How do you get an HVAC license in Colorado?
- Obtain EPA Section 608 certification, the one requirement that applies everywhere in Colorado regardless of city
- Start paid work with an HVAC company or formal apprenticeship, most jurisdictions want about 4 years of documented field experience
- Identify every jurisdiction you will work in and pull its specific mechanical license requirements, Denver, Pikes Peak (Colorado Springs), Aurora, and Larimer County all run separate systems
- Pass the local exam, in Denver, the ICC F32 National Standard Residential Mechanical exam through Pearson Vue ($115), and pay the local license fee
- If your work touches line-voltage wiring, add the Colorado state electrician license through DORA; gas piping may pull in the State Plumbing Board
What license tiers does Colorado offer?
The tiers are local, not state. Denver issues journeyman and supervisor mechanical certificates through Community Planning and Development. Pikes Peak Regional Building (Colorado Springs) runs Mechanic I through IV with escalating scope. Aurora, Boulder, Fort Collins, and Larimer County each maintain parallel systems. Layered over all of it: state electrical licensing through DORA for any line-voltage work.
What is the Colorado HVAC exam like?
Exams are set by each jurisdiction. Denver uses the ICC F32 National Standard Residential Mechanical exam through Pearson Vue at $115, plus Denver-specific code content for higher certificates. Other jurisdictions run their own ICC-based exams in the $75–$120 range. Expect altitude-corrected load calculation questions, the technical signature of Colorado licensing.
How much does an HVAC license cost in Colorado?
Costs depend entirely on where you work. Denver runs about $115 for the ICC exam plus roughly $60 for the license. Pikes Peak, Aurora, and Larimer County each charge separately, and insurance floors vary by jurisdiction, Pikes Peak demands the highest liability limits. Working the whole Front Range realistically means paying for two to four local licenses.
How long does it take to become an HVAC tech in Colorado?
The clock is the 4 years of practical experience, paid full-time work under a licensed contractor. Colorado has no statewide HVAC license, licensing lives at the city and county level, with Denver, Colorado Springs, Aurora, and most metro jurisdictions running their own mechanical licenses, typically after about four years of field experience.
Is HVAC a good career in Colorado?
Colorado average from state wage data (2025 estimate). National median from the U.S. Bureau of Labor Statistics (2023). Verify current figures with BLS.
What does it take to start your own HVAC business in Colorado?
Running an HVAC business in Colorado means clearing each city separately: local mechanical contractor license, local business license, liability insurance at that jurisdiction's floor ($300K–$1M depending on where), and Colorado workers comp from your first employee. No state bond exists, but several jurisdictions require their own. Map your service area first, the license stack follows the map.
What most guides get wrong about Colorado
Colorado's trap is jurisdiction-hopping: a Denver mechanical certificate means nothing in Colorado Springs, and each metro city licenses separately, a Front Range contractor may need three or four local licenses to cover their real service area. The second trap is altitude: at Denver's 5,280 feet, air density is about 82% of sea level, and standard sizing tables undersize systems by 15–25%, which is why local exams lean on altitude-corrected load calculations.
Colorado HVAC license: frequently asked questions
Do you need an HVAC license in Colorado?
There is no statewide HVAC license, but that does not mean unlicensed. Nearly every major city requires its own mechanical license: Denver issues certificates through Community Planning and Development, Colorado Springs runs Mechanic I–IV through Pikes Peak Regional Building, and Aurora, Boulder, and Larimer County have their own systems. Operating without the correct city license is illegal in every major Colorado market.
How do you get licensed in Denver specifically?
Denver requires about four years of HVAC field experience, passing the ICC F32 National Standard Residential Mechanical exam through Pearson Vue ($115 exam fee), and a license application with a roughly $60 fee through Community Planning and Development. Supervisor-level certificates require additional years.
Do Colorado HVAC techs need any state license at all?
Two scopes do cross into state licensing: electrical work, disconnects, control circuits, line-voltage thermostats, requires a Colorado electrician license through DORA regardless of your local mechanical credential, and gas piping can fall under the State Plumbing Board. Many working techs carry a local mechanical license plus a state electrical credential.
Is it worth getting licensed where Colorado does not require it?
Yes, beyond the cities that mandate it, a license means you can pull permits, bid your own jobs, and pass the credential checks homeowners and insurers increasingly run. EPA 608 remains federally mandatory for refrigerant work no matter what.
