Requirements, license levels, and the issuing authority, sourced from Delaware's official board.
Delaware licenses at the master level and the board is the statewide licensing authority for HVACR work, so this is not a municipal state. The restricted master license is the practical route for a technician who works in one specialty only, for example refrigeration or air conditioning alone. Federal EPA Section 608 certification is separately required for refrigerant work, and Delaware reinforces it by requiring a CFC certification card with the application.
| Requirements | By examination: an applicant holding a journeyman certificate needs at least 2 years of experience under the supervision of a master after certification; an applicant without a journeyman certificate needs at least 7 years of work experience under the supervision of a master. The Master examination must be passed at a minimum score of 70 percent, and the applicant must hold a CFC certification card. License verification is required from every jurisdiction where the applicant is or has been licensed. No age, bond or insurance requirement is stated on the board's HVACR licensure page. |
| Reciprocity | The board states its terms directly. Applicants licensed in Connecticut or Maryland need not document experience. Applicants licensed in Alabama, Arkansas, the District of Columbia, Florida, Georgia, Michigan, New Hampshire, New Jersey, North Carolina, Ohio, Rhode Island, South Carolina, Virginia or West Virginia must demonstrate at least 7 years practicing as a Master in that jurisdiction. Applicants from other jurisdictions are evaluated by the board. |
| Renewal | Every 2 years; plumbing and HVACR licenses expire October 31 of even-numbered years. Continuing education is 5 hours per renewal for all renewals after the first; a first renewal requires 3, 0 or 5 hours depending on when in the cycle the license was issued. |
