CFC Certification

In 1992 The Environmental Protection Agency (EPA) mandated mandatory certification for a national recycling and emissions reduction program in the stationary air conditioning and refrigeration industry.

Our certification test was developed by VGI Training and is EPA approved. The course manual includes all of the information needed to refresh technicians on how to recover and contain refrigerant from both high- and low-pressure air conditioning and refrigeration equipment above and/or below 25 tons.

Upon passing the certification test, the technician will receive a certificate and a wallet card from VGI Training. In addition, VGI Training will maintain a database of all technicians who have successfully passed the VGI Training Refrigerant Recovery test.

NOTE: The refresher course is not a training process. Those taking the certification test should have a basic and working knowledge of HVAC equipment, installing and/or servicing, and prior related theory instruction (at least 240 hours).

    NATE Certification

    North American Technician Excellence (NATE) is the leading certification program for technicians in the heating ventilation, and air conditioning (HVAC) industry.

    The Core Exam covers safety, tools, soft skills, principles of heat transfer, total comfort, and electrical.  An HVAC technician must pass the Core Exam and at least one of the Specialty Exams to become a Certified Technician.

    There are five separate Specialty Exams - air conditioning, air distribution, gas heating, heat pumps, and oil heating.  There are two types: installation and service (service technicians are automatically certified as installation technicians, as well).

    The Core Exam consists of 50 questions and each Specialty Exam consists of 100 questions.  Test timing for the Core Exam and one Specialty Exam is a maximum of 4 hours.
