HVAC Contractor License in Colorado: Requirements, Qualifier, Bond and Exams

Locally, as far as our research goes: we did not confirm a statewide Colorado HVAC contractor license.

The state licensing pages our research read cover the plumbing and electrical trades, not HVAC, and the one HVAC issuer our research verified is a city: Denver.

Because no state source we read states that absence outright, treat it as unconfirmed rather than a guarantee, and ask the building department in every city and county where you will contract.

A federal rule follows the refrigerant work anywhere it happens: under 40 CFR 82.161, anyone who could reasonably be expected to violate the integrity of a refrigerant circuit while maintaining, servicing, repairing or disposing of appliances containing CFC/HCFC or non-exempt substitute refrigerants must pass an exam from an EPA-approved technician certification program.

No statewide HVAC agency appears in our research: the state licensing pages our research read cover the plumbing and electrical trades, not HVAC.

The issuing body our research verified is Denver's Community Planning and Development, Contractor Licensing.

The two Denver contractors our research names are the Heating and Ventilating Contractor Class A and the Heating Ventilating Air Conditioning Contractor — the two employers a Denver Heating and Ventilating Journeyman certificate holder may work for.

Contractor licensing in Denver is a two-step process, with the supervisor certificate (or a state electrical or plumbing license) clearing the way for the contractor license application.

Denver's contractor licensing is one general two-step: the contractor license applicant must hold a supervisor certificate or a state electrical or plumbing license, or employ someone who holds a supervisor certificate.

For heating and ventilating work, the commercial-and-residential supervisor certificate our research details is the Heating and Ventilating Class A Supervisor certificate: eight years of commercial heating and ventilating work, four as a journeyman mechanic and four as a designer, draftsman or supervisor, plus ICC exam F29 National Standard Master Mechanical.

The journeyman rung underneath takes four years — a minimum of 7,000 hours — of heating and ventilating field installation experience in an apprenticeship or on-the-job training, and ICC exam F31 National Standard Journeyman Mechanical.

A narrower residential route also exists: a Heating, Ventilating, A/C supervisor certificate covering air-conditioning refrigeration systems of 5 tons or less.

The exams our research verified are two ICC exams, and each attaches to an individual certificate rather than to the contractor license step: ICC exam F31 National Standard Journeyman Mechanical for the Heating and Ventilating Journeyman certificate, and ICC exam F29 National Standard Master Mechanical for the Heating and Ventilating Class A Supervisor certificate.

Our research names no business-and-law exam for Denver HVAC contractor licensing.

Ask the city's Contractor Licensing office whether any other exam applies before you file.

We could not verify a bond or insurance amount for Denver contractor licenses.

Bond and insurance rules for HVAC contracting are an open item here: ask the building or licensing department where you will work what it requires before you bid.

Denver's contractor license fees are not verified in our research, so we will not quote an application or renewal cost.

The verified clock belongs to the qualifier: Denver supervisor certificates must be renewed every three years, and the two-step requires your business's applicant to hold a supervisor certificate or a state electrical or plumbing license, or employ someone who does.

Confirm the fees and the contractor license's own renewal cycle with Denver Community Planning and Development when you apply.

Our research found no reciprocity agreement covering HVAC contracting in Colorado; with no statewide license confirmed, we found no state-to-state agreement to record either.

The substitution our research does show sits in Denver's general contractor-licensing rule, where the applicant may hold a state electrical or plumbing license in place of a supervisor certificate; how that substitution applies to an HVAC contractor application is not established in our research, so ask the city.

For an out-of-state contractor, the practical path is to start at the building department in the city where you will work and ask how your experience and credentials count toward its supervisor certificate and contractor license.

Denver's rule is written at the application gate — the applicant must hold a supervisor certificate or a state electrical or plumbing license, or employ someone who does, before applying — and our research does not say what the city requires after that.

Whether you must notify Community Planning and Development when your qualifier leaves, or name a replacement within a set time, is not established in our research.

Treat that as an open question rather than an all-clear: ask Denver before your qualifier gives notice, and line up the next qualifier's credential first.

Denver is the only Colorado city whose HVAC contracting rules our research verified.

Alongside the heating and ventilating certificates, its Contractor Licensing program issues Refrigeration Journeyman, Refrigeration Class A Supervisor, Refrigeration Class B Supervisor (residential, covering systems of 5 tons or less), Refrigeration Operator, and Gas Service Journeyman certificates — and the certificates are employment-tied: a Heating and Ventilating Journeyman certificate holder may perform that work only in the employ of a Heating and Ventilating Contractor Class A or an HVAC contractor.

Colorado Springs' Pikes Peak Regional Building Department was on our research list, but its HVAC licensing rules were not verified, and the state's other cities and counties were not researched.

The license question follows the job site, so ask the building department for every jurisdiction you bid.
