Glendale HVAC licensure at a glance
185 active ROC HVAC licenses are registered in Glendale. Every Arizona license carries a scope, and it is a legal boundary rather than a size tier: 157 of Glendale's licenses are dual scope (residential and commercial work) and 28 residential-only, while commercial-only licenses never appear on these pages at all - they do not permit residential work in Arizona. Tenure is what these pages rank on, and Arizona's issue dates are real and filled on every record: the median Glendale license has been held 6 years, the longest-standing since 1987, and 16 (8.6%) have been held 25 or more years. The posting list carries no insurance, no bond and no phone for any licensee - Arizona requires a license bond by statute but does not publish it, so we never show one, never claim one, and never rank on one. ROC's contractor search cannot link straight to a record, so every listing above shows its number for you to paste into ROC's contractor search. How we verify.
