South Dakota does not issue a statewide HVAC license. Sioux Falls does. The city requires a mechanical contractor license for HVAC work inside the city limits. Plumbing and electrical are separate licenses, and those start with a state license before the city exam. Look the mechanical contractor up with the city and ask who will pull the permit. This page shows which Sioux Falls HVAC companies AI assistants named most often across answers RecommendRadar ran and stored, how often each appeared, and the sources those answers cited.
