For those who might not know, HVAC stands for heating, ventilation and air-conditioning. HVAC technicians and engineers are responsible for the installation and maintenance of any of these kinds of systems. There are a variety of different career options in the HVAC field and the requirements vary with each job. As HVAC jobs are expected to increase by 30% in the next seven years, there is a definite need for more people to join the job field.

Within the HVAC field, there are a wide range of jobs. You can pursue a career in HVAC sales, installation, design, maintenance or service. Some choose to specialize in a certain area while others work in the residential or commercial side and focus on installation and repair. You could design systems for new environmental areas, alternative energy systems or inspection services. In sales, you could be dealing with people in the field, working directly with contractors, or doing factory and consumer sales. The most populated job is as a HVAC technician, where you are usually dealing with repair and replacement on already existing systems.

To become an HVAC technician, you will need to have your high school diploma, and then either undergo an apprenticeship or a certification or training program. HVAC staffing companies are beginning to want more formal training from their prospective employees, so completing a certification or 2 year degree program will increase the chances of finding a good position. In some states, you will also be required to obtain a license. If you are looking at becoming an HVAC engineer, you will need a bachelor’s degree in either HVAC engineering technology, mechanical engineering, architectural engineering, or a similar field.

If you are considering delving into the world of HVAC, take into account that although your work is essentially to make people more comfortable in their home or office, you will most likely be feeling the opposite while working. You’ll frequently be in cramped spaces that are overly heated or chilly. Many systems and equipment are located in basements, on roofs, under houses, or inside of walls. You will be wearing safety equipment and hauling all of your tools around with you. Often times your hours are less than ideal as many businesses want to repair or remodel without closing. So you’ll be working late nights or early mornings, weekends or holidays. And don’t forget that some of the systems you need to reach are outside and open to the elements.

However, if you are strong and healthy enough to take on a job in HVAC, the rewards come in helping others, never panicking when your own air-conditioning breaks and a great average annual salary of over $42,000. There is also a lot of opportunity to open your own HVAC business once you have obtained the necessary knowledge and experience. And as the job outlook, according to the U.S. Bureau of Labor Statistics, is excellent, there’s no reason not to start now.
