How to Get an HVAC License in Colorado

Colorado has no statewide HVAC license. To get one, you apply through the city or county where the work happens, most often Denver's mechanical certificates and contractor license or the Pikes Peak Regional Building Department's (PPRBD) Heating Mechanic IV and mechanical contractor classes.

At a glance

• No state HVAC license: Colorado regulates HVAC work locally, not through a statewide board
• Colorado Springs repair route: PPRBD Heating Mechanic IV, $50 application, $10 annual license
• Denver company route: a supervisor certificate plus a separate $250 mechanical contractor license
• PPRBD company route: $50 application plus $100 per license class
• The offer: a flat $999 per state application if you want the paperwork handled for you

Every jurisdiction in Colorado sets its own HVAC licensing rules, so the first step is identifying where the work happens, not which statewide exam to take. This guide covers Denver and PPRBD, the two jurisdictions with the clearest published application paths, then walks through the company side: who qualifies the business once a crew is in place. For the state's broader licensing structure, see the Colorado contractor license guide; our contractor license overview explains how other states differ.

Who Needs an HVAC License in Colorado

Anyone installing, replacing, servicing or repairing heating, ventilating, air conditioning or related gas piping systems needs a credential from the local building department with jurisdiction over the job site. Neither Denver nor PPRBD builds a small-job dollar exemption into its mechanical rules the way some states do; the trigger is the type of work, not its price.

A technician doing repair and service work for an employer needs an individual credential, such as PPRBD's Heating Mechanic IV or a Denver journeyman certificate. A business that wants to contract for HVAC work, pull its own permits and hire crews needs a company license, which in turn requires a qualifying individual: a certificate holder in Denver, or a licensed examinee in a PPRBD company class. Covered refrigerant work also requires EPA Section 608 certification, a separate federal requirement layered on top of local licensing.

Outside Denver and PPRBD's jurisdictions, which the PPRBD jurisdiction page lists as unincorporated El Paso County, Colorado Springs, Fountain, Manitou Springs, Green Mountain Falls, Monument, Palmer Lake, Calhan and Woodland Park, contact the local building department directly. Boulder, Aurora and other Colorado cities run their own separate mechanical licensing programs not covered in this guide.

HVAC License Types in Colorado

Denver's mechanical certificates and company license

Denver distinguishes the individual's mechanical certificate from the company's contractor license, with separate experience tracks by trade.

Notes on the table:

• Denver requires notarized letters documenting the exact scope, dates and project addresses for every year claimed, completed within the last ten years.
• A supervisor certificate holder, either the applicant or a company employee, is required before the separate mechanical contractor license can be issued.
• Refrigeration Class B's residential scope is capped at systems of 5 tons or less.
• Gas service and steam/hot water routes exist too, with their own experience tables on Denver's mechanical certificates page.

PPRBD's company classes

PPRBD's mechanical contractor application separates company licenses by work scope rather than by years of experience.

Instead of a years-of-experience table, PPRBD requires three references, matching business and insurance names, a Certificate of Good Standing from the Colorado Secretary of State, and Workers' Compensation evidence or a documented exemption. The qualifying individual must actually supervise or manage the work; the application itself asks the applicant to confirm this in writing.

PPRBD's individual Heating Mechanic credentials

Heating Mechanic IV's gas scope is limited to leak repairs that do not alter or completely replace piping; installing or replacing gas piping falls under Heating Mechanic I or the company's own license instead. PPRBD's Heating Mechanic application does not set a fixed experience-year requirement for Heating Mechanic IV, only the scope and required instrument proficiency. PPRBD's mechanical contractor application states that an active Colorado journeyman plumbing license waives the exam for Heating Mechanic I.

The ICC Exams

Both jurisdictions test through Pearson VUE, but PPRBD's ICC testing page and its printed applications specify that only exams passed on or after January 1, 2016 are accepted, and no out-of-state exam results are accepted at all. That resolves what earlier PPRBD materials left ambiguous: there is one current cutoff date, published in the application itself, not several conflicting ones.

Neither department publishes or endorses a study guide. Candidates register and review the current exam content outline directly through Pearson VUE's ICC registration portal (pearsonvue.com/icc or 1-877-234-6082), which lists the reference codes each exam uses, such as the 2018 IMC and IFGC for PPRBD's master and Heating Mechanic exams.

How to Apply: Step by Step

1. Identify the jurisdiction. Confirm the job site falls inside Denver, PPRBD's territory, or another local department, and check that department's own rules.
2. Choose the credential or class. Match the planned work, residential or commercial, installation or repair only, to the specific certificate or company class.
3. Document experience and references. Gather Denver's notarized experience letters or PPRBD's three signed reference forms, covering the exact scope and dates claimed.
4. Register for and pass the exam. Schedule through Pearson VUE using the correct exam code for the receiving department; PPRBD will not accept an out-of-state result or an exam passed before January 1, 2016.
5. Assemble the company documents. For PPRBD, that means Good Standing, insurance, Workers' Compensation evidence and three references; for Denver, the certificate prerequisite plus the separate contractor license application.
6. Submit the complete application. PPRBD requires the full package at least three weeks before the Licensing Committee meeting it will be reviewed at; Denver reviews applications on its own schedule.
7. Obtain and track the license. PPRBD gives 60 days to claim an approved license before the file is voided; Denver gives 90 days after certificate approval to submit the official ICC passing letter.

Want the Application Done for You?

Tracking two different departments, two different reference and insurance packets, and a Pearson VUE exam registration is where most HVAC applications stall. The Licensing Company's License Application Processing prepares and submits the state contractor license application for you: an eligibility audit before anything is filed, a document checklist so you know exactly what to gather, every form prepared and reviewed line by line, submission the way the department requires, and the department's paperwork questions answered and resubmitted until it decides.

It is a flat $999 per state application, paid up front. State fees, exam fees, background checks and fingerprinting are paid to the state and to Pearson VUE, not to us. The service does not promise approval, does not promise a timeline, and does not take the exam for you. Call 615-219-2110 to talk through your Colorado application.

Colorado HVAC License Fees

Denver's fee schedule covers the company, supervisor and journeyman amounts above; current Pearson VUE exam prices are not published by either department, so none is stated here.

Bond and Insurance

Neither department's published mechanical application requires a surety bond. PPRBD requires liability insurance of $1,000,000 per occurrence and $2,000,000 general aggregate, with Workers' Compensation coverage or a documented state exemption, and Pikes Peak Regional Building Department listed as the certificate holder. Denver's general contractor insurance pages describe similar per-occurrence and aggregate limits, but a mechanical-specific figure was not published separately in the sources reviewed today; confirm current limits directly with Denver Contractor Licensing before applying.

How Long Does It Take

Denver's own mechanical certificates page states an application review time of approximately 14 to 20 business days, after which an approved certificate holder has 90 days to submit the official ICC passing letter and 90 days to pay the fee.

PPRBD runs on a monthly committee cycle: a complete application is due three weeks before the Licensing Committee meeting, supplemental documents are due ten calendar days before that meeting, and the Board of Review meets the following week to approve, condition or deny the recommendation. Once approved, an applicant has 60 days to obtain the license before the file is voided and a new application is required.

Renewal and Continuing Education

Denver's company, supervisor and journeyman credentials all renew every three years; the city's sources reviewed today do not establish a continuing education hour requirement for these mechanical credentials, so none is stated here.

PPRBD company licenses renew annually in the license's anniversary month, and only the examinee can complete that renewal. A PPRBD license that expires for longer than six months is administratively revoked, which requires a new application back through the Licensing Committee and Board of Review. Heating Mechanic IV licenses run 12 months from issuance, expiring at the end of that month, and renewal requires proof of at least six hours of approved technical training.

Qualifying Your HVAC Company

A Colorado HVAC company needs a qualifying individual: in Denver, a supervisor certificate holder who is either an owner or a full time W-2 employee supervising the work; at PPRBD, a licensed examinee who actually supervises, manages or oversees the workmanship, not just a name on the application. Neither department treats the credential as a document that can sit unused in a file while someone else runs the jobs.

If your company does not yet have someone who can fill that role, a qualifying agent can hold it while your own team builds toward licensure. Owners can read how to hire a qualifying agent and what a qualifying agent is to understand the role: a qualifying agent qualifies the company as either an owner or a full time W-2 employee who supervises the work, not a silent reference.

EPA Certification and Work Across Jurisdictions

EPA Section 608 covers refrigerant handling separately from local contractor licensing. The EPA issues four certification types: Type I for small appliances, Type II for high and very high pressure equipment, Type III for low pressure appliances, and Universal for all equipment; Universal certification requires a proctored core exam rather than the open-book option available for the other types. Apprentices may work without certification only under close, continuous supervision by a certified technician, and Section 608 certification does not expire. Our EPA 608 versus HVAC license guide explains how that federal credential differs from a local contracting license.

Denver does not reciprocate contractor licenses or certificates from other counties or states, and PPRBD does not reciprocate other building departments' licenses either. A company expanding from Colorado Springs into Denver, or the reverse, needs a new application in the receiving jurisdiction, even with existing credentials elsewhere. Related work may also call for separate Colorado electrical licensing or Colorado plumbing licensing review, since a mechanical credential does not cover those trades.

Colorado HVAC License Questions

Does Colorado have a state HVAC license?

No. Several sites describe a statewide exam through the Colorado Department of Regulatory Agencies, but DORA licenses only electricians and plumbers in Colorado. HVAC and mechanical work is licensed locally, by the city or county where the job site sits.

What is a Mech IV license in Colorado Springs?

Heating Mechanic IV is PPRBD's individual repair and service credential, held under an appropriate mechanical contractor's employment and direction. It covers HVAC repair and service plus limited gas leak repair, and requires combustible gas and carbon monoxide instrument proficiency.

What's the difference between Heating Mechanic I and Heating Mechanic IV?

Heating Mechanic I (Fitter) covers gas piping installation and repair and requires one year of experience. Heating Mechanic IV covers HVAC repair and service, with gas work limited to leak repairs that do not alter or replace piping. Both work under a licensed mechanical contractor's direction.

What does Denver require for a mechanical supervisor certificate?

Denver requires experience and an ICC exam matched to the specific certificate, with notarized supporting evidence, plus an official ICC passing letter submitted within 90 days of approval. Experience patterns differ by certificate, so use the row that matches the intended work.

Can a PPRBD license transfer to Denver?

No. Denver does not reciprocate contractor licenses or certificates from other counties or states, and PPRBD does not reciprocate other departments' licenses. Review the receiving department's own application requirements before assuming an existing credential is sufficient.

What does a Colorado HVAC license cost?

Denver charges $250 for a company mechanical license, $60 for a supervisor certificate and $40 for a journeyman certificate, each on a three year cycle. PPRBD charges a $50 application plus $100 per company license class, or a $50 application plus a $10 annual license for Heating Mechanic IV.

How long does it take to get an HVAC license in Colorado?

Denver's own page cites roughly 14 to 20 business days for application review, plus 90 days afterward to submit the ICC passing letter. PPRBD reviews applications on a monthly Licensing Committee cycle, with approval roughly four to five weeks after a complete submission, and 60 days to claim the license once approved.

Does EPA 608 let me contract for HVAC work?

No. EPA Section 608 is a federal technician certification for covered refrigerant work only. Local company licensing and a qualifying individual are still required to contract for the job.
