Answer a few questions in 2 minutes. Free, no commitment.
Becoming an HVAC technician in Colorado does not require a state license, and that catches a lot of newcomers off guard. What you do need is training or an apprenticeship, a federal EPA Section 608 certification to handle refrigerants, and, in most cities, a local license tied to where you work. Colorado technicians earn a median of about $65,200 a year, roughly $4,000 above the national median, and most get there through a trade program of 12 to 18 months or an apprenticeship that runs a few years. The bigger question is usually not whether you can do the work, but which training path fits your budget and timeline.
HVAC Licensing in Colorado: Why It Depends on Your City
Because Colorado leaves HVAC licensing to local governments, the rules that matter are set by the city or county where you work. Two examples show how different they can be.
In Denver, higher-level work calls for local credentials like the Heating and Ventilating Journeyman or a Class A or B Supervisor certificate. Those require documented work experience, often two to eight years, plus a passing ICC exam. Those are credentials you grow into, though: you can start working at the entry level with your EPA Section 608 certification and earn them later as you log hours. In Colorado Springs and the Pikes Peak region, the city issues Mechanical Contractor licenses and Heating Mechanic IV credentials instead. Smaller towns may ask for little beyond your EPA certification.
The practical takeaway: decide where you want to work early, because that choice sets your licensing timeline more than anything else. A credential from one city does not automatically transfer to another, so confirm the local rules if you plan to move or work across city lines.
Frequently Asked Questions
Is 27 too late to start HVAC?
Not at all. HVAC is a common second career, and many people start training in their late 20s, 30s, or later. What matters is finishing your training and earning your EPA Section 608 certification, not your age. Employers hire on skills and reliability.
How long is HVAC school in Colorado?
A trade-school certificate usually takes 12 to 18 months, and an associate degree runs about two years. A full apprenticeship takes longer, commonly three to five years, though you are paid throughout. You can complete your EPA Section 608 certification during or right after your program.
Do you need a license to be an HVAC technician in Colorado?
There is no statewide HVAC license in Colorado. You do need a federal EPA Section 608 certification to handle refrigerants, and most cities require their own license for higher-level or contractor work. Check the rules for the city or county where you plan to work.
What qualifications do you need to become an HVAC technician in Colorado?
You need a high school diploma or GED, training through a trade program or apprenticeship, and a federal EPA Section 608 certification. Depending on your city, you may also need a local license. Optional credentials like NATE can raise your pay but are not required.
Choosing Your HVAC Path in Colorado
Becoming an HVAC technician in Colorado is one of the more accessible skilled trades to enter, and the path comes down to two decisions: how you train, a faster classroom program or a paid apprenticeship, and where you plan to work, since your city sets the licensing bar.
Once you know those two answers, finding the right program is the easy part. Line up your Colorado options and choose the one that matches your schedule and goals, then get started.
