Refrigerator engineers work with heating, ventilation, air conditioning and refrigeration systems. All of these systems are important in the regulation of temperature and humidity in commercial and residential buildings and allow the transport and refrigeration of medicines and food. To become a refrigerator engineer, most employers require certain training and qualifications; however, some companies do offer on-the-job training and apprenticeships.

  1. 1

    Sign up for a technical training course specifically for this role at your local community college. Such post-secondary courses take between six months and two years to finish.

  2. 2

    Take classes in shop math, technical drawing, electronics, physics, chemistry, computer applications and blue print reading if you are a high school student interested in pursuing this as a career. These classes will provide you with a solid foundation for further study.

  3. 3

    Complete the programs at one of the three accrediting agencies for the industry: HVAC Excellence, the Partnership for Air-Conditioning, Heating and Refrigeration Accreditation, and the National Center for Construction Education and Research. Once accredited, you will be expected to gain at least six months to two years of work experience. After this point, you would generally be considered to be qualified as a refrigeration engineer.

  4. 4

    Another option is applying for an apprenticeship if you have a high school diploma. The apprenticeships can last anywhere from three to five years and combine paid, on-the-job training with classroom lessons and lectures. The apprenticeships can lead the way to accreditation.

  5. 5

    Get a license if it is required in your state. If your state requires you to apply for a license, you will have to pass a written test before qualifying for one.

  6. 6

    Get certified by passing the exams relevant to the type of refrigerants you will be working with. For example, small appliances, high-pressure refrigerants and low-pressure refrigerants all require specific exams to be passed in order for you to be certified to purchase and work with them.

  7. 7

    Further certification (and higher wages) can be gained by taking additional exams with various institutions. For example, The Air Conditioning, Heating, and Refrigeration Institute offers an Industry Competency Exam, which would provide you with another certificate relevant to the industry leading to opportunities for further advancement.

  8. 8

    According to the Bureau of Labor statistics, any courses that improve your competency with computer systems used in the industry would also be beneficial due to the increasing complexity of computer-controlled refrigeration systems.
