Complete your high school or GED program. Classes in shop math, applied physics and chemistry and computer applications are all beneficial courses if you intend to train in HVAC. Since this trade is becoming more technical, having at least a basic knowledge of electronics and plumbing is helpful.
Locate an accredited training program in your area. Three agencies set the academic standards for HVAC training programs: HVAC Excellence, the National Center for Construction Education and Research and the Partnership for Air-Conditioning, Heating, and Refrigeration Accreditation. Check that the program has received the proper accreditation.
Enroll in a HVAC training program. Post-secondary and trade schools both offer students the possibility of training to service HVAC systems.
Complete the required training as per your course schedule. Courses in a HVAC training program involve both classroom and hands-on training that allow students to become proficient with the different systems involved.
Gain field experience. It will take between six months and two years for a newly trained HVAC technician to be considered proficient at his trade. Until reaching proficiency, HVAC technicians are unable to work alone.
Pass state and local licensing and certification tests after completing two to five years of job experience. The content of the tests vary among states, but proper licensing and certification are required to purchase or handle refrigerant products.
Apply to an apprenticeship program in place of a HVAC training program. The Air-Conditioning Contractors of America and other similar institutions run apprenticeship programs. Applicants to apprenticeship programs, like those attending training programs, require a high school diploma or GED.
Train on-the-job at servicing air conditioning systems. Apprenticeship programs last between three and five years, during which time you are paid for your work. Since your initial experience is limited, you begin your on-the-job training completing more menial tasks, such as transporting materials and insulating refrigerant lines. As you gain experience, your tasks become more complex.
Attend classes when not at work. These classes combine learning the technical aspects of air conditioning systems with a knowledge of the legislation and regulation concerning refrigerant products.
Complete the apprenticeship program. Pass the licensing and certification tests required by the state.
