This page answers some frequently asked questions about becoming an HVAC technician, what to look for in an HVAC school, and more.

What HVAC Technicians Do

What are the duties of an HVAC technician?

HVAC technicians install, inspect and maintain heating and cooling systems in buildings. They work to keep HVAC systems operating safely and efficiently.

Specifically, HVAC technicians may:

Where do HVAC technicians work?

HVAC technicians work in a wide range of settings because every building needs an HVACR system. Work sites for HVAC technicians include factories, homes, schools, hospitals, construction sites, and much more. According to the U.S. Bureau of Labor Statistics (BLS), the most common employers for HVACR technicians in May 2019 were:

Are there many women working in HVAC?

As with other skilled trades, there is a definite gender imbalance in HVACR. BLS labor force statistics for 2020 indicate that only 1.5% of people working in the field were women.[2]

However, industry efforts to address this issue are growing. For example, Altierus Career College partners with Women in HVACR, a non-profit organization that aims to increase the number of women HVAC technicians through education, mentorship and networking opportunities.

How to Become an HVAC Technician

What do you need to know before starting HVAC school?

To apply to our HVAC technician program, you need to be a high school graduate or hold a GED. There are no specific electives required. However, it’s worth mentioning that HVACR is a hands-on, physical job which can involve constant activity. You should have fine motor skills, be capable of crawling or climbing into tight places, and be able to lift or move moderate amounts of weight.

How long does it take to become an HVAC technician?

You can train to become an HVAC technician in a year or less. Our HVAC diploma program lasts nine months—or 12 months if you are pursuing HVACR training. This includes online coursework, in-person labs, and certification exam prep. Learn more in our article “How Do I Become an HVAC Technician?”

Can you become an HVAC technician without going to HVAC school?

HVACR systems have become so complex that most employers prefer to hire candidates with specific post-secondary education. This ensures they are hiring technicians who have a rounded understanding of different HVACR systems as well as crucial safety and environmental practices—understanding which is unlikely to be developed through on-the-job training alone. In addition, many states and localities are increasing regulation of HVACR workers through licensing programs.

For you, one of the many advantages of going to HVAC school is that you are able to learn and practice skills in a lab environment rather than on a job site. In addition, you will receive support preparing for certification exams instead of having to study by yourself.

Are there certification exams for HVAC technicians?

Yes. There are several HVAC certifications related to safe handling of refrigerants, and one related to general workplace safety.

The U.S. EPA regulates a number of toxic refrigerant chemicals under Sections 608 and 609 of the Clean Air Act. These refrigerants can cause harm to people and the environment if not handled properly. At Altierus Career College, we prepare students for EPA 608 Universal Certification, which applies to HVACR systems in buildings. (EPA 609 Certification applies to motor vehicle HVACR systems.)

The Esco Group provides certification for safe handling of some pressurized-gas refrigerants. We prepare our HVACR students for the Esco Group Universal R410A Safety and Training certification, which certifies them to handle one of the most common pressurized refrigerants.

In addition, we prepare our students for a basic occupational safety certification offered by the U.S. Occupational Health and Safety Administration (OSHA). We want our students to be familiar with practices and principles that can keep them and the people they work around safe.

As a certified technician, you can stand out more in the job market. Altierus Career College provides specific test prep during our HVAC program and also covers test fees for exams in tuition costs.

You can learn more about the importance of certification for HVACR technicians in our article, “Why Does HVAC Certification Matter?”

Why Go to HVAC School?

How much does an HVAC technician earn?

Nationwide, the BLS reports that the median annual salary for HVAC technicians was $50,590 in May 2019. The bottom 10% of HVAC techs earned less than $31,910, while the top 10% of earners made more than $80,820.[3]

Is going to HVAC school worth it?

Yes! If you love machinery and electronics and enjoy physical, detail-oriented work, you could make a great HVAC technician. You are also entering a stable career field. New buildings require HVAC systems, and older buildings need to be retrofitted with more energy-efficient ones. As a result, the BLS projects that demand for HVAC technicians should rise by 4% from 2019-2029, adding 15,100 new job openings across the country.[7]
