❄️ HVAC License Requirements by State
Pick a state to see exact experience, exam, fee, bond and insurance requirements.
HVAC (heating, ventilation and air-conditioning) licensing varies more than most trades: some states license it directly, others handle it locally or fold it into a mechanical contractor license. Separately, EPA Section 608 certification is required nationwide to handle refrigerants. Where a state license exists, expect experience requirements, a trade exam, a bond and insurance. Select a state below for the specifics.
