Exam Details

The Delaware Master HVACR Restricted – Heating, Forced Air Systems, Ventilation, and Gas Piping examination evaluates the technical knowledge needed to work within this specialty. The examination covers forced-air heating systems, associated ductwork, mechanical equipment, gas piping, system sizing, installation, maintenance, and plan interpretation.

The published examination outline identifies 70 questions with a three-hour time allowance. The subject areas are divided as follows:

• General Knowledge: 15 questions
• Piping: 12 questions
• Systems and Sizing: 20 questions
• Equipment: 6 questions
• Maintenance: 12 questions

Candidates should practice reading the entire drawing before selecting an answer or beginning a calculation.

Open Book Test

The Delaware Master HVACR Restricted – Heating, Forced Air Systems, Ventilation, and Gas Piping examination is an open-book, timed test. Candidates may use authorized reference materials during the examination while following the testing provider’s current rules for approved books, tabs, highlighting, notes, inserts, calculators, and other materials.

An open-book format still requires focused preparation. Candidates must identify the subject of a question, decide which reference is most useful, locate the applicable information, and interpret it correctly. Searching unfamiliar books without a clear method can consume a significant portion of the testing period.

All books included in The 1 Package are highlighted and tabbed. The tabs help candidates move between important subjects, while highlighting draws attention to useful definitions, requirements, tables, diagrams, and technical explanations. These features are most effective when the books are used regularly throughout the course.

Develop a consistent search method during your preparation. Identify the key subject, select the most relevant book, use the index or table of contents, and read the complete section. Review nearby exceptions, notes, table headings, and conditions before choosing an answer.

The International Fuel Gas Code, 2018 supports study involving fuel gas piping, appliance connections, combustion air, venting, system installation, and related requirements. The International Mechanical Code, 2018 supports mechanical systems, ventilation, duct construction, equipment installation, exhaust, and related code topics. Modern Refrigeration and Air Conditioning, 22nd Edition provides broad technical coverage of HVACR principles, equipment, controls, service, airflow, heating, and system operation.

Candidates should review their current examination authorization and candidate instructions before test day to confirm which materials and book preparations are permitted at their specific appointment.

Licensing Steps

The Delaware Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners regulates Master HVACR and Master HVACR Restricted licenses. Applicants must complete the applicable licensing process and receive Board approval before sitting for the master examination.

1. Select the appropriate classification. Apply for the Delaware Master HVACR Restricted license and choose Heating – Forced Air Systems, Ventilation, and Gas Piping as the specialty.
2. Create or access a DELPROS account. Delaware professional licensing applications are submitted through the state’s online licensing system.
3. Complete the license application. Provide the requested personal, apprenticeship, employment, experience, examination, and licensing information.
4. Gather supporting documentation. Required records may include apprenticeship credentials, a journeyperson certificate, employment verification, supervised experience documentation, and license verifications.
5. Submit documents as directed. Some records may need to be completed or submitted by employers, supervisors, training programs, or other licensing authorities.
6. Complete any applicable equivalency requirement. Candidates without the qualifying apprenticeship credential may need to complete the relevant apprenticeship equivalency examination.
7. Receive Board approval to test. The Board reviews the application and determines whether the candidate meets the requirements to sit for the master examination.
8. Schedule and take the examination. Follow the registration instructions supplied after approval and comply with all current testing rules.
9. Complete remaining license requirements. The Board must receive the required examination result and supporting documentation before issuing the professional license.
10. Establish the contracting business. Form the selected business entity, obtain an EIN, complete applicable business registrations, and organize the company for professional operation.

The Application Service included with The 1 Package provides support with organizing and completing the professional license application. Final eligibility, authorization to test, examination results, and license issuance are controlled by the Delaware Board and the applicable testing provider.

State Requirements

Delaware recognizes an unrestricted Master HVACR license and multiple Master HVACR Restricted specialties. The Heating – Forced Air Systems, Ventilation, and Gas Piping classification limits the license holder to the services authorized within that specialty. Contractors who intend to offer services across multiple HVACR specialties may need to pursue the unrestricted Master HVACR classification.

Applicants with a qualifying journeyperson certificate earned after completing an accepted HVACR or restricted HVACR apprenticeship must document two years of post-apprenticeship HVACR experience under appropriate supervision. Experience earned before receipt of the journeyperson certificate does not count toward that two-year requirement.

Applicants who do not possess the qualifying journeyperson certificate must document seven years of HVACR or HVACR restricted experience under the direct supervision of a master HVACR licensee, master HVACR restricted licensee, or similarly licensed professional in another state. These applicants must also satisfy the applicable apprenticeship equivalency examination requirement.

Applicants must provide documentation that demonstrates experience relevant to the requested specialty. Records may need to be supplied by employers, supervisors, apprenticeship programs, schools, or licensing agencies. The Delaware Board determines whether the applicant’s training, experience, examination results, and other qualifications meet the state’s requirements.

A Delaware professional license is separate from a Delaware business license. Most contracting businesses need both professional authorization and proper business registration. Additional obligations may involve taxes, insurance, permits, employment accounts, local requirements, and recordkeeping.

The business formation and EIN services included in The 1 Package support the initial company setup. Contractor Compliance Guidance helps customers understand the operational steps that may follow formation. These services do not replace permits, insurance, local approvals, or other requirements that may apply to a particular business or project.

Test Information and Study Materials

Begin preparation by dividing the exam outline into manageable study areas. Create separate sessions for general knowledge, piping, systems and sizing, equipment, maintenance, and plan reading. Give additional time to systems and sizing because this category represents the largest portion of the published examination outline.

Use course lessons together with the included books. After reviewing a lesson, locate the related subject in the appropriate reference. This reinforces technical understanding while building the navigation skills needed during an open-book test.

Practice fuel gas sizing by identifying the correct table and confirming the system conditions before selecting a pipe size. Review developed length, connected demand, pressure, allowable pressure drop, and the notes that govern the table.

For mechanical-system questions, study duct construction, ventilation, exhaust, equipment installation, airflow, combustion air, and clearances. For maintenance questions, review system operation, troubleshooting sequences, component condition, controls, airflow restrictions, burner performance, and safe servicing procedures.

Plan-reading practice should include mechanical symbols, duct dimensions, equipment locations, piping routes, elevations, and system layouts. Read the complete plan before focusing on one measurement or component.

Complete timed practice sessions as the examination approaches. Answer familiar questions first, mark longer code searches or calculations, and return to them after completing the remaining items. Review incorrect answers and locate the supporting information in the books.
