Colorado to Idaho: master HVAC technician license reciprocity
Colorado does not issue a statewide master HVAC technician license, so there is nothing to transfer. Here is Idaho's standard path for out-of-state applicants.
Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Universal licensure for out-of-state HVAC contractors (all states)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
With no reciprocity agreements, every out-of-state HVAC contractor or master is treated the same. Idaho Code 67-9409 obliges the HVAC board to license a person who holds a current, valid and unrestricted license in another state and demonstrates competency, on the standard application, fees and background checks, but lets the board require all or part of its examination; the board's rules require every contractor applicant to pass the board-designated exam and post a $2,000 bond, and DOPL publishes no HVAC-specific endorsement procedure. The realistic path is therefore the standard contractor application ($35), the PSI contractor exam ($75), the $2,000 compliance bond and the $225 license fee, with the out-of-state license and experience submitted as supporting evidence of competency.
Idaho's contractor exam covers business and law material (the DOPL Contractors' Business and Law Reference Manual is the allowed reference), so it is recorded as the trade exam rather than a separate law exam. Idaho Code 54-5013 sets a 24-month certificate term while DOPL's fee table shows a 3-year term for journeyman and contractor licenses; the fee table is the current practice. Whether the board waives any part of the exam under 67-9409 was not confirmed from an official page.

How Idaho licenses master HVAC technicians
Idaho master HVAC technician · “HVAC Contractor”
Statewide license
Idaho has no master HVAC title; its highest credential is the HVAC Contractor certificate of competency, which is issued as a card in the name of the individual who passes the board's contractor examination and is therefore mapped here to the master level (an HVAC business must hold or employ a certificate holder, and Specialty Contractor and Limited Heating Specialty Contractor certificates cover gas piping, hearth appliances and oil furnaces). The applicant pays a $35 application fee, passes the PSI-administered HVAC contractor exam ($75, using the DOPL Contractors' Business and Law Reference Manual as a reference), provides a $2,000 compliance bond, and pays the $225 license fee; the certificate renews for $150 every three years. Idaho's HVAC board states that it has no reciprocal licensing agreement. A contractor licensed in another state may apply under Idaho's universal licensure statute (Idaho Code 67-9409), which requires the board to license a person with a current, unrestricted out-of-state license who demonstrates competency, but allows it to require the Idaho exam; since DOPL publishes no separate procedure for HVAC, applicants should expect to take the contractor exam. EPA Section 608 certification is required nationwide to handle refrigerants.
Why Colorado has nothing to transfer
Colorado master HVAC technician
Licensed by cities and counties
Colorado issues no state master HVAC, mechanical or contractor license; the state licenses only electricians and plumbers, and mechanical licensing is left entirely to cities, counties and regional building departments. The master-level credential is therefore a local supervisor certificate or mechanical contractor license. Denver issues person-held Heating and Ventilating Class A and Class B and Refrigeration Class A and Class B supervisor certificates (6 to 8 years of experience plus the ICC F29 Master Mechanical or F32 Residential Mechanical exam, $60 for three years) and then licenses the mechanical contractor that employs the certificate holder ($250 for three years). The Pikes Peak Regional Building Department licenses Mechanical Contractors in classes H-A commercial, H-B residential and H-C specialty classes on the ICC W29 Master Mechanical, W32 Residential Mechanical or N33 Master Gas Pipe Fitter exams ($100 per license plus a $50 application fee). Neither jurisdiction recognizes out-of-state licenses: Denver does not reciprocate certificates from other counties or states and PPRBD accepts no out-of-state exams, so an arriving master HVAC contractor documents experience locally and passes the ICC exam required by each jurisdiction where they will pull permits.
How local licensing works in Colorado
How local licensing works. With no state mechanical license, each Colorado jurisdiction licenses mechanical contractors under its own code, nearly always on ICC National Standard exams (Pearson VUE, $100 each). PPRBD's notice says that 'often, contractors who work in several areas must pass an exam in each jurisdiction,' although many jurisdictions honor the same ICC certificate.
Denver. Licensing is a two-step process. First the individual obtains a supervisor certificate: Heating and Ventilating Class A (commercial and residential heating, ventilation and cooling up to 50 tons; 8 years of experience, 4 as a journeyman and 4 in design or supervision; ICC #F29 National Standard Master Mechanical), Heating and Ventilating Class B residential only (6 years; ICC #F32 National Standard Residential Mechanical), Heating, Ventilating, A/C residential only (6 years each in heating/ventilation and refrigeration; ICC #F32; refrigeration up to 5 tons), Refrigeration Class A (8 years; ICC #F29) or Refrigeration Class B residential only (6 years; ICC #F32). Experience is documented with notarized letters from employers or clients for projects completed within the last 10 years, and the ICC pass letter is due within 90 days of approval. Supervisor certificates cost $60 and renew every 3 years. Second, the business applies for a mechanical contractor license ($250, 3 years), which must be held by or employ a certificate holder. Denver 'does not accept or reciprocate contractor licenses and/or certificates from other counties or states.'
Colorado Springs and El Paso County (PPRBD). Mechanical Contractor licenses: H-A Mechanical Commercial (ICC W29 Master Mechanical), H-B Mechanical Residential (ICC W32 Residential Mechanical), H-C1 Gas Piping (ICC N33 Master Gas Pipe Fitter), H-C2 Commercial Refrigeration, H-C3 Residential Maintenance/Repair and H-C4 Residential Remodeling, each with a $100 license fee, plus a $50 application fee, references documenting relevant experience, a liability insurance certificate naming PPRBD (minimums in RBC201.7) and a name-based judicial record check; the Licensing Committee and Board of Review act on each application monthly. PPRBD accepts ICC National Standardized or ICC Colorado Standard exams passed on or after January 1, 2016 and 'no out-of-state exams will be accepted.'
Other jurisdictions. Only Denver and PPRBD were verified for this entry; other Colorado cities and counties license mechanical contractors under similar ICC-based ordinances and should be checked individually.
Out-of-state holders. No Colorado jurisdiction checked publishes reciprocity or endorsement for another state's master HVAC or mechanical contractor license. The practical route is to pass the ICC National Standard Master Mechanical (or Residential Mechanical) exam once and apply in each jurisdiction, each of which separately verifies experience.
