EPA 608 Certification Test Prep Class

This class is everything you need to pass the Universal EPA 608 license exam in five days. The course includes five lectures, five daily quizzes and a full-length practice exam with questions structured just like on the real exam. The daily classes include approximately 30 minutes of a video lecture with an associated practice quiz. In the course we cover a proven study method to follow for those who have trouble studying by themselves. This class is made for those who want the license as soon, and easy, as possible. If you only want one certification "Type" you only have to participate in the "Core" classes and the "Type" classes for the certification you want.

Video "class-time" saves you from memorizing 100's of pages in text books filled with redundant information.

You'll be comfortable answering the computerized test questions after you finish the practice exam.

Use any internet-loving device, phone or computer, to study in down time while you're already at work.

Imagine this: Next week, you have your EPA certification... wow. Why did it take you this long? You got your raise. You make better sales and keep your jobs. Now you can afford that new veto pack.

Study between your jobs within the comfort of your own office...truck.

Study sheets give you the facts you need to memorize on note cards you can keep in your pocket throughout the week.

A human instructor is available to answer any questions you come up with.

3 Steps to get EPA 608 Certified Fast

"I tried two different self-study books. Having a teacher cover the material was worth the extra cost. Also having the schedule with a deadline made me finally just do it."

- Casey, Refrigeration Repair, Commercial Systems and Services

"The videos covered what I needed to know and the practice questions solidified what I needed to review. The five days were busy but over fast. I recommend this class to all the technicians we hire."

- Robert B., Service Manager, Metal Mechanical

From the Instructor

Most technicians consider getting their EPA 608 card for two years before they finally go through with it.

100% of those technicians regret having not started their real career in HVAC/r sooner.

I created this course to help the normal tech who is amazing at their job but intimidated by classwork. This is the problem: white-collar folk making the hoops to jump through for us blue-collars though we learn very differently. Tradesmen, and women, notoriously learn faster by seeing and doing versus reading a fat code book on a wheeled chair in an air conditioned cubical. That is why in my class I put all of the information you need to know in classes you can watch as I cover the material with gratuitous amounts of legit practice questions. I even made tables and study "cheat-sheets" with exact material you need to memorize. This way, whether you are in the field or managing it, you can pass the exam quickly.

I was born in the trades, molded by it. I've watched the best technicians make a fraction of what they are capable for years until finally just getting their certification. I invite you to enroll in this course now and after one week you will be ready to obtain your EPA 608 certification and move on in your career with better pay and better jobs.

Frequently Asked Questions

What is the EPA 608?
EPA is short for Environmental Protection Agency, a government organization that enforces the Federal Clean Air Act. This organization has enough power to shut down a business...and pretty much everything else in your life. Section 608 of the Federal Clean Air Act requires that everyone who maintains, services, repairs or disposes of appliances that contain regulated substances (refrigerant chemicals) be certified in proper refrigerant handling techniques.
Why do I need an EPA 608 card?
You need an EPA 608 certification card because it's illegal for a supply house to sell refrigerants to anyone without showing their EPA 608 card stating they passed the exam and that they know how to properly handle refrigerants. Improperly handling refrigerants can bring fines as high as $37,500 per day, per violation to you and your company. If you are caught working on a refrigerant system without a current card you can also be hit with that fine.
What experience do I need to get the EPA 608 certification?
You need to be able to pass an exam to get the EPA 608 certification. The exam to get the card requires knowledge that has very little to do with field experience. It is common for warehouse workers, apprentices and laborers to get their EPA 608 certification without having ever seen an installed A/C unit. On the flip side, even five-year installers will take this course and have to study just as hard because it is all new material.
How long will it take to get the EPA 608 certification?
As fast as three days from now but normally seven days. Trade Masters Online has the system set up for you to get certified this week. To take the EPA 608 test online you you have to schedule at least three days ahead. If you already know all of the material, all you have to do is take a 2-4 hour long test. If you don't know everything, like a normal human, then you'll need to take the prep course first. Most students schedule their test 5-7 days from their start date of the class.
What is the EPA 608 test like?
It is a 100 question test you have to score a 70% to pass. The questions are on specific information in the EPA Section 608 laws. It is a proctored exam and has to be by a licensed person who watches you and your computer so you don't cheat.
Why do I have to take the test?
The EPA 608 test is a way for refrigerants to be regulated away from just anybody to access them.
How hard is the test?
You will not know any of the answers if you do not study. The material is new to seasoned techs and educated engineers. Go ahead and enroll in the free class to take the quizzes with questions just like on the real test.
What can I do without the EPA 608 certification?
You can make sales, diagnose system malfunctions and even install the entire HVAC system in a home but you CAN'T open or close a valve to a charged system. You can't do anything with the refrigerant chemical. You can't even connect your hoses to the schraeder valves of a charged system.
I just enrolled in the class. What's next?
Start on the first day material. The instructor, Carl, will contact you within the next few days to answer questions and set up your test.
What languages can I take the EPA 608 online test in?
You can take the online EPA 608 test in English or Spanish. You choose the language when scheduling your test time with the proctor.

Frequently Asked Questions

How long do I have access to the course?
You have access to the course for two weeks. The goal is for you to take your exam ASAP after the last class. We want you to finish this right away and we can only keep your enrollment for so long until we have to let other students in. If for some reason you need to extend your time all you have to do is contact the instructor. If we can't schedule your exam until after the course time is over, we will extend your enrollment until after your examination date.
What time is class?
Everyday the lecture video is uploaded to the course page before noon, Pacific Time.
How much time is required everyday?
This course is made for the working tech. We recommend to spend at least 60 minutes daily for five days and another two hours for a full-length practice exam. The amount of personal study throughout the week varies between students but we recommend one hour a day reviewing past notes.
Can I rush through the course?
Yes, but the class is designed to introduce a lot of material every day. Even the best techs can get overloaded so we strongly encourage the five-day course.
Can I only get one "Type" certification?
Yes! The EPA 608 license has four parts: core, small appliances, high-pressure appliances, and low-pressure appliances. You only have to pass the core and then the appliance types you want. For instance, if you only want to work on high-pressure appliances, which is common for residential air conditioning technicians, then you only have to pass the core and the high-pressure exam portion. This will require participation in days 1, 2 and 4. We recommend you participate and follow every lecture as material among the sections is inter-woven with each other.
When can I contact the instructor with a question about the material?
Good news! If your question is NOT in the course material then YOU DON"T HAVE TO KNOW IT! However, you can contact Carl directly, through email, or his carrier pigeon, Stubbs.
What is the EPA 608 license?
Anyone handling refrigerants must carry the EPA 608 license for the equipment they are working on. For example, a refrigerator repair technician would need a Type I license, an industrial chiller tech must have a Type III license and an air conditioning repair tech for small residential homes would, generally, need a Type II license. This class is tailored to those seeking the Universal license, meaning, with this license you can work and all three types of equipment.
Do I need to purchase the books?
Nope, we give you everything you need after you sign up. You can download the notes and print them up for physical copies or just view them as PDF on your phone/computer. However, you do NEED a physical copy of the lecture notes. Students who purchase the class with books have a much higher percentage of passing the EPA 608 exam than those that buy the standard class and don't print papers themselves.
What device can I use to access the course?
Whatever device you are reading this sentence on is capable to participate fully in all class material. Any computer, phone or tablet with internet will work. Any Windows, Linux, Apple, iPhone, Android, iPad, laptop or TV with an internet browser will work.
Do I have to be a citizen of the United States?
No, You do not have to be a citizen of the United States to get your EPA 608 certification. You do need some official form of identification, such as a work ID, government ID, or passport. The certification is recognized around the world.
Do you offer group rates or discounts for the EPA 608 certification?
Yes, we offer steep discounts. Email [email protected] with what you are looking to do. We have three types of discounted plans: 1) Groups: many people enrolled and paid for at once. 2) Accounts: small discounts that get larger the more purchased over the length of our relationship. 3) Partnership: Unlimited viewing and access for your company.
How should I study for the EPA 608?
The EPA 608 test is pretty difficult. This class covers a whole lot of information that you need to be able to understand and use at a moment's notice. I recommend to follow the daily schedule of watching the videos, taking the daily quiz and then re-watching the previous videos and rereading your notes completely, daily. The class builds on itself and what doesn't make sense on day two will make sense on day four. Most students who pass the first time report having studied at least an hour and a half a day for five days and then a few hours the day before taking the actual test.
How long can I access my class?
The class is structured to be completed in five days. However(!), we know life happens so we give you access to your classes for two full weeks. This is ample time for you to prepare for the test, way more than necessary. We don't recommend taking longer because that's how procrastination happens. If you really need more time just let us know.
Am I guaranteed to pass the test?
Trade Masters Online guarantees all the information you need to pass the EPA 608 Universal test is contained in this class, but you are the only one that can take the test. Many students pass the EPA 608 weekly through this course. Remember, if you have any questions during your enrollment you have direct access to the instructor.

*This course is a prep class and prepares you in every possible way to pass the exam. Only you are responsible for your actual test scores. Reattempts are available for purchase.
