Do I need a licensed HVAC contractor in Virginia?

Virginia requires HVAC contractors to hold the Class A/B/C Contractor License with HVA specialty (A: >$120K, B: $10K-$120K, C: <$10K) license from the Virginia Department of Professional and Occupational Regulation (DPOR). Verifying your contractor holds current credentials protects you on warranty claims, permits, and insurance coverage. Most licensing boards offer online license search tools to confirm active status before you hire.
