How to Become an HVAC Technician in Colorado – HVAC Contractor License

Colorado is known for its beautiful landscapes and outdoor activities, but plenty of HVAC techs are needed to keep indoor spaces intact for residents. Heating, ventilation, and air conditioning (HVAC) positions are regulated independently by each city in CO. This means the steps to licensure are different depending on where you live in the state. 

To become an HVAC technician in Colorado, you’ll first need the right training through an apprenticeship or trade school program. After this, you’ll be able to pursue further certification or licensure to work as an HVAC tech in your city. 

We break it all down below, including the licensing procedures for the three most populated cities in the state: Denver, Colorado Springs, and Aurora.

Do You Need an HVAC License in Colorado?

As per national law, any HVAC tech working with refrigerants must get their EPA Technician Certification. 

Colorado, on the other hand, does not issue state-wide licensing for HVAC professionals. Instead, you must abide by the regulations of the city you’re working in. Some cities require you to take a test and be licensed by the city, while others will allow HVAC techs to work without a license so long as they’re employed by a licensed contractor.

This article will discuss HVAC training, as well as the HVAC licensing options in Denver, Colorado Springs, and Aurora as examples. 

HVAC Training in CO

Generally speaking, HVAC techs must be trained to work in the field. There are two main paths you can take. 

First, you could attend an HVAC trade school program. These are paid for out of pocket and focus on HVAC theory and classroom learning. Programs can range from six months long to two years. 

Second, you may want to become an HVAC apprentice. Apprenticeships combine classroom learning with extensive hands-on learning over four years. The work experience is usually paid. 

While some programs or apprenticeships may take on younger students, most require you to be 18+ with a high school degree or equivalent. 

EPA Certifications for HVAC Technicians

Any HVAC tech planning to work with refrigerants must have their EPA Technician Certification. This is a national requirement due to the Clean Air Act. Find an approved program to issue your certification exam before seeking employment to improve your job prospects in Colorado.

Denver issues four types of certificates for HVAC technicians in the city, as well as HVAC contractor licenses. 

  • Heating and Ventilating Journeyman Certificates are issued to HVAC techs who are employed by an HVAC contractor and have at least 4 years of experience (can be apprenticeship experience).

If you want to work in HVAC in Denver, you’ll first complete an apprenticeship or training program that has at least 7,000 hours of on-the-job training. This experience must be verified through notarized letters from your employers. 

If you meet these requirements, you should then take your HVAC journeyman exam. After passing this exam, you can apply for and receive your license. You can apply online, by mail, or in person.
