Heating, ventilation, and air conditioning (HVAC) keeps homes, hospitals, schools, data centers, and other businesses safe, monitoring air quality, and comfortable, monitoring temperature quality, year-round. That’s important work, and the people who install and fix those systems are in steady demand.
Becoming an HVAC technician is a career you can enter without a four-year degree, start earning a salary quickly, and grow in your career for decades. If you’re considering this career path, we have compiled some frequently asked questions (FAQs) to help you make an informed decision that’s right for you.
What does an HVAC technician do?
HVAC technicians install, maintain, and repair heating, cooling, ventilation, and refrigeration systems. On any given day, that might mean:
- Wiring a new furnace
- Charging an air conditioner with refrigerant or checking refrigeration levels
- Diagnosing a faulty thermostat
- Replacing a compressor
- Running seasonal maintenance to keep equipment efficient and safe
- Installing, maintaining, and repairing HVACR systems
- Inspecting and testing HVACR systems and components
- Cleaning air ducts and replacing filters
- Documenting maintenance activities
- Providing updates on system malfunctions and recommending mitigation and remediation strategies
- Making recommendations to improve system performance
The job combines multiple hard and soft skills, including:
- Knowledge of HVAC systems as well as plumbing and electrical concepts
- Problem solving ability
- Mechanical aptitude
- Physical stamina
- The ability to read blueprints and wiring diagrams so you can work with electrical and mechanical systems
- Experience (or knowledge of) using power tools
- Communication and customer service
- Time management and organization
The good news is that these skills can be developed over time. You don’t need to be an expert on day one.
How much do HVAC technicians make?
According to the U.S. Bureau of Labor Statistics (BLS), heating, air conditioning, and refrigeration mechanics and installers earn a median annual wage of $59,810. The highest-paid 10% earn more than $91,020. According to Payscale, the hourly wage for an HVAC technician can range between $19-$38, which equates to approximately $39,520 to $79,040 annually (based on hourly rate for 40 hours a week and 52 weeks a year).
According to World Population Review, HVAC Technicians in California can expect to earn approximately $53,100 for entry-level roles. As they gain experience, so will their earning potential:
- 2-4 years: $64,200
- 4-6 years: $71,900
- 7+ years: $96,400
This same trend can be seen across other states as well.
Additionally, adding certifications and specializing in areas such as commercial refrigeration or energy efficiency can increase your earning potential. According to BDR, certain certifications can increase your annual salary by anywhere from $3,000 - $8,000, while adding multiple certifications can increase it by $10,000 - $15,000.
Your specific take-home pay depends on where you live, where you work, and whether you do commercial or residential work. Many technicians also earn overtime during peak heating and cooling seasons when demand for repairs spikes.
Another major factor in how much you make is whether you own your own business. Starting your own company involves more risk than being an employee, but if you’re willing to put in the work and be patient, it can pay off. According to ZipRecruiter, the average HVAC company owner makes $86,147 annually (with salaries as high as $295,000).
Where do HVAC technicians work?
Some HVAC technicians focus on residential service calls. Others work on large commercial (e.g., schools, restaurants, office buildings) or industrial (e.g., manufacturing facility) locations. Depending on the type of work you do (i.e., residential, commercial, industrial), you may visit multiple homes or jobsites throughout a workday. The more complicated the job, the longer an HVAC technician might spend at one site.
Is HVAC a growing field?
Yes, and faster than most. The BLS projects employment of HVAC technicians and installers to grow 8% from 2024 to 2034 (much faster than the average for all occupations) with about 40,100 openings each year over the decade.
Several forces are driving that demand, including:
- New residential and commercial construction, requiring new HVAC system installation
- Aging HVAC equipment, requiring servicing or replacement.
- Energy efficiency upgrades
- A steady wave of retirements, creating new opportunities for the next generation of HVAC technicians
Just as important: HVAC work cannot be outsourced or done remotely. Someone must be on-site to assess, install, and maintain these systems. While evolving technologies like AI are changing the way many traditional office jobs are conducted, HVAC is an essential service that still needs to be performed by a live person, and those systems aren’t going away.
How long does it take to become an HVAC technician?
It depends on the path you choose. Here’s a breakdown of the three most common training pathways for HVAC technicians:
| HVAC certificate |
HVAC associate degree |
HVAC apprenticeship |
Typical duration: 6 to 15 months, depending on the program.
U.S. Career Institute’s HVAC certificate program can be completed in 3 to 5 months, on average.
Why choose a certificate program?
Gain the knowledge and skills necessary to not only pursue industry certification (e.g., EPA 608) but also pursue an entry-level role or apprenticeship to acquire hands-on training and experience.
|
Typical duration: 2 years
Why choose a degree program?
Build foundational knowledge of electrical systems, refrigeration, airflow, and safety. You may also be exposed to business courses which may be helpful if/when you choose to start your own business.
|
Typical duration: 3 to 5 years
Why choose an apprenticeship?
Learn while you work under the supervision of a licensed HVAC professional. Although an apprenticeship is not legally required, it is often recommended and preferred by employers to support hands-on learning. Some HVAC technicians choose to go straight into an apprenticeship, while others choose to complete a training program first to give them greater confidence and a solid foundation.

A common and efficient route is to complete a training program first and then step into an apprenticeship or entry-level role, where your coursework helps you advance faster and earn more sooner than someone starting with no background at all. In most cases, a high school diploma or equivalent will be required to move forward with a training program or apprenticeship.
Do I need a license or certification?
Many states and local jurisdictions require HVAC technicians or contractors to hold a license, typically after documented work experience and a passing exam. Additionally, virtually all HVAC technicians are required to hold a Section 608 Technician Certification, which the U.S. Environmental Protection Agency (EPA) requires for anyone who handles refrigerants.
Because the rules differ from place to place (and change over time), be sure to confirm the specific requirements with your state or local licensing authority before you begin working independently.
Can I train for HVAC online?
Yes! You can build your foundational knowledge online. For example, U.S. Career Institute offers a 100% online, self-paced HVAC certificate program that covers the core concepts you’ll need in your new HVAC career, including:
- Safety standards and requirements
- HVACR materials, equipment, and tools
- Refrigeration cycle, gas laws, and properties of refrigerants required for diagnostic and systems design
- Evaluation and installation processes for electrical systems and controls
- Procedures for installing, inspection, testing, repairing, and maintaining HVACR systems
Government regulations regarding conservation, recovery, and recycling of refrigerants
Because HVAC is a hands-on trade, you’ll still need practical, in-person experience through an apprenticeship or employer to become fully job-ready. That said, online coursework is a strong, affordable way to get started. The right online program helps you understand the fundamentals before you ever pick up a tool and will help you stand out when you apply for an apprenticeship or entry-level position.
How do HVAC technicians advance?
The HVAC industry offers a clear and attainable ladder for success. Some technicians start as entry-level service technicians then move up to lead technicians as they earn certifications and prove themselves on harder jobs. From there, paths can branch out. You can specialize in areas like commercial refrigeration or building automation, move into roles like service manager or estimator, earn a contractor or master license, or start your own HVAC business. Because the trade rewards skill and results, motivated technicians can advance steadily throughout their career.
Is HVAC a good career, and how do I get started?
For the right person, it is a strong choice. Not only can you start this new career quickly, but the pay is competitive and grows as you gain experience or specialization. You may even choose to start your own business, which creates even more opportunity and earning potential. The demand for qualified HVAC technicians is projected to remain strong over the next decade, which is great news for new HVAC technicians.
If you like solving real problems and want to build a valuable skill set in a stable career field, becoming an HVAC technician is worth a serious look.
