How South Dakota licenses HVAC work
There is no statewide HVAC contractor license that we could find; cities or counties license HVAC work.
Who licenses: Local governments
Local rules: The state Department of Labor and Regulation lists licensing boards only for electrical and plumbing (no HVAC or mechanical board), so HVAC is licensed locally; for example, Sioux Falls requires a Mechanical Contractor's License (with a Master Mechanic exam) for all HVAC work within city limits and a separate Refrigeration Contractor license, and we did not read the state statutes to confirm there is no other statewide rule.
Check your city or county building department's list of licensed contractors (Sioux Falls publishes one at https://www.siouxfalls.gov/business-permits/currently-licensed-contractors) and ask for the local license number.
Federal rule: in every state, technicians who handle refrigerant must hold EPA Section 608 certification, whatever the state or city requires.
We could not confirm every detail from South Dakota’s own sources, so treat this as a starting point and check with the agency.

Before you hire
Ask for the license number and check it on the official lookup where one exists. Ask for proof of insurance and a written, itemized estimate, and ask who pulls the permit if the job needs one – a new furnace, heat pump or air conditioner usually does.
