About the AZ HVAC Exam
The Arizona HVAC contractor exam is the 80-question PSI R-39R/C-39 (CR-39) Air Conditioning and Refrigeration trade exam, taken alongside the AZ Statutes and Rules Training Course and Exam (SRE). It covers the residential R-39R, commercial C-39, and dual CR-39 classifications; the solar-inclusive R-39/C-79/CR-79 classifications add a separate 30-question solar exam. Four years of experience are required.

Frequently Asked Questions
What are the Arizona HVAC license classifications?
The Arizona ROC issues R-39R Air Conditioning and Refrigeration (residential), C-39 Air Conditioning and Refrigeration (commercial), and CR-39 (dual, combining C-39 and R-39R). Adding solar work requires R-39, C-79, or CR-79, which are the same classifications 'Including Solar.' All applicants pass the AZ Statutes and Rules Exam plus the PSI trade exam; the solar classifications add a separate 30-question solar exam.
How much experience do I need for an Arizona HVAC license?
A.R.S. 32-1122(B)(1) requires the qualifying party to have at least 4 years of practical or management trade experience in the classification applied for, at least 2 years of which must fall within the last 10 years. Technical training at an accredited college or university, or in a manufacturer's accredited training program, may substitute for no more than 2 of the 4 years.
What bond is required for Arizona HVAC contractors?
Residential specialty contractors (R-39R) post $4,250 for contemplated annual volume under $375,000 and $7,500 at $375,000 or more. Commercial specialty contractors (C-39) post $2,500 at $150,000 or less, rising through $7,000, $17,500, $25,000 and $37,500 to $50,000 for volume over $10 million. A dual CR-39 licensee combines the residential and commercial amounts.
How much does the Arizona HVAC contractor license cost?
The PSI trade exam is $66 (a solar exam adds $40, or $116 for two exams) and the AZ Statutes and Rules Training Course and Exam is $61 through GMetrix. A.R.S. 32-1126 caps the biennial application and license fee at $350 for a specialty residential license, $1,000 for specialty commercial, and $1,350 for specialty dual; residential and dual applicants also pay a Residential Contractors' Recovery Fund assessment capped at $600 per biennial period. Confirm current amounts on the ROC fee schedule.
Does Arizona require continuing education for HVAC contractors?
The Arizona ROC does not require continuing education to renew a contractor license. Licenses renew on a biennial cycle, and the renewal obligation is to keep the bond in force and pay the renewal fee and any recovery fund assessment. The Statutes and Rules Exam is a one-time requirement for new qualifying parties, not a recurring update.
