Who Needs a License in South Dakota?
There is no statewide HVAC contractor license in South Dakota. However, most HVAC installation, repair, and replacement work requires an Appliance Contractor or Appliance Installer license issued by the South Dakota Plumbing Commission, or appropriate city licensing.
Specifically, if you install, repair, or service heating, cooling, refrigeration, or mechanical appliance systems (including air conditioners, furnaces, and ventilation systems), you fall under Appliance Contractor/Installer requirements. In addition, many large cities like Sioux Falls or Rapid City mandate their own mechanical contractor licenses for HVAC work, so you must always check with both the state and local authorities before starting any project.
If you are working as an employee under a licensed contractor, you may not need a personal license, but the company or supervising contractor must be properly licensed. Conversely, if you operate independently as a contractor or sub, you absolutely must hold the correct state or municipal license for HVAC-related work.
HVAC License Types
South Dakota regulates HVAC and related trades through broader appliance and mechanical license classifications overseen by the Plumbing Commission. There is no state-level HVAC-specific license, but several Appliance and specialty contractor categories include HVAC tasks.
Appliance Contractor: Permits the contracting, installation, repair, and alteration of appliance-type mechanical systems. Examples include HVAC units, water heaters, and similar appliances. Requires one year of experience as an Appliance Installer.
Appliance Installer: Allows for the practical installation of appliances, including HVAC and refrigeration equipment, under the direction of a contractor. Requires two years of experience as an Appliance Apprentice.
Appliance Apprentice: Entry-level role working under supervision. Used for training those new to the trade. No prior experience required.
Other licensure categories: Specialized licenses exist for water conditioning, manufactured and mobile home installation, underground irrigation, plumbing, and sewer-water contracting. Some HVAC-related plumbing tasks, such as gas piping, could fall under a Plumbing Contractor/Plumber license and require further steps.
It's important to note that individual cities may have their own "Mechanical Contractor" or "Refrigeration Contractor" licensing requirements not covered by the state. Always confirm both state and local dues before starting HVAC work in South Dakota.
How to Get Licensed in South Dakota
To meet HVAC license requirements in South Dakota, you must follow a step-by-step state licensing process through the Plumbing Commission if performing work under Appliance Contractor or Installer categories.
Determine the correct classification for your work (Appliance Contractor, Installer, or Apprentice).
Document your experience: Contractors need one year as an Installer; Installers need two years as an Apprentice. Ensure you have accurate records and experience verification.
Obtain and complete the application: Access the correct form from the Commission’s Applications & Forms page. Specialty Contractor Application is used for appliance/mechanical; Plumbing Application for plumbing trades. (Specialty App PDF)
Gather documentation: Experience history, education if any, employment records, and if using reciprocity, proof of out-of-state licensing and continuing education.
Submit the application along with the correct processing fee by mail or fax to the address provided on the form. Application fees: $50 for Contractor/Installer; $20 for Apprentices (as of July 2, 2025, see official fee schedule).
Wait for the Commission’s review: Approval or deficiency notices are sent by email. Incomplete applications expire after 30 days.
Schedule your exam: Once approved, pay the $100 exam fee and schedule an exam session in Pierre, or at city dates when available. Temporary licenses are available ($50) if needed before the exam.
Sit for and pass the exam: Check the Commission website for study materials and dates.
Upon passing, pay your license fee: Appliance Contractor annual fee is $200. Commission then issues your license.
Renew annually and complete any required continuing education: Track your license status and renewal deadlines to avoid lapses or penalties.
City-Level Licensing Steps
If you work in Sioux Falls, Rapid City, or another city with its own licensing board, you must also complete the city’s mechanical/HVAC contractor licensing application. Each city has separate forms, local exam processes, and fees. Always contact the city Building Department or Licensing Board directly.
Application Requirements
Meeting HVAC license requirements in South Dakota means fulfilling several state application requirements. Each step involves gathering specific evidence and completing Commission-mandated forms.
Age and Experience
You must be at least 18 years old. To become an Appliance Contractor, provide proof of one year as an Appliance Installer. Applicants for Appliance Installer must show two years as an Apprentice. Experience is verified with employer documentation or apprenticeship logs. Unlike some trades, there is no published work-hour minimum for appliance categories, but plumbing applicants must show 1,900 hours per year; similar diligence is recommended for appliance trades.
Documentation and Forms
The Specialty Contractor Application and Plumbing License Application forms each require your basic details, work history, and signature. Submit the completed application by mail or fax. Applications expire if not completed within 30 days of receipt by the Commission.
If applying for reciprocity, you must furnish verification of your out-of-state license and evidence of at least four hours of recent continuing education. All application fees must be included by check or money order, or you may call in a credit card payment for the exam/license portion after application approval.
Bond and Insurance
South Dakota does not require a license bond or insurance at the state level for Appliance Contractor/Installer licensing. There are also no general minimum coverage requirements for this category. Individual cities, however, may require bonds or insurance for mechanical contractor work: always check city ordinances for additional local requirements.
Background and Federal/State Checks
The form includes questions about felony convictions and disciplinary actions on previous licenses. While the Commission does not list an explicit background check process for Appliance category applicants, all disclosure fields must be answered honestly; false statements may lead to denial or revocation.
Federal EPA Section 608 certification is required for any technician working on refrigerants (not a license, but a mandatory credential). If you handle refrigerants, maintain and be ready to show your EPA credentials for compliance purposes.
Exams
To fulfill HVAC license requirements in South Dakota as an Appliance Contractor or Installer, you must pass the relevant state exam. The exam is administered by the Plumbing Commission and is required before initial licensure.
Exam fees are $100 for Appliances Contractor and Installer categories (as of July 2, 2025, see ARSD 20:53 for fee confirmation). Exams are scheduled anytime by appointment in Pierre, with periodic sessions offered in Sioux Falls and Rapid City when at least 8–10 applicants have signed up. Upcoming city exam dates are posted on the Commission’s exams page. For 2026, Sioux Falls is scheduled for July 10 and Rapid City for July 24.
The Commission does not publicly release the state exam’s content breakdown, question count, or passing score. You must contact the Commission for study resources and details. In contrast, some city-level exams (such as Sioux Falls' Mechanical Contractor exams) are open-book, multiple-choice, and time-limited, but these are separate from state exams.
After submitting your application and being approved, pay the exam fee and arrange your session. Temporary licenses are available if you need to work before an exam slot opens (fee: $50). After passing the exam, pay your licensing fee and the Commission will issue your credential.
Fees
All major fees relating to HVAC license requirements in South Dakota are specified in Administrative Rule ARSD 20:53, effective July 2, 2025. Always verify amounts before submitting any payment on the Commission licensing page.
Appliance Contractor Application: $50 (as of July 2, 2025, see fee schedule).
Appliance Installer Application: $50 (as of July 2, 2025, see fee schedule link above).
Apprentice Application: $20 first year ($30 year 2, $40 year 3, $50 year 4+).
Exam or Re-exam: $100 (Contractor/Installer) as above.
Annual License/Renewal: $200 (Appliance Contractor), $105 (Installer), fee varies for others.
Temporary License: $50.
Duplicate/Replacement License: $10.
License Verification Request: $20.
Note: The state does not require or charge for a surety bond or insurance minimum for Appliance Contractor/Installer licensing. City-level fees and requirements may differ; check with your local department if applying in Sioux Falls, Rapid City, or other municipalities.
Renewal and Continuing Education
To continue meeting HVAC license requirements in South Dakota, all Appliance Contractor and other Commission-issued licenses must be renewed by December 31 annually. Renewal paperwork is distributed every April for the upcoming cycle, and forms are posted on the applications page of the Commission’s website.
Annual Renewal Process
Renew by mailing the renewal form with the appropriate fee to the Commission before the December 31 deadline. If the license lapses, you must submit a reinstatement request and pay a reinstatement fee (amount not specified, check directly with the Commission). If you perform work for more than 60 days with an expired license, you risk disciplinary action under state rule ARSD 20:53.
Continuing Education
Continuing education is required each year for plumbing-level license holders (contractor, restricted contractor, plumber, restricted plumber, and third-year apprentice). Appliance Contractor and Installer categories are not currently required by the Commission to complete CE, but you must confirm at each renewal. The minimum for plumbing is four hours, with at least two hours covering code topics. Proof is required before your license can be renewed.
If audit or renewal checks reveal a deficiency, your license will not be reissued until you complete all outstanding CE hours. Providers and instructions are available from the Commission’s Continuing Education page.
Reciprocity
South Dakota allows some out-of-state license holders to obtain a state Appliance Contractor, Installer, or plumbing license by reciprocity. To qualify, you must submit proof of equivalent out-of-state licensure, evidence of at least four hours of recent continuing education, and satisfy the exam requirements by taking the South Dakota Commission exam. All reciprocity applicants use the standard Plumbing License Application, checking the box for "License by reciprocity" and attaching all corroborating documentation.
The Commission reviews all reciprocity documentation directly. Licensing staff will notify you if your experience and qualifications meet the state’s equivalency standard or if you must provide additional details. After approval, pay the relevant exam and licensing fees as required for new applicants. Reciprocity does not guarantee a waiver of the state exam, as you must still pass the South Dakota exam to obtain a state license under current Commission rules.
