To become an HVAC technician, you usually complete an HVAC program at a technical school or community college, which BLS says lasts from 6 months to 2 years, or join an apprenticeship. You then need EPA Section 608 certification to handle refrigerants, plus any licence your state or locality requires, and a period of on-the-job training.
The EPA certification is the non-negotiable part. BLS says the EPA requires nearly all HVAC technicians to be certified in refrigerant handling, and the exam is usually built into a postsecondary HVAC program.
Here's the full route, with pay and outlook data from the US Bureau of Labor Statistics (BLS) and the certification rule from the EPA, read in October 2026.
HVAC technicians in numbers
| Measure | BLS figure |
|---|---|
| Median pay (May 2025) | $61,010 a year |
| Lowest 10% and highest 10% | Under $40,050 and over $95,210 |
| Jobs in 2025 | 440,900 |
| Projected growth 2025 to 2035 | 11%, much faster than average |
| Openings each year | About 40,600 on average |
| Typical entry-level education | Postsecondary nondegree award |
Those pay figures are as of October 2026. An 11% growth projection is one of the strongest of any skilled trade.
How to become an HVAC technician, step by step
- Take vocational education, math and physics in high school if you can. BLS recommends them.
- Enrol in an HVAC program at a technical school, trade school or community college. Programs last 6 months to 2 years and lead to a certificate or associate's degree.
- Or choose an apprenticeship. These usually last several years and combine paid on-the-job training with technical instruction in safety, blueprint reading and heating and cooling systems.
- Pass the EPA Section 608 exam. It's required for technicians who maintain, service, repair or dispose of equipment that could release ozone-depleting refrigerants.
- Check your state and local licensing rules. Some require a licence on top of the EPA certification.
- Start under an experienced technician. New hires begin with tasks like insulating refrigerant lines or cleaning furnaces, then move on to soldering pipes and checking circuits.
- Add manufacturer or industry certifications if your employer prefers them.
The insight: the EPA doesn't send you a card
This trips up a lot of new technicians. The EPA itself says it does not issue Section 608 certification cards. Your card comes from the certifying organisation that ran your exam, so if you lose it, you go back to that organisation, not the EPA. Keep a photo of your card and a note of who issued it. Employers will ask to see it, and so will refrigerant suppliers.
There's also manufacturer and industry certification on top. BLS says many of these are optional, though some employers prefer or require specific ones, and CareerOneStop lists what's available. Ask the companies you want to work for which ones they value before you spend time on any.
The rule sits in federal regulations (40 CFR Part 82, Subpart F) under Section 608 of the Clean Air Act, which is why it applies everywhere in the US regardless of your state's own licensing rules.
Where HVAC technicians earn the most
| Industry | Median pay (May 2025) |
|---|---|
| Wholesale trade | $71,190 |
| Retail trade | $62,830 |
| Educational services | $62,520 |
| Plumbing, heating and air-conditioning contractors | $60,030 |
Program or apprenticeship?
Both routes work, and they suit different people. A school program is faster: 6 months to 2 years, a certificate or associate's degree at the end, and the EPA exam usually included. An apprenticeship takes several years, but you're paid from the start and you learn on real jobs. If you can't afford to stop earning, an apprenticeship is the safer bet. If you want to get into the field quickly, a program gets you there sooner and you'll still do on-the-job training once you're hired.
Employers sometimes hire people with only a high school diploma, BLS says, so it's worth asking local contractors whether they'll train you. Either way, you'll start on basic tasks and build up, and you'll need a driver's license to get to jobsites.
What the job is like
HVAC technicians work in homes, schools, hospitals and other buildings, often travelling between service calls during the day. Some work outdoors in all weather, and many work in cramped spaces or in buildings that are uncomfortable precisely because the heating or cooling has failed.
BLS doesn't sugarcoat the risks: HVAC technicians have one of the highest rates of injuries and illnesses of all occupations, from burns to strains from heavy equipment. Refrigerants are hazardous, so protective gear and safe lifting technique matter. Most technicians work full time, with evening or weekend shifts, on-call work and overtime in peak heating and cooling seasons.
If you plan to run your own business later, look at HVAC software for scheduling and dispatch, and HVAC estimating software for faster quotes.

My verdict
If you want a trade with strong growth and a quick start, HVAC is hard to beat: a program can take as little as 6 months, and BLS expects about 40,600 openings a year. Get your EPA Section 608 certification as part of your training, check your state's licence rules, and keep your card safe. Expect physical, seasonal work, and expect to be busy.
Frequently asked questions
How long does it take to become an HVAC technician?
HVAC programs last from 6 months to 2 years, according to BLS. Apprenticeships usually take several years.
Do HVAC technicians need EPA certification?
Yes. The EPA requires technicians who maintain, service, repair or dispose of equipment that could release ozone-depleting refrigerants to be certified under Section 608.
Does the EPA issue the 608 card?
No. The EPA says it does not issue Section 608 certification cards. The certifying organisation does.
How much do HVAC technicians make?
BLS reports median pay of $61,010 a year in May 2025, as of October 2026.
Do HVAC technicians need a state licence?
Some states and localities require one on top of EPA certification. BLS says to check with your state and locality.
What does a new HVAC technician do?
New hires typically work alongside experienced technicians, starting with basic tasks such as insulating refrigerant lines or cleaning furnaces, then moving on to cutting and soldering pipes and checking electrical circuits.
Do HVAC technicians work in the summer and winter?
Yes, and peak seasons are the busiest. BLS says technicians may be on call and work overtime or irregular schedules during peak heating and cooling seasons.
Is HVAC a growing field?
Yes. BLS projects 11% growth from 2025 to 2035, much faster than average, with about 40,600 openings a year.
