Best HVAC Schools in South Dakota (2026)

No, you do not need a state licence to work as an HVAC tech in South Dakota. The Department of Labor and Regulation lists the occupations it licenses, and while electrical and plumbing both appear, there is no HVAC or mechanical entry. The State Plumbing Commission's jurisdiction covers plumbing, sewer and water, appliance, on-site wastewater, manufactured home, underground irrigation and water conditioning work, and HVAC is not among them.

One adjacent credential is worth checking rather than dismissing. The Plumbing Commission does license appliance contractors and appliance installers, and it defines appliance installation to include making local connections to water and waste systems of miscellaneous and commercial equipment designed to use electricity or gas, along with maintaining and servicing that equipment. The core of that definition is water and waste connections rather than HVAC, but the gas element brushes against furnace and boiler work.

The rule text does not settle whether a particular gas-fired job falls inside it, so if your work involves servicing gas equipment in South Dakota it is worth asking the Commission directly rather than assuming either way. An appliance contractor needs a year of experience as an appliance installer, and an installer needs two years as an apprentice.

Sioux Falls requires a mechanical contractors licence of all contractors doing mechanical or HVAC work inside the city, and it offers no education substitution whatever. A master mechanic applicant shows four years of experience as a sheet metal mechanic, refrigeration technician, general manager, project manager or engineer in the employ of a licensed mechanical contractor, and must have spent at least 2,000 hours a year in that work.

Three licences issue from one application: mechanical contractor, refrigeration contractor and fireplace contractor. The fireplace tier needs no examination. The master mechanic exam runs four hours on the mechanical and fuel gas codes plus SMACNA standards and ACCA manuals; the refrigeration exam is two hours and open book. Exams are held on the second Wednesday of each month at a $75 fee, applications are due a week ahead, and the licence itself is $200 for a two-year cycle ending 31 December of odd years, with a $10,000 compliance bond.

One deadline catches people. You must submit the licence application within 90 days of passing the examination or you will be required to retest. The city also offers an inactive master mechanic licence that confers no right to work but keeps your standing current so you can reinstate without retesting, which exists precisely for that situation.

HVAC techs in South Dakota make a median of $61,390 a year, essentially level with the national median of $61,010. The Bureau of Labor Statistics counted 1,610 HVAC technician jobs in the state in its May 2025 wage survey, one of the smallest workforces in the country for the trade, concentrated in the two cities that do the licensing.

The bottom 10 percent earn $41,180 or less and the top 10 percent earn $86,940 or more, with the middle half between $49,930 and $74,120. For a rural state with no state licensing regime, that is a healthy distribution: the floor sits above the national floor and the middle holds up well, even though the ceiling falls short of the national 90th percentile of $95,210. These figures describe current pay rather than forecasting demand.
