The full path into the trade: the steps, the career stages, every way in, what apprentices earn over time, and pay by state.
Five moves take you from no experience to a licensed hvac technician.
Math (especially algebra and geometry) and reading skills matter for trade exams and blueprint work.
Union apprenticeship, non-union shop, or trade school: each gets you there differently. See the full breakdown below.
Plan for about 3 to 5 years of paid, on-the-job training. Apprentices earn while they learn, and pay rises as hours are logged.
Most states require a state-licensed exam before you can work unsupervised as a hvac technician.
Stack credentials to raise your pay ceiling and move toward a master license. See which certifications matter.
HVAC has a clear, regulated path from helper to master. You start as an apprentice earning a wage while you learn, move up to a licensed journeyman running calls on your own, and can top out as a master who pulls permits and runs a business. Unlike some trades, you can be legally working and getting paid within months once you earn your EPA 608 certification, then build toward the higher licenses over the next several years.
Earning while learning
Entry into the trade, working under a licensed journeyman or master while you build field competency. You earn a wage the whole time and learn the foundations: the refrigeration cycle, basic electricity, airflow, and pipe work. Most programs run 2 to 4 years and combine on-the-job training with classroom instruction.
Day to day
Load the truck, run and strap ductwork, braze copper lines, mount air handlers, and handle basic maintenance like coil cleaning and filter changes under supervision
Key milestone
Earn your EPA Section 608 certification (required by federal law before you can handle refrigerant), then log your state's required on-the-job hours toward the journeyman exam
Licensed and working independently
The core working license. You run service calls and installs on your own out of your own van, troubleshoot system failures, and mentor the apprentices on your crew. This is where the path often forks toward residential service or commercial and industrial systems, and where pay jumps. Many technicians spend their whole career at this level and earn well.
Day to day
Diagnose failing systems with multimeters and gauges, recover and charge refrigerant to spec, read electrical schematics, and install split systems, heat pumps, and rooftop units without oversight
Key milestone
Accumulate 4,000 to 8,000 documented on-the-job hours, then pass your state or local journeyman mechanical licensing exam
Highest regulated license
The top license level. A master can pull permits, sign off on code compliance, supervise journeymen, and hold a contractor license to run an HVAC business. You handle the hardest service and install work and take responsibility for whether a job meets code. Requires additional years as a journeyman and a separate, more comprehensive state exam.
Day to day
Pull permits and own code compliance, supervise journeymen and apprentices, run quality control on installs, and optionally operate your own HVAC contracting business
Key milestone
Pass the Master Mechanical exam after accumulating your state's required journeyman hours, plus meet any insurance and bonding requirements if you pull permits independently
These are the three state-regulated license levels. Foreman and Senior are job titles assigned by employers, not regulated license tiers.
Regulated license levels vary by state. Some states have additional tiers or different naming conventions. Always verify current requirements with your state licensing board.

Hourly and annual figures are approximations based on typical union percentage ladders applied to the BLS national median. Actual pay varies by local union, employer, and region. Union locals in high-cost metros (New York, San Francisco, Chicago) typically pay 40 to 60% above these figures. Check your local UA wage schedule for exact rates.
Each path gets you there differently. Here's what each one costs, how long it takes, and who it's best for.
Union apprenticeship through the pipefitters or sheet metal workers. Earn a wage with full benefits from day one.
Merit-shop and single-employer apprenticeships with broad availability and a faster path onto job sites.
Classroom-first training that grounds you in fundamentals and helps you earn EPA 608 before you apply for an apprenticeship.
Entry pay varies by local union, employer, and region. Apprentice pay rises as you log hours, typically reaching journeyman scale by program completion.
