South Dakota to Connecticut: journeyman HVAC technician license reciprocity
South Dakota does not issue a statewide journeyman HVAC technician license, so there is nothing to transfer. Here is Connecticut's standard path for out-of-state applicants.
Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Journeyperson by equivalent out-of-state license (all states)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
An HVAC technician licensed in any other state applies under DCP's 'Heating Journeyperson - Equivalent Out of State License' path. DCP reviews one out-of-state license for equivalency: it must have required the same number of classroom hours (576 for the S-2), an equivalent classroom curriculum matching DCP's Exhibit A courses, and the same on-the-job training hours (8,000 for the S-2) as the Connecticut license applied for; the limited D-2 class needs 4,000 OJT and 432 classroom hours and the B-2 needs 2,000 and 288. The applicant submits a copy of the license, an official license verification, the laws and regulations that set the requirements met to obtain it, and the scope of work for that license; only one license will be reviewed and the $90 application fee is non-refundable. If the license is found equivalent, DCP approves the applicant to sit the S-2 exam with PSI ($59 per portion, eligibility valid one year), and the license is issued after passing on payment of the $120 initial license fee. The out-of-state license does not waive the Connecticut exam because Connecticut has no reciprocal agreements. If the license cannot be shown equivalent, the applicant must instead document 576 classroom hours and 8,000 OJT hours with transcripts and notarized employer letters under the equivalent experience and training path.
DCP's out-of-state license page does not itself restate that the exam is required; the exam requirement follows from the Heating, Cooling and Sheet Metal Work Licenses page (every individual applicant must take an exam), CGS 20-334a(a)(2) (competency shown by the state licensure examination) and the PSI bulletin (the State determines eligibility, then the candidate tests). CGS 20-333a permits licensure without examination only where the other state reciprocates for Connecticut licensees, and DCP states no such agreements exist. Many states issue a single HVAC or refrigeration license rather than a heating-piping-cooling license with a 576-hour curriculum, so an applicant may be found equivalent only to a limited class such as the D-2. Neither DCP page mentions EPA Section 608; it is a federal requirement that applies regardless. Typical processing time is not published.

How Connecticut licenses journeyman HVAC technicians
Connecticut journeyman HVAC technician · “S-2 Unlimited Heating, Piping and Cooling Journeyperson”
Statewide license
Connecticut licenses HVAC work statewide through the Department of Consumer Protection (DCP) as 'heating, piping and cooling' work; the journeyman-level credential is the S-2 Unlimited Heating, Piping and Cooling Journeyperson, which covers all heating, piping and cooling work defined in CGS 20-330 while employed by a licensed contractor. Narrower journeyperson classes exist for technicians whose experience is limited to part of the trade, chiefly the D-2 Limited Warm Air, Air Conditioning and Refrigeration Journeyperson (no oil burner servicing) and the B-2 Limited Gas and Oil Burner Journeyperson, plus D-4 cooling-only, G-2 gas piping and S-10 light heating-cooling classes. A new S-2 applicant qualifies through a Connecticut apprenticeship, through equivalent experience and training (8,000 on-the-job hours and 576 classroom hours), or by holding an equivalent out-of-state license, and in every path must pass the PSI-administered S-2 exam (70 questions, 3 hours, 70%, open book). DCP states that Connecticut does not have reciprocal agreements with any other jurisdiction, even though CGS 20-333a would allow the Commissioner to waive the exam for licensees of states that reciprocate. The application fee is $90, the exam is $59 per portion and the initial license fee is $120; licenses expire every August 31 and renew for $120. EPA Section 608 refrigerant certification is a separate federal requirement for anyone handling refrigerants.
Why South Dakota has nothing to transfer
South Dakota journeyman HVAC technician
Licensed by cities and counties
South Dakota has no statewide HVAC license at any level. The Department of Labor & Regulation's list of occupational licensing agencies includes Plumbing and Electrical Commissions but no mechanical, HVAC or refrigeration board, and the only state program touching heating equipment is the State Fire Marshal's boiler inspection program, which certifies boilers rather than the people who install them. Journeyman-level licensing exists only where a city ordinance creates it. Rapid City issues a Mechanical Installer (MI) license to individuals with four years of verifiable experience who pass the city exam and work under a licensed mechanical contractor; Sioux Falls issues no journeyman or technician license for mechanical work, so HVAC technicians there work as employees of a city-licensed Mechanical or Refrigeration Contractor without a personal license. Neither city publishes a reciprocity or endorsement path for out-of-state journeyman licenses: Sioux Falls states that it does not reciprocate any license, and Rapid City's code allows recognition of other agencies' licenses only for Class A and B general building contractors. An out-of-state HVAC journeyman therefore needs no state credential to work in South Dakota, must check each city where work will be done, and should expect to take Rapid City's installer exam if working there. EPA Section 608 certification remains a federal requirement for anyone handling refrigerants.
How local licensing works in South Dakota
How local licensing works. South Dakota has no state HVAC or mechanical licensing statute, so each city decides whether to license mechanical work under its building code ordinances. Outside the cities that do, no license is required beyond a building permit and federal EPA Section 608 certification for refrigerant work. Boilers are inspected and certificated by the State Fire Marshal's Office (Department of Public Safety), which does not license installers.
Sioux Falls. Chapter 150 of the city code licenses Mechanical Contractors, Refrigeration Contractors, Fireplace Contractors and Master Mechanics; there is no journeyman, installer or apprentice license for mechanical work (the city's journeyman and apprentice licenses are only for electrical and plumbing). Technicians work as employees of a licensed contractor whose master mechanic supervises the work. The city's FAQ states it does not reciprocate any licenses.
Rapid City. Chapter 15.26 of the municipal code creates the Mechanical Installer (MI) license for any person who installs, lays out, alters or repairs mechanical or HVAC systems, requiring four years of verifiable experience (an 18-24 month mechanical program counts as one year, a 9-12 month program as half a year) and approval by the Building Official; installers work under the direction of a licensed Mechanical Contractor, and Mechanical Apprentices (MA) work under the immediate supervision of an installer. Licenses are issued under chapter 15.04, which requires the city's examination, runs trade licenses for three years, and requires six hours of continuing education per license period for Mechanical Code licenses; exam and license fees are set by council resolution and are not published online. Nothing in the code recognizes an out-of-state installer or journeyman license.
Out-of-state holders. No South Dakota city page found publishes a reciprocity or endorsement path for an out-of-state HVAC journeyman license. In Sioux Falls there is nothing to transfer to; in Rapid City the installer applicant documents experience on the work record portion of the application and takes the city exam.
