Training

• Learn HVAC fundamentals, including how to read blueprints, electrical schematics and specification documents. You'll also need to learn how to install a variety of systems from scratch, including gas, electric and oil units.
  
  The typical training program also includes instruction in multiple-fuel heating units and air conditioning systems. As a well-trained technician, you must also be versed in the design and installation of heating ducts, fuel and water lines, vents, pumps and other elements associated with heating, ventilation and air conditioning.
  
  Once these items are in place, you may be required to wire the systems as well as any various control and ancillary components. Next, you will be required to test the system to ensure the proper operation. You will also learn the basics of the installation and repair of residential, commercial and industrial refrigerants and air conditioning units.
  
  The training curriculum should also help you gain knowledge of AC components and the workings of a vapor compression system. You will develop the skill set to work with air conditioning piping, compressors, the compression cycle and how to use refrigerant tables and properties.
  
  

Training Programs

• If you are still in high school, work on developing solid reading and math skills. Generally, you must be a high school graduate, or have a GED, to register in a HVAC technician training program. Check with local trade schools, community colleges and vocational institution regarding HVAC training programs. There are also online schools that offer diploma and certificate programs in HVAC technician education. Many people receive training through apprenticeship programs operated by trade unions.
  
  Some training programs can be completed in as little as nine months. Apprenticeship programs can take as long as three to five years. Before you choose a school, verify that the training program is credentialed by the Accrediting Commission of Career Schools and Colleges of Technology. Check with the state licensing agency to ensure the school meets the state's requirements.
  
  When you graduate from a HVAC training program, you should have a firm foundation and understanding of all types of HVAC systems. Not only should you gain exposure to conventional and unconventional HVAC schemes, but how to design, operate and install HVAC units.
  
  

Considerations

• The requirement for working as a HVAC technician is decided by each state. Besides making sure that the training program you complete is acceptable in your state, you may also have to meet specific licensing stipulations.
