An HVAC technician installs, repairs and maintains heating, ventilation, air conditioning and refrigeration systems. The work is hands-on and happens at customer sites, in homes, shops, offices and plants. It suits people who like fixing things, can read a wiring diagram, and are fine with driving between jobs, working in attics and on roofs, and talking to customers.

What employers ask for

Most technician postings ask for customer service skills, OSHA safety training and the ability to read electrical schematics. Many also ask for preventive maintenance experience. Most field postings mention a driving licence, and some ask for a clean driving record or a DOT medical card, which is needed to drive some commercial vehicles.

Postings labelled "entry level" are rare. Many postings do not state a level, so a junior candidate has to read the requirements, not the title. Field technician jobs are on-site; the few remote roles are not field work.

For a wider view of pay, the BLS reports a median of $61,010 a year ($29.33 an hour) in May 2025 (checked October 2026). The BLS counted 440,900 jobs in 2025 and projects 11% growth for 2025–35, with about 40,600 openings each year.

Employers include equipment rental companies, mechanical contractors, building services firms and HVAC equipment makers. Typical titles are "Commercial HVAC Service Technician", "HVAC Installer", "Master HVAC Technician" and "HVAC Team Lead".

Step-by-step: how to get in

1. Check your state and city rules first. The BLS notes that some states and cities require a licence. Rules differ a lot. Look up your state licensing board before you pay for any course. See the Texas example below.

1. Choose a training route. There are two main routes: - Trade school or community college. Programs last about 6 months to 2 years (BLS). Tuition differs by school, so ask each school for the full cost, including tools and exam fees. - Registered apprenticeship. You work for pay under a mentor, your wage rises as you progress, and you take classroom instruction. At the end you get a portable, nationally recognised credential (Apprenticeship.gov). The BLS says apprenticeships last several years. The big advantage is that you earn while you learn.

1. Get EPA Section 608 certification. Federal rules say technicians who service or dispose of equipment that could release refrigerants must be certified (EPA). There are four types (EPA): - Type I: small appliances - Type II: high-pressure equipment - Type III: low-pressure equipment - Universal: all of the above

The certificate does not expire. The exam is run by an EPA-approved certifying organisation. For Universal, the Core section must be taken as a proctored exam. An open-book Core result does not count toward Universal.

1. Take OSHA 10-hour training. OSHA safety is a common requirement in technician postings. The OSHA Outreach program is voluntary and is not a certification, but you get a completion card that you can show to employers. Some employers, states or cities require it.

1. Get or keep a clean driving record. Most field jobs include a company van. A lost licence can mean a lost job offer.

1. Register where your state requires it, and apply. In Texas, for example, you need a technician registration before you work (see below). Apply to postings that list a helper, apprentice or installer role, or that do not state a level.

Entry level

What the job is. You work under a senior technician or a licensed contractor. You carry tools, run line sets, help with installs, do filter changes and simple preventive maintenance, and learn the diagnostic process.

What employers ask for. Few postings say "entry level", so the bar is not always written down. The common baseline is EPA 608, basic OSHA safety, a driving licence and good customer service. Customer service appears in most technician postings. This is not a filler skill: you will explain problems and prices to homeowners and facility managers.

What to learn next. Electrical basics. Many postings ask for the ability to read electrical schematics.

Mid level

What changes. You run service calls alone. You diagnose faults, quote repairs and close the job with the customer.

What employers ask for. Preventive maintenance and reading electrical schematics and blueprints. Commercial employers often want experience with rooftop units, chillers or boilers.

What to learn next. Commercial and industrial equipment, building controls, and blueprint reading. Consider NATE certification. NATE describes itself as the largest nonprofit certification organisation for HVACR technicians in the US. It offers entry-level certificates and professional exams, and its certifications need recertification. NATE is voluntary. Few postings require it, so treat it as a way to stand out, not a gate.

Senior level

What changes. You take the hard calls, train juniors, and may lead a crew. Titles include "Master HVAC Technician" and "HVAC Team Lead". Many postings ask for senior or experienced technicians.

What to learn next. Licensing as a contractor, if your state has it. This lets you pull permits, supervise registered technicians, or start your own business. Some technicians move into warranty, controls, estimating or service management.

Country-specific rules: the US

Federal. EPA Section 608 is a federal requirement for refrigerant work. There is no single federal HVAC licence. Licensing is set by states and sometimes cities.

Texas as an example. Texas requires a licence from the Texas Department of Licensing and Regulation (TDLR) to install, repair or maintain air conditioning, refrigeration or heating systems (TDLR).

Texas credential	Requirements
Technician registration	$20 fee (checked October 2026), age 16 or older, valid 1 year, you work only under a licensed contractor
Contractor licence	48 months of air conditioning and refrigeration experience under a licensed contractor in the last 72 months, or 12 months as a certified technician plus 36 months in the last 48 months (a degree, diploma or certification in air conditioning and refrigeration can count toward an exception); an exam; $115 fee (checked October 2026); age 18 or older; liability insurance (Class A $300k/$600k, Class B $100k/$200k)

So in Texas the realistic path from first job to own contractor licence is at least four years. Other states have different rules, fees and exams. Check your own state board.

Foreign workers. A US licence or EPA certificate does not give you the right to work. You need US work authorisation first. Licensing boards may not accept experience from other countries. Check both before you move.

Common mistakes

• Taking open-book EPA Core and expecting Universal. An open-book Core result does not count toward Universal. Take the proctored Core if you want Universal.
• Treating OSHA 10 as a licence. It is a training card, not a certification or a licence to work.
• Skipping the state check. A course in one state may not meet the rules of the state you move to.
• Working without registration in a licensing state. In Texas, even a technician needs a registration and must work under a licensed contractor.
• Ignoring electrical skills. Many beginners focus on refrigerant work. Many technician postings ask for electrical schematics.
• Losing the driving licence. Most field technician postings mention one. A bad record can block you from most field jobs.
• Filtering only for "entry level". Few postings use that label. Read the requirements in unlabelled postings too.

FAQ

Do I need EPA 608 certification to work as an HVAC technician? Yes, if you service or dispose of equipment that can release refrigerants. The certificate does not expire (EPA).

Which EPA 608 type should I get? Type I covers small appliances, Type II high-pressure equipment and Type III low-pressure equipment. Universal covers all three. Universal does not limit you to one equipment type.

How long does it take to become an HVAC technician? Programs last about 6 months to 2 years, and apprenticeships last several years (BLS). In Texas, a contractor licence needs 48 months of supervised experience.

How much do HVAC technicians earn? The BLS median was $61,010 a year ($29.33 an hour) in May 2025 (checked October 2026). Pay in open postings on RoleFalcon is shown live on this page.

Do I need a driving licence? Usually yes. Most field technician postings mention one, and some ask for a clean driving record.

Is OSHA 10 a certification? No. It is voluntary training with a completion card (OSHA). Some employers, states or cities require it.
