning objectives that have been identified by HVAC industry groups (HVAC Excellence, AHRI, NATE, HARDI, PAHRA, and ACCA) as critical knowledge areas for an HVAC technician.


North American Technician Excellence (NATE) is the nation’s largest and most recognized non-profit certification organization for heating, ventilation, air conditioning and refrigeration technicians. NATE certification tests represent real-world working knowledge of HVACR systems. Developed by a committee of industry experts nationwide, all the NATE tests are rigorous, knowledge-based, multiple-choice tests designed to validate a technician’s knowledge.


You can read more about NATE at: www.natex.org. HVACRedu.net’s NCT Program is specifically structured to teach foundational skills to individuals who are new-to-the-industry and non-certified installers and technicians who want formal education to upskill their knowledge and prepare for licensing or certification exams.

Transcript from the sample course video

Today we are talking about moving heat as the purpose which is a very fundamental concept of the refrigeration cycle. As it says on here on connecting the dots when analyzing the refrigeration cycle that’s what you have to do, you have to connect the dots. This particular session is about the evaporator side of the cycle. Remember there’s four required component parts for a mechanical compression refrigeration cycle. That would be the condenser, the metering device, the evaporator and the compressor. And in our 141 basic refrigeration cycle course that’s where these videos are going to be placed so that to help you better understand that particular course and the refrigeration cycle in general. For this session on the evaporator side the objectives as it says there in the slide recognize how the refrigeration cycle moves heats because that’s the whole idea that’s why we use the refrigeration cycle is to move heat. Recognize how heat is moved into the refrigeration cycle and that’s the evaporator part that’s where the heat goes into the cycle. That’s where its captured. And then understand how heat energy affects evaporator performance. So, we’re going to try to beat you over the head with this concept and these ideas and how to use the refrigeration cycle, how to analyze it, how to understand first of all what’s normal. Normal is what you have to understand first before you go to abnormal. So normal if you can understand normal then you can start troubleshooting because if it’s not normal then its abnormal.

So how do you go from the neat organized schematic wiring to the reality of the wires all over the place? And here is just a couple of screenshots of typical wiring that you guys see every day. I like the one over here that’s a nice, neat commercial HVAC electrical panel as they tend to be but are often not very neat. So real-world wiring diagrams, let’s look at a few schematics that you would get from the manufacturer. It will probably be pasted on the inside of the electrical panel in the equipment somewhere. You’ve got the pictorial over here and then shown on the righthand side pretty straightforward, nice, neat but sort of scattered around. Then you have the ladder on the left, which is super neat. I have a bunch of comments about this, so we’re just going to go along through here. Here’s another set this one a little more complicated, a little bit more loads, a lot of stuff going on. Nothing that’s really complex unless you don’t know how to read a schematic and how to take that schematic to the real-world wires. That’s the challenge, and it’s been the challenge for a long time for a lot of techs. The bad news is to get over the challenge is not easy. The good news is once you get over the challenge, it’s like shooting ducks in a barrel, or maybe its fish?


Commercial Refrigeration for the HVAC Technician

Commercial Refrigeration for the HVAC Technician

Experienced HVAC technicians spend time wondering how that walk-in freezer or ice machine works. This in-depth program is specifically intended for experienced HVAC technicians. Taught by Dick Wirz, this program answers most of the burning questions asked by field technicians.

 

With a combination of videos and the textbook written by Dick Wirz, the HVAC technician finishes the course complete with new knowledge that can be put to use immediately. The entire team of Certified Master Educators is available for questions related to the training.

 

We will compare things you’re already familiar with like space temperatures and common components of basic AC systems to those of commercial refrigeration systems. We will examine evaporators, condensers, compressors, metering devices, controls and accessories, and the refrigerants commonly used in commercial refrigeration. We will review the important terminology. At the end of this course we will cover some system troubleshooting, giving you a chance to put your knowledge to work on the 9 most common system problems.

 

We will compare things you’re already familiar with like basic AC systems to those of commercial refrigeration systems. We will examine compressor motor controls, retrofitting, recovery, evacuation, and charging; various supermarket refrigeration systems, walk-in refrigerators and freezers, and commercial ice machines so you can identify the components, their functions, and the refrigerants belonging with each application. After you have a good understanding of the equipment, we’ll explore appropriate temperatures for products kept in that equipment. And finally, you will understand when to apply TROT (The Rule Of Thumb) in the absence of a manufacturer’s recommendation.

Transcript from the sample course video

I’d like to welcome everybody to HVACRedu.net 153 Building Automations Class Sequence. I’m your instructor, my name is Ron Auvil, and we will get a chance to do some introductions in a few minutes. I hope that you had the chance to look at some of the basic controls here. I’m looking forward to teaching you guys everything that I know about building automation, and I think that you’re going to find that that’s going to be quite a resource. I’m really excited about working with each one of you on this particular course. Now a couple of assumptions here in this course, we’re going to start with here tonight with 153-1, which is HVAC fundamentals and one of the assumptions is that you got a copy of my textbook HVAC Control Systems and also a copy of the workbook. And I want to make sure you have some of these available, that’s going to be a great resource. I am going to be referring to specific page numbers in this textbook as we go through these individual modules. I want to bring up just a couple of approaches here talk about a couple of initial things and I want to bring up a couple other issues as we get rolling with this, and some of the ways I’m going to approach this. And I want to make sure that when we’re going through these modules that you have a pen and paper in front of you because I’m going to be talking about a number of things that are in addition to what you see up here with these slides. And that is going to be very important because it’s going to reflect my years of field experience that I’m going to be pouring into these courses that I want to make you aware of. And when we are going through these individual modules in Building Automations, I want you to picture in your mind if you can, that you and I are in a service van together and we are going to a job site. We are either going to be doing an installation, or we are going to be doing a service call for building automation.
