- EPA Type III Certification – This certification is specifically for work carried out while servicing and repairing low pressure systems
It must be remembered that requirements can differ from state to state for HVAC certification. There is one certification that is accepted in every state and this is referred to as the EPA HVAC certification. It is important to understand that the Environmental Protection Agency (EPA) has passed a refrigerant gas (R22 or R410A) must have EPA HVAC certification.
It is part of an HVAC Technician’s daily work routine to come into contact with these gasses on a regular basis while installing new units, repairing them or even carrying out routine maintenance. As a result, it is compulsory for a technician to have EPA HVAC certification. Today there are 4 different types certifications that apply to Section 608 and to qualify for each one you must pass an exam. The 4 different options are:
1) EPA Type I Certification
This certification is specifically for work carried out while servicing and repairing small appliances. You take this certification if you only ever work on small refrigerant units. When taking this course, you will learn about and take exams on the following areas:
- What is classified as a small appliance and what units usually have less than 5 kg of gas in them – A good example of this maybe an air conditioning unit for a small window.
- What are the correct tools and equipment to drain gas from a system
- What are the correct and safe working practices in order to recover the gas from various systems that may have a compressor and those systems that do not
- Learn about all of the different safety requirements that apply to the safe handling and removal of refrigerants.
To gain this HVAC certification you will have to sit and pass exams.
2) EPA Type II Certification
This certification is specifically for work carried out while servicing and repairing high-pressure systems. To get your EPA Type II Certification follows a similar path to that of the EPA Type 1 certification. You will do course work and then have to pass an exam. Some of the areas that you will study are:
- All about high-pressure refrigeration and gases
- How to detect leaks in high-pressure units
- Reasons to test for a leak before recharging or repairing HVAC system
- The requirements for repairing a refrigerant system that weighs over 50 pound
- Appropriate practice and recovery methods
- Prerequisites for disposal and major repairs
After taking the course, get ready for a certification test. It is recommended to attend a normal class rather than self-studying or distance learning. But it depends on how fast you need the certificate as well as the amount of time you have for the course.
3) EPA Type III Certification
This certification is specifically for work carried out while servicing and repairing low pressure systems. This certification relates to servicing low-pressure systems. It entails the same subjects as in Type 2 EPA course except the details are for low-pressure units. The course enables HVAC technicians to refresh their theoretical know-how, and a major advantage is those technicians who already have practical experience in the field of work.
4) Universal EPA Certificate
This certificate is granted once you have studied the content of the above 3 courses. With a universal certificate, you can handle any HVAC system. This certification comes in handy when you start job-hunting as you will be well qualified as you are able to work on all types of HVAC units. While it may take more time and effort to complete the course, it is the type of certificate you need to work in any state. However, even though you hold this certification you must also be sure to comply with the other local state laws and regulations pertaining to the licensing of HVAC professionals.
5) North American Technician Excellence (NATE)
The North American Technician Excellence (often referred to as NATE) is anon-profit organization that offers accredited programs and certificates to HVAC professionals. Not every HVAC professional holds a certificate from this body but is recommended for good reasons. NATE is more geared towards the practical aspect of HVAC, making it the perfect place to validate HVAC knowledge and skills. NATE follows a very thorough process when it comes to certification. They understand that newly qualified HVAC technicians have different needs than the experienced ones and so varied exams are offered according to the level of experience working on gas furnaces, air conditioning units and also air distribution units.
Another thing that distinguishes NATE from the rest is that the exams are split into various specialties e.g. gas furnaces, air distribution, air conditioning, heating and cooling, and so on. Check out the 2 levels of certification offered at NATE:
- Entry level
This is a certification for workers who are starting out in the HVAC industry and want to make it their career. It is meant for technicians who are new to this industry and looking forward to gaining practical experience. To obtain the NATE entry-level certificate, you must pass two types of exams namely:
- Ready to work test: it is ideal for novices who haven’t undergone formal training or are without a solid educational background. The main aim of the exam is to determine how well a candidate understands the basics that include heat transfer, safety measures, the use of HVAC tools and equipment, and general electrical knowledge. There are fifty questions to be covered in the exam. A candidate is offered a certificate upon attaining a PASS mark.
- HVAC support technician exam: this exam is for candidates who have a field experience of between 6 and 12 months. It encompasses advanced topics, which are not covered in the ready-to-work test such as system components, installations, design factors, and planned maintenance. It is a 100-question exam that requires you to get a PASS mark to get the certificate.
- Professional Level
Technicians with field experience of more than 12 months are supposed to get a professional level certificate from NATE. Again, the certificate is divided into a number of specialties as listed below:
- GS- Gas heating
- AC- Air conditioning
- OL- Oil heating
- HO- Hydronics oil
- AD-Air distribution
- RC-Commercial refrigeration
- HP- Heat pumps
- EA- HVAC Efficiency analysis
- HG- Hydronics Gas
- LC- Light commercial refrigeration

Become Self Employed as a HVAC Certified Contractor
If you have ever wanted to be self-employed, working by yourself or with employees, you should explore the idea of getting HVAC technician certification.
Regulations currently vary from state to state with the majority of states making it compulsory to hold a HVAC license. It is possible to supervise your workers while they are carrying out work or repairs on HVAC systems. However, some states may require you to have an employee working for you who is classed as a “qualifier”. This is an employee who has already passed their exams and is state licensed and qualified to carry out this work. If the “qualifier” who works for you has the correct license and all their paper work is valid, the contractor is able to carry out HVAC work in that state as long as the “qualifier” is there to supervise the HVAC work.
A contractor must also demonstrate that they are knowledgeable in the different aspects of business law that applies to their state in addition to being certified as a HVAC technician. When you are a self-employed contractor you will not only have to carry out the various repairs and installation work associated with the HVAC industry, but will also be responsible for the general day to day running of the business. This will include understanding current labor regulations, paying state and government taxes, as well as having the correct business licenses.
Requirements will vary from state to state but generally you will need a business exam in addition to the HVAC knowledge exam, in order to get HVAC certification.
