This training program is geared towards giving individuals basic technical knowledge of refrigeration Systems to teach them the preventive maintenance skills and repair skills needed when seeking employment in this industry. Due to the pressures of servicing advanced equipment and satisfying demanding customers, continuing education is mandatory for succeeding in today’s industry. Consumers want quality, yet are increasingly cost-conscious. They demand excellent service, competitive prices, and want to know exactly what it will take to get the job done effectively and efficiently. WHAT LEARN A TRADE PROVIDES • Training to reduce callbacks • Training to improve diagnostic and troubleshooting skills • Tips for working and communicating with customers and the general public • Action plans to improve efficiency • Safety guidelines • Basic and advanced levels of training LEARN A TRADE is one of the Environmental Protection Agency programs. Our materials have been used to certify technicians in accordance with Section 608 of the U.S. Clean Air Act. Who needs to be certified? Since November 14, 1994, the sale of all CFC and HCFC refrigerant has been restricted to technicians certified through an EPA-approved certifying organization. Any person who performs maintenance, service, repair, or disposal that could reasonably be expected to release refrigerants into the atmosphere must be certified. Note: Apprentices are exempt from certification requirements provided the apprentice is closely and continually supervised by a certified technician. The definition of “technician” specifically includes the following activities: attaching and detaching hoses and gauges to and from the appliance to measure pressure within the appliance adding refrigerant to or removing refrigerant from the appliance any other activity that violates the integrity of MVAC-like appliances and small appliances. Invest in yourself and your future through certification! Being certified signifies that you have the technical skills and knowledge and have met the necessary requirements to install and service today’s complex HVACR systems effectively. Whether you need EPA Section 608, NATE, or R-410A certification, being certified proves your competency to your employers and your customers. Certification highlights your area of expertise and shows that you have the training needed to provide quality, professional service. Through certification you will become a more valuable asset to your employer and your customer. Although most certification is voluntary, it will give you a competitive edge. By obtaining certification and achieving a higher standard of job performance, you will position yourself to move ahead in the industry. If you need a structured exam preparation program to help you master the skills and material that most often appear on HVACR industry certification exams, consider using the LEARN A TRADE training materials. What does the exam consist of? The EPA Section 608 certification exam is made up of 100 multiple-choice questions. Each set of 25 questions is a “section” for a specific “Type” of certification, as follows: Core (Questions 1–25). A Technician must pass Core in order to earn any other certification. Type I (Questions 26–50). For servicing small appliances. Type II (Questions 51–75). For servicing or disposing of high-pressure appliances, except small appliances and MVACs. Type III (Questions 76–100). For servicing or disposing of low-pressure appliances. Universal. The successful passing of all four sections of the exam. A passing score of 70% or better is required in each section to pass. The exam is a closed-book test. Where can I take the exam? EPA certification testing is conducted by LEARN A TRADE an approved proctor at various locations throughout the year.
