While a technician may opt for training through a certified program, he or she may also chose to be trained by a journeyman.

People who pick up the trade by those means are apprentices of the journeyman, and they are exempt from the EPA certification requirements as they are working under the watchful eye of the certified technician.


Once your HVAC/R training has been completed and you have graduated your education is far from finished.

You must stay on top of environmental protection laws and state and federal regulations.

Therefore, you need to develop as a technician and be meticulous with your record keeping.

These records log your work with refrigerants, which can be bought only by certified technicians.

As a HVAC/R technician you must be ready to learn continually.

There will be technology upgrades and changes, as well as frequent amendments to codes and regulations.

All of that requires you to take classes and learn constantly in order to know how to service and install new equipment; and keep your license.


HVAC technicians with their own businesses need to be licensed by the Arizona Registrar of Contractors.

This license is a specialty commercial license.

There are two licenses that you can acquire according to the classification requirements you meet.

There is a CR-39 specialty license for Air Conditioning, Refrigeration and Heating, and a CR-79 specialty license Air Conditioning and Refrigeration Including Solar.

To acquire a license you must have four years of experience, pass a business management exam, and an Air conditioning and Refrigeration Trade Exam.

If you want to work with solar units as well, then you need to pass the Solar Exam along with the previously listed exams.

Technicians with their own businesses must pass the additional Contractor License Exam.

Examination Process

Apart from EPA Certificate that technicians attain by passing a written exam, there are additional tests that must be passed so as to acquire a license.

EPA Certification

Under the EPA Section 608, each HVAC technician must have an EPA certificate.

The certificate can be attained by passing an EPA-approved test, and it does not have a date of validity as it does not expire.

There are four types of certification.

Type I allows you to work with small appliances, type II with high-pressure appliances, and with type III certification you are allowed to work with low-pressure appliances.

In case you want to be able to service all equipment types, then you need to have the Universal Certification.

Additionally, the Universal Technical Institute in Scottsdale and The Refrigeration School, Inc. in Phoenix can give you on-site training that you would need for certification.

Contractor License Examinations

The PSI Exams can be either computer-based or written, and administered by the Arizona Registrar of Contractors.

In order to be an eligible candidate for taking the exam you must pay the exam fees in advance, as well as register online.

The exam sites are in Flagstaff, Glendale, Phoenix, Scottsdale, Tempe, Tucson, and Yuma.

In case you have taken the computer-based test, your test score will appear on screen upon finishing the exam.

That means that you will know whether you have passed the test or not immediately.

However, if you opt for the written exam, you can only get the unofficial score report after the test.

You may get all the necessary information about the exam, as well as the registration form here.

The Arizona edition of the NASCLA Contractors Guide to Business, Law and Project Management can be bought at the PSI Online Store.

There are two parts to the Trade Exam. Each candidate has 210 minutes at their disposal for The AZ R-39/C-79 Air Conditioning and Refrigeration (Residential/Commercial) exam.
