Delaware to Idaho: master HVAC technician license reciprocity
Idaho has no reciprocity agreement with Delaware. A Delaware master HVAC technician applies by endorsement.

Universal licensure for out-of-state HVAC contractors (all states)
The board reviews your out-of-state credentials case by case. Some exam is usually still required, often only a law or code exam.
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 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. The board's published materials do not say whether any part of the exam is waived under 67-9409. The contractor application also requires an individual applicant to hold an active Idaho HVAC Journeyman license, or a business applicant to employ at least one, and the PSI contractor exam covers only the Contractor's Business and Law Reference Manual.

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). An individual applicant must already hold an active Idaho HVAC Journeyman license, or a business applying as an entity must employ at least one Idaho-licensed HVAC journeyman. 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.
