Arizona to Iowa: master HVAC technician license reciprocity

No credit· Start overVerified September 15, 2026· 13 sources

Arizona does not issue a statewide master HVAC technician license, so there is nothing to transfer. Here is Iowa'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.

Out-of-state master or HVAC contractor (all states): direct admission to the Iowa master exam

Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.

Iowa has no master-level HVAC reciprocity with any state. An applicant who was previously licensed as a master in the applicable discipline in another state or local jurisdiction is admitted to the Iowa master HVAC/refrigeration exam without having to hold an Iowa journeyperson license first (Iowa Code 105.18(2)(c); 481 IAC 429.6(3)(i)); the applicant files the $35 exam approval application, pays Kirkwood's exam fee ($95 as listed on the master page), passes with 75%, and then files the post-examination licensure application with a prorated three-year fee ($240 for a full term). An applicant who has established Iowa residency may instead apply for licensure by verification under Iowa Code 272C.12 and 481 IAC 430.4, but the board still requires proof of passing the applicable Iowa licensing examination and can issue only a temporary license until then. To contract independently the master (or the firm employing the master) must also obtain the Contractor license and DIAL contractor registration ($250 plus $150 for a full term, 30% discount when bought with the master license in one transaction), with $500,000 liability insurance, a $5,000 surety bond, and for out-of-state contractors a $25,000 bond under chapter 91C; the board's reciprocity form states there is no reciprocity for contractor licenses.

Contractor license fees, insurance and bond are listed as optional requirements because they apply only to a master who contracts independently. The Kirkwood exam fee is quoted from DIAL's master page ($95); the journey page lists $99. Timeline reflects up to two weeks for exam approval plus up to six weeks for post-exam application review, excluding exam scheduling.

How Iowa licenses master HVAC technicians

Iowa master HVAC technician · “Master HVAC-Refrigeration”

Statewide license

Verified September 15, 2026· 7 sources

Issued by Iowa Plumbing and Mechanical Systems Board, Department of Inspections, Appeals, and Licensing (DIAL)

Iowa's highest person-held HVAC credential is the Master HVAC-Refrigeration license issued by the Plumbing and Mechanical Systems Board (DIAL); a Master Mechanical license, which adds sheet metal and hydronic work, is issued to anyone who passes both the master HVAC-refrigeration and master hydronic exams. A new master applicant must have previously been a licensed journeyperson in the discipline with at least two years of journey-level experience, or have been licensed as a master in the discipline in another state or local jurisdiction, and must pass the Iowa master exam (75%) through Kirkwood Community College. The separate Contractor license is a business credential: a sole proprietor or firm that contracts for HVAC work must hold or employ a master in each discipline, carry $500,000 liability insurance and a $5,000 surety bond (out-of-state contractors add a $25,000 chapter 91C bond), and register as a contractor with DIAL on the same application. Iowa has no HVAC reciprocity agreement with any state and states plainly that there is no reciprocity for contractor licenses. An out-of-state master may sit the Iowa master exam directly on the strength of the out-of-state license; Iowa residents may use licensure by verification but the board still requires the Iowa exam. Licenses run three years and require eight hours of continuing education per term.

Issued by Arizona Registrar of Contractors (contractor licensing only)

Arizona does not issue a master HVAC license. The state-level credential for heating, air conditioning and refrigeration work is a contractor license from the Arizona Registrar of Contractors (ROC) in the C-39 Air Conditioning and Refrigeration (commercial), R-39 Air Conditioning and Refrigeration, Including Solar (residential) or CR-39 (dual) classification; the license is issued to a sole proprietorship, partnership, LLC or corporation and qualified by a named qualifying party rather than to the technician personally, so this level is recorded as None. A master HVAC licensee arriving from another state who only wants to work for an employer needs no Arizona license (except a Phoenix journeyman card for permitted work there). To run an HVAC business the qualifying party must pass the open-book Arizona Statutes and Rules Exam (SRE, $61 through Gmetrix) and the classification trade exam ($66 through PSI), document four years of trade experience, complete a background check, register the entity if an LLC or corporation, post a license bond sized by classification and volume (residential specialty $4,250 to $7,500; commercial specialty from $2,500), and pay the application and license fees plus the residential recovery fund assessment ($580 for C-39, $720 for R-39, $850 for CR-39). Arizona has no direct reciprocity with any state, but the Registrar may waive the trade exam and experience documentation when the qualifying party held a comparable license in another state within the past five years that was obtained by trade examination (Out of State Waiver Request Form filed with the application); the SRE cannot be waived. EPA Section 608 certification applies to anyone handling refrigerants.
