Vienna HVAC licensure at a glance
21 current DPOR HVAC contractor licenses are registered in Vienna. The letters on Virginia licences are the state's project-size tiers - 15 Class A, 2 Class B and 4 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 Vienna license has been held 10 years, and 5 (23.8%) have been held 25 or more years. 2 Vienna licenses come from the state's legacy series, closed to new entrants in February 1992: membership alone proves licensure since before 1992, so those records rank at that bound - which can only understate their tenure - and never at a year the state did not publish. 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.
