HVAC stands for heating, ventilations, and air conditioning. HVAC technicians are professionally trained to install and configure new HVAC systems and provide services and support for older heating, ventilation, and air conditioning units. They usually need to be knowledgeable in the area of electrical and mechanical components of heating, ventilation, and air conditioning equipment. There are multiple paths to passing the HVAC technician certification exam, and although it may not be a requirement in all areas, it may increase the chances of getting a job or being paid a higher wage.
Being an HVAC engineer or worker does not have official educational requirements. Many HVAC technicians receive their training through coursework at a community college or a technical school, while others simply receive on-the-job training. Some technicians received apprentice work as their form of training. Since there are many companies which will not recognize or hire a professional HVAC technician without proper certification, it is required by law in some areas. This certification is normally available to those who pass a HVAC technician certification exam, and passing the test usually requires proper education and/or a year or more of experience.
Learning mechanical and electrical application skills for both residential and commercial facilities is generally the aim of HVAC training. To further the education and training, the maintenance of electrical, gas, and oil furnaces and air conditioning units is normally also taught. Overall installation, repair, and upkeep of units, which may be modern or outdated, is commonly required.
Other more specific areas of training include configuring calculations for heating and cooling systems, piping techniques, and industrial hazard safety skills. Many times, general education classes are not required, but basic mathematical skills and the ability to read industrial blueprints are helpful traits. When studying for an HVAC technician certification exam, it is better to assume these types of questions will be covered and be prepared for them. It may also help to understand some of the laws which apply to HVAC in your area of practice.
Many states and regions around the world now require that HVAC workers pass the HVAC technician certification exam and obtain proper licensing before they are allowed to legally work in the field. If classroom training was not obtained, there are typically study guides available from many publishers. These cover more specifically what is normally on the certification exam. Certification options are available through a number of organizations that acknowledge training and education in the HVAC industry.
