Journeyperson by equivalent out-of-state license (all states)

The board reviews your out-of-state credentials case by case. Some exam is usually still required, often only a law or code exam.

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

Verified September 15, 2026· 6 sources

Issued by Connecticut Department of Consumer Protection, Occupational and Professional Licensing (Heating, Piping, Cooling and Sheet Metal Work Examining Board)

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.
