3. Complete the application. Enter the requested personal, apprenticeship, employment, experience, examination, and licensing information.
4. Gather supporting records. Documents may include apprenticeship credentials, a journeyperson certificate, employment verification, supervised experience records, and license verification from other jurisdictions.
5. Submit documents as instructed. Some materials may need to be completed or submitted by employers, supervisors, apprenticeship programs, schools, or licensing authorities.
6. Complete the applicable equivalency requirement. Applicants without a qualifying apprenticeship credential may need to complete the bypass examination section associated with the restricted specialty.
7. Receive Board approval to test. The Board reviews the application and supporting documentation before authorizing the master examination.
8. Register with the testing provider. Follow the scheduling instructions received after approval.
9. Take the examination. Follow the current rules for identification, approved references, calculators, appointment procedures, and testing conduct.
10. Complete the remaining license requirements. The Board reviews the official examination result and confirms that all requirements have been satisfied before issuing the professional license.
11. Establish the contracting business. Form the LLC or corporation, obtain the EIN, and complete the operational registrations associated with the new business.

Application Service is included with The 1 Package to help organize the Delaware licensing process. The service supports preparation of the application workflow and the information connected with the submission. Applicants remain responsible for providing accurate records and satisfying Delaware’s experience, examination, and professional requirements.

State Requirements

Delaware offers an unrestricted Master HVACR license and several Master HVACR Restricted specialties. Heating – Hydronic Systems and Gas Piping is one of the restricted classifications recognized by the state.

A restricted license authorizes services only within the specialty identified on the license. Professionals who intend to provide services across multiple restricted HVACR specialties must pursue the license classification appropriate for their complete scope of work.

One qualification pathway applies to applicants who received a journeyperson certificate after completing an HVACR or HVACR restricted apprenticeship program that meets the applicable standards. These applicants must document two years of post-apprenticeship HVACR or restricted HVACR experience under qualified supervision.

Applicants without the qualifying journeyperson certificate must document seven years of HVACR or HVACR restricted experience under the supervision of a properly licensed master professional. They must also complete the Board-approved apprenticeship equivalency requirements before receiving authorization for the master examination.

Experience records should demonstrate work relevant to hydronic heating systems and gas piping. Relevant work may include boilers, piping, pumps, valves, circulation systems, controls, fuel systems, maintenance, testing, inspection, and related HVACR services.

A Delaware professional license is separate from a Delaware business license. A contracting company may also need entity registration, tax accounts, insurance, permits, local approvals, and other operating credentials. The business formation, EIN filing, and contractor compliance guidance included in The 1 Package support this transition from licensed professional to organized business owner.
