Arizona Residential HVAC Contractor License (CR-39)

ROC uses CR-39 Air Conditioning, Refrigeration and Heating as a dual classification, so the filing is broader than a simple residential HVAC registration. The issues that usually matter most are the dual-classification fee schedule, the bond amount that varies with annual volume, and the separate federal refrigerant credential that still sits alongside the ROC license.

What the CR-39 scope covers

ROC's classifications page says CR-39 carries the work allowed under the commercial and residential HVAC classifications. In practice, that means the licensee can install, alter, maintain, and repair air-conditioning, refrigeration, heating, and ventilation systems that fall inside those published scopes.

What ROC checks on the application

ROC's classification-requirements bulletin lists 4 years of experience for CR-39. Applicants also have to pass the SRE and the HVAC trade exam, submit background-check materials for everyone named on the filing, and provide a bond sized to the license's annual Arizona volume. ROC also expects current workers' compensation information or the correct exemption.

The current specialty-dual fee schedule totals $850, made up of a $100 application fee, a $380 license fee, and a $370 recovery-fund assessment.

Renewal and refrigerant reality

CR-39 renews every 2 years. ROC's current specialty-dual renewal schedule totals $650 for that cycle, and the renewal checklist adds a $50 late-renewal fee. The bond has to stay active at the right annual-volume amount, and workers' compensation information still has to be current when the license renews.

Separate from ROC, technicians handling refrigerant still need the federal EPA Section 608 credential. That rule matters for the work, but it is not part of the ROC license itself.

Why contractors still get exposed

ROC's public consumer guidance says a contractor license is required when the job needs a permit or when labor and materials exceed $1,000. Arizona treats contracting without the required ROC license as a Class 1 misdemeanor under A.R.S. § 32-1164. For HVAC businesses, the miss is often assuming the ROC license covers the entire compliance picture when refrigerant work brings a separate federal credential with it.
