Highlighted passages should always be read in context. Definitions, exceptions, table notes, equipment conditions, and nearby provisions may affect the correct interpretation. Tabs and highlighting support navigation but do not replace understanding the complete material.

Candidates should review the current examination rules before test day. Requirements may regulate permanent tabs, highlighting, handwritten notes, inserts, loose paper, removable markers, photocopies, calculators, and other testing materials.

Licensing Steps

Begin by reviewing the Delaware Master HVACR license scope and confirming that the unrestricted license matches the services you plan to provide. Delaware also offers restricted HVACR licenses for specific specialties.

Create an account through Delaware Professional Regulation Online Services and begin the Master HVACR application in DELPROS. All applications are submitted through the state’s online licensing system.

Gather the documents required for the selected licensing pathway. These may include license verifications, employment records, apprenticeship documentation, certification records, and other supporting information requested by the Board.

Applicants for an unrestricted Master HVACR license must submit a copy of their CFC Certification card. Required periods of qualifying work experience must also be documented in the form accepted by the Board.

An applicant with an acceptable journeyman certificate must submit a copy of the apprenticeship program Certificate of Completion and proof of at least two years of work experience under the supervision of a master licensee after receiving the certificate.

An applicant without an acceptable journeyman certificate must submit proof of at least seven years of qualifying work experience under the supervision of a master licensee. The Board reviews the experience and determines whether an Apprenticeship By-Pass Examination is required.

Submit the completed application and all required attachments through DELPROS. The Board reviews the application before authorizing the candidate to sit for the Master HVACR examination.

After receiving approval, follow the examination provider’s registration and scheduling instructions. Review all appointment procedures, identification rules, approved references, calculator policies, and testing requirements.

Use the one-year online course and highlighted and tabbed rental references to prepare. Complete technical review, code-navigation exercises, load calculations, duct-sizing practice, equipment study, and timed exam activities.

Complete the examination and earn the required passing score. The official examination result must be received and accepted through the Delaware licensing process.

Complete any remaining application requirements after passing. Application Service is included to help organize the licensing information and supporting documentation, but final review and approval remain with the Delaware Board.

State Requirements

A Delaware Master HVACR license permits the license holder to design, install, construct, maintain, service, repair, alter, or modify products and equipment, including gas piping, used in heating, air conditioning, refrigeration, ventilation, process cooling, and process heating systems.

A Master HVACR Restricted license permits work only within the specialty shown on the license. Restricted areas include heating involving forced-air systems, ventilation and gas piping; hydronic heating and gas piping; commercial hood systems; refrigeration; air conditioning; and gas piping.

Professionals planning to provide services in more than one restricted specialty should pursue the unrestricted Master HVACR license. A current restricted license holder must complete the applicable process to upgrade to an unrestricted license.

A Master Plumber license is required in addition to HVACR authority when the work involves piping, fixtures, or apparatus used to bring water into a building or remove liquid and water-carried waste. The Master HVACR license does not replace plumbing authority for that work.

Applicants must provide state or jurisdiction license verification when required. Work-experience records must also be submitted for the periods applicable to the examination or reciprocity pathway.

Employment verification is generally completed by a supervisor. When a standard employment form cannot be obtained, other documentation may be submitted as allowed by the licensing process. Acceptance of experience documentation remains subject to Board review.

Candidates must receive Board authorization before scheduling the Master examination. The examination provider administers the test but does not determine whether an applicant satisfies Delaware’s licensing qualifications.

A minimum passing score of 70 percent is required. Applicants who do not pass after three attempts must reapply and obtain Board approval before testing again, subject to the applicable waiting period.

Delaware Plumbing and HVACR licenses expire on October 31 of even-numbered years. Licensees must complete the renewal process and satisfy the continuing education requirements that apply to their licensing period.

A Delaware professional HVACR license is separate from a business license. Individuals planning to operate an HVACR contracting company may also need a business entity, tax registrations, insurance, business licensing, and other operational approvals.
