How to Get an HVAC License: Step-by-Step Guide
While the exact steps vary by state, here’s the basic progression you can expect in most places:
- Step 1: Start as an apprentice or helper, working under a licensed contractor.
- Step 2: Register as an apprentice if required in your state.
- Step 3: Gain hands-on experience through supervised work and/or formal training.
- Step 4: Complete any required classroom education (where applicable).
- Step 5: Pass the required exams (contractor, journeyman, or specialty license).
- Step 6: Apply for your state HVAC license and maintain it through renewals and continuing education.
It typically takes 2–5 years to meet the experience and education requirements for full licensure, depending on your state and the license type.
(If you were wondering how long it takes to get your HVAC license, that’s your ballpark answer, although exact timelines vary by jurisdiction.)
If your looking for an overview on how you get into HVAC, we’ve got a guide for that here.
A career that delivers real value
Below, you’ll find state-specific guides that show exactly how to get an HVAC license in your state. HVAC technicians are in demand across the country; whether it’s fixing aging equipment, installing the latest heat pumps, or keeping critical systems running. The work is steady, the pay is solid, and the long-term security is hard to beat.
The numbers back it up. The latest data from the U.S. Bureau of Labor Statistics shows that the median pay for HVAC technicians is $59,810 per year. Even better, the job market is expanding: HVAC employment is projected to grow 9% from 2023 to 2033, much faster than the national average for all occupations.
There’s plenty of opportunity, whether you want to work for a local contractor or build your own business.
Do you need a license to work in HVAC?
Most jurisdictions require an HVAC license to independently perform HVAC services. This is typically a license issued at the state level, but there are also a handful of states that leave the licensing up to local government.
When working under the employment and supervision of a licensed contractor or master HVAC technician, the answer depends on the State. Some states require a Journeyman License, and some pair the Journeyman license with a contractors license.
National HVAC Certifications
In addition to state licensing, anyone handling refrigerant must also earn an EPA 608 Certification. This is a federal requirement and applies nationwide.
National certifications also exist that, while not typically required for an HVAC license, can help set you apart and open up more job opportunities. Some examples of national HVAC certifications are:
