What Is an HVAC Technician?
An HVAC-R technician ensures heating, ventilation, air conditioning and refrigeration systems function properly. They work in homes, schools, offices, factories, hospitals and other buildings. Some choose to specialize in one or more areas of HVAC-R, such as heating systems, commercial refrigeration, testing and balancing, or solar panels.1
When comparing an HVAC installer vs. HVAC technician, the two have slightly different roles. HVAC installers focus on installing HVAC systems and wiring, while an HVAC technician focuses more on the maintenance, repair and cleaning of HVAC systems. Some people compare HVAC installer vs. technician careers and choose to specialize in one. However, depending on your HVAC training and career path, your role may include a mix of installation and maintenance duties.
What Does an HVAC Technician Do?
Heating, air conditioning, and refrigeration mechanics and installers—often called HVACR technicians— work on heating, ventilation, cooling, and refrigeration systems. They may work in tight spaces and extremely hot or cold environments because of the broken heating or cooling systems they’re fixing.1 It’s also common for these technicians to work overtime or irregular hours during heating and cooling seasons, the Bureau of Labor Statistics (BLS) reports.2
- Install HVAC-R systems, wiring, and electrical elements
- Maintain HVAC-R systems
- Clean ducts, change filters, and refill refrigerant
- Repair or replace old or broken parts
- Test and inspect HVAC-R systems
- Check pipes for leaks
- Evaluate electrical parts of HVAC-R systems
- Maintain records of work performed
- Recommend maintenance efforts to better HVAC-R performance
- Sell maintenance service contracts to clients
- Follow refrigerant conservation and recycling regulations
HVAC-R technicians also troubleshoot repairs and maintain commercial refrigerators, freezers, and ice machines.
HVAC-R technicians may work with other individuals to install and maintain heating and cooling systems. Especially for large projects, they may work with sheet metal workers, electricians, boilermakers, and/or plumbers and pipefitters.3

How to Become an HVAC-R Technician
Though everyone’s career path looks a little different, below are four steps to become an HVAC technician.
- Obtain a high school diploma or equivalent. Earning a high school diploma or GED is the first step toward preparing for this career field. The BLS recommends taking high school courses in vocational training, physics, and math.7 Developing your knowledge of electrical work or plumbing is also beneficial for this career.
- Complete an HVAC-R program. Many people enroll in an HVAC technician training program through a college or trade school to learn the necessary heating, ventilation, AC, and refrigeration skills. These programs typically last six months to two years and lead to a certificate or associate degree.
- Gain training and experience. When you’re starting out, you’ll gain experience by working alongside experienced HVAC technicians. Some technicians gain experience through an apprenticeship program, the BLS notes.7 Either way, you’ll begin with simple tasks such as cleaning HVAC systems and move onto more difficult tasks such as checking electrical circuits in systems.
- Earn licenses and certifications as needed. Some states require HVAC-R technicians to be licensed. Check your state and local area’s requirements to see if you need to become licensed. According to the BLS, the U.S. Environmental Protection Agency (EPA) requires technicians who work with refrigerant-cooling systems to be certified in appropriate refrigerant handling (more on this below).7 If you’d like to, you can complete additional HVAC technician certifications.
Do I Need to Do an HVAC Apprenticeship?
No, you don’t need an apprenticeship—but you do need training and experience. Some people choose to complete an apprenticeship to gain the necessary HVAC training and experience. HVAC apprenticeships typically last three to five years and are sponsored by groups such as unions and contractor associations, the BLS reports.7
Do I Need to Join a Union to Work in HVAC?
No, you don’t need to join a union to work in HVAC. However, joining a union is an option. According to Union Plus, a non-profit committed to providing valuable benefits to union members, the main benefit of joining a union is having representation when it comes to your pay, hours, benefits and workplace safety.8 If you’re interested in joining an HVAC union, search for unions in your area.
Are There Any HVAC Certifications?
If you’re handling refrigerants, you’ll need to earn a Section 608 Technician Certification through the EPA. Which certification you earn depends on the type of work you plan to do. For example, the EPA offers four Section 608 Technician Certifications:9
- Type I: for working on small appliances
- Type II: for working on high-pressure and very high-pressure appliances
- Type III: for working on low-pressure appliances
- Universal: for working on all types of equipment; you have Type 1, Type II and Type III certifications
Other HVAC technician certifications you may consider are offered through the North American Technical Excellence (NATE) and ESCO Group’s HVAC Excellence.
NATE offers four HVAC technician certifications depending on how much experience you have:10
- Ready-to-Work Certificate
- HVAC Support Technician Certificate
- NATE Certification: Core & Specialty Tests
- Senior Level Efficiency Analyst Certification
Similarly, HVAC Excellence offers Employment Ready Certifications, Professional Level Technician Certifications and Master Specialist Certifications.11
What Skills Should I Have?
