What Are EPA Type 1 and Type 2 Certifications?

EPA has developed four types of certification: For servicing small appliances (Type I). For servicing or disposing of high- or very high-pressure appliances, except small appliances and MVACs (Type II). For servicing or disposing of low-pressure appliances (Type III).

EPA Type 1 and 2 Certification is a program offered by the Environmental Protection Agency (EPA) to certify individuals to work on small appliances, air conditioners, and other refrigeration equipment. The certification is designed to ensure that individuals working in this field are knowledgeable in the safe handling and disposal of refrigerants and other hazardous materials. It is an important step to ensuring that both the environment and the health and safety of individuals are being properly protected. In this blog post, we will discuss what the EPA Type 1 and 2 Certification is, why it is important, and how individuals can obtain the certification. We will also explore the different levels of certification, the types of equipment the certification is applicable to, and the requirements for each level of certification. By the end of this post, you will have a comprehensive understanding of EPA Type 1 and 2 Certification and what is required to become certified.

Benefits of EPA certification

Here are several benefits of gaining EPA certification:

What are EPA certifications?

Heating, Ventilation, and Air Conditioning (HVAC) professionals can earn certifications from the Environmental Protection Agency (EPA). HVAC technicians must be certified by the EPA to handle any equipment that might leak refrigerant, a chemical that contaminates the air, harms the environment, and harms anyone who breathes it in.

The EPA certifies people by instructing them in safe handling procedures for equipment containing refrigerant, how to respond if they come into contact with it, and the dangers that could arise from releasing refrigerant into the atmosphere. Additionally, they learn how to care for, maintain, and discard appliances that contain refrigerants. All HVAC technicians are required by the EPA to be certified in order to carry out the following duties:

What is type 2 EPA certification?

You can handle medium-pressure and high-pressure appliances, which are those that contain up to 200 pounds of refrigerant, if you have Type 2 EPA certification. Because there are more refrigerants in these appliances, this certification focuses primarily on leak detection because a leak could seriously harm the environment. Those who hold this certification are able to spot potential leaks and fix any problems that could expose them to refrigerant.

What is type 1 EPA certification?

Any manufactured appliance with less than five pounds of refrigerant inside of it requires Type 1 EPA certification before a person can work on it. This certification teaches you how to set up and maintain small appliances, as well as the rules for handling their refrigerant. Individuals obtaining type 1 certification must be aware of the various requirements for handling small appliances manufactured before and after 1993 due to national manufacturing changes that took place for all small appliances in that year.

How to get EPA certification

Follow these steps to get EPA certification:

1. Decide on which certification is right for you

Choosing which certification is best for you is the first step in obtaining your EPA certification. You can decide this by assessing your experience and skill set. If you are a beginning HVAC technician, getting the type 1 certification and gaining experience with small appliances may be helpful before switching to high pressure equipment. Obtaining the type 2 certification may help you find more job opportunities and advance in your career if you have experience in the HVAC industry.

2. Complete a certification course

The EPA mandates that you complete a certification course, which is available online or in person, once you’ve decided which certification to obtain. The course covers the negative effects that refrigerants have on the environment, how to spot leaks, the distinction between low- and high-pressure appliances, the types of refrigerants, the dangers of exposure to refrigerants, and personal protective equipment. The type 1 and type 2 courses each have specialized material pertaining to details about the appliances you are permitted to use under each certification.

Search online for a facility that might offer one to find a certification course. Usually, EPA certification courses with an exam are offered by trade schools, career centers, and community colleges.

3. Take the certification exam

Passing the necessary certification exam is the last requirement for EPA certification. To become certified, you must pass two of the four exams the EPA offers. Each exam has 25 multiple-choice questions. All participants should be familiar with the fundamental HVAC concepts covered in the first exam, known as core, which includes topics like how to use personal protective equipment and how to contain a simple leak. Each exam requires specialized knowledge of particular appliances and refrigerants. Here is a breakdown of the different exams:

4. Stay up-to-date

Once certified, it’s important to stay informed of any changes to the EPA’s refrigerant regulations. You do not need to renew your EPA certification credentials because they never expire. This means that it’s critical for you to regularly review the EPA’s regulations to find updates on refrigerant handling, such as new refrigerant research or creative methods for handling appliances.

Tips for EPA certification

You can use the following advice to get EPA certification:


In order to be well-prepared for your EPA certification exam, it is helpful to study. It’s important to prepare and become familiar with the exam content because some facilities require you to wait a certain amount of time before retaking the certification exam if you don’t pass. Use online tools like study guides, practice questions, and tutoring to achieve this. Limit distractions so that you can concentrate on the study materials. For example, turn off your phone and put on noise-cancelling headphones.

Observe other HVAC technicians

It might be helpful to observe HVAC technicians who have EPA certification prior to taking your test. In addition to observing how they handle appliances containing refrigerant, you can question them about their certification exam experience. They could provide you with insightful guidance and practical advice as you study for the test.

Take practice tests

Try completing a few practice tests prior to the EPA certification exam to better prepare yourself. These tests contain questions that are comparable to those on the exam, giving you a good idea of the exam’s content. Record the questions you answered correctly and incorrectly after finishing a practice test so you can see where you need to improve. For instance, if you didn’t get the answers to several questions about finding leaks, you know you need to spend more time learning how to find refrigerant leaks.

Keep track of your certification card

A certification card that displays your credentials is given to you by the organization where you took the exam once you have attained certification. Employers might ask to see your certification card as proof. Keep track of where your certification card is at all times because if you misplace it, the organization might require you to retake the certification exam and obtain a new card.

What is a EPA Type 1?

Type II – High-Pressure Appliances With the exception of applications like small appliances or air conditioners inside of motor vehicles, this EPA certification will allow you to service or dispose of medium to very high-pressure appliances.

What is EPA Type 3 certification?

Any manufactured appliance with less than five pounds of refrigerant inside of it requires Type 1 EPA certification before a person can work on it.

What does it mean to be EPA certified?

EPA Type 3 covers low-pressure appliances. Any Type 3 or Universal technician who works on a Type 3 appliance must be certified. Remember that the EPA Type 1 covers small appliances like portable air conditioners and refrigerators?
