Dale City HVAC licensure at a glance
4 current DPOR HVAC contractor licenses are registered in Dale City. The letters on Virginia licences are the state's project-size tiers - 2 Class A, 1 Class B and 1 Class C here - shown as published and never ranked on: the dollar thresholds behind them are statute, not data in the extract, so we do not print them. Tenure is what these pages rank on, and Virginia's dates support it: the median Dale City license has been held 7 years, and 1 (25.0%) has been held 25 or more years. DPOR's extract carries no insurance, no bond and no phone for any licensee, so Virginia listings show none of the three - a gap in the state's file, not a finding about any contractor. DPOR cannot link straight to a record, so every listing above shows its number for you to paste into DPOR's license lookup. How we verify.
