Verified: 35 pages, between 2026-06-19 and 2026-10-01

There is no national hvac license. 35 states, 35 rulebooks — experience, exams, fees and the surety bond, compared side by side.

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.
