Exam Details

The Delaware Master HVACR Restricted Forced Air Systems, Ventilation & Gas Piping examination evaluates the knowledge needed to perform work within this restricted HVACR specialty. Candidates should be prepared to address forced-air heating systems, ventilation, duct systems, fuel gas piping, equipment installation, system sizing, maintenance, troubleshooting, and mechanical plan interpretation.

The examination contains 70 questions and allows three hours for completion. The published examination outline divides the questions among the following subject areas:

• General Knowledge
• Piping
• Systems and Sizing
• Equipment
• Maintenance
• Plan Reading

Systems and sizing represent a major part of the examination. Candidates should be comfortable reviewing airflow, duct design, system capacity, equipment selection concepts, fuel gas demand, pipe sizing, ventilation requirements, combustion air, and installation conditions. Some questions may require using code tables or interpreting technical data.

General knowledge may include HVACR terminology, heating principles, heat transfer, combustion, airflow, tools, materials, controls, and accepted trade practices. Candidates may also encounter questions that require knowledge of how forced-air systems operate and how individual components work together.

Piping questions can involve fuel gas piping materials, joining methods, supports, protection, valves, regulators, appliance connections, testing, and sizing. A candidate may need to identify the correct code chapter, table, or installation requirement before selecting an answer.

Equipment questions may involve furnaces, burners, blowers, controls, safety devices, air-distribution components, and related mechanical equipment. Candidates should understand equipment operation as well as common installation and service considerations.

Maintenance questions may address inspection procedures, troubleshooting, cleaning, adjustment, system performance, airflow restrictions, burner operation, component condition, and safe servicing practices. Experienced technicians should still review terminology and procedures because exam questions may describe familiar field situations in a technical or code-based format.

Plan-reading questions may require candidates to interpret mechanical drawings, equipment locations, piping routes, duct layouts, symbols, dimensions, elevations, and system arrangements. Carefully review the entire drawing before focusing on one component or measurement.

Open Book Test

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

An open-book exam still requires detailed preparation. Candidates do not have unlimited time to search each reference from beginning to end. They must identify the topic, select the correct book, locate the applicable information, and determine how the requirement or technical principle applies to the question.

All rental books included in this package are highlighted and tabbed. The tabs help candidates move between frequently used subjects, while the highlighting emphasizes useful provisions, definitions, tables, diagrams, and technical explanations. These features are intended to support navigation, but they do not replace understanding the material.

The International Fuel Gas Code, 2018 supports questions involving fuel gas piping, system sizing, appliance connections, combustion air, venting, valves, regulators, testing, and installation requirements. The International Mechanical Code, 2018 supports ventilation, exhaust, duct systems, mechanical appliances, equipment installation, and related mechanical requirements.

Modern Refrigeration and Air Conditioning, 22nd Edition provides broader technical coverage of HVACR systems, forced-air heating, airflow, equipment, controls, service procedures, troubleshooting, and system operation. It may be especially useful for questions based on trade principles rather than a single code provision.

Practice identifying the likely reference before opening a book. Use the index, table of contents, chapter headings, tables, and cross-references. Once you locate a possible answer, read the surrounding material and check any applicable exceptions, notes, definitions, or table conditions.

Candidates should review the examination instructions issued for their appointment before test day. Only references and book preparations permitted under the current testing rules should be taken into the examination.

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 state application process and receive approval before taking the master examination.

1. Select the appropriate classification. Apply for the Delaware Master HVACR Restricted license and choose the forced-air heating systems, ventilation, and gas piping specialty.
2. Create or access a DELPROS account. Delaware professional license applications are submitted through the state’s online licensing system.
3. Complete the application. Provide the requested personal, apprenticeship, employment, experience, examination, and licensing information.
4. Collect supporting documentation. Required materials may include apprenticeship records, a journeyperson certificate, employment verification, supervised experience documentation, and license verifications.
5. Submit documents as instructed. Some records may be uploaded by the applicant, while others may need to be provided by an employer, supervisor, apprenticeship program, school, or licensing authority.
6. Complete any applicable equivalency requirement. Applicants without the qualifying apprenticeship credential may need to complete the apprenticeship bypass examination required for their licensing pathway.
7. Receive Board approval to test. The Delaware Board reviews the completed application and determines whether the candidate is eligible to take the master examination.
8. Register with the examination provider. Follow the scheduling instructions supplied after Board approval.
9. Take the examination. Bring only authorized materials and comply with all current identification, calculator, reference-book, and testing-center rules.
10. Complete remaining licensing requirements. The Board must receive the examination result and all required documentation before issuing the professional license.

Applicants should begin gathering documents early. Employment verification, apprenticeship records, and license verifications may require action by third parties. Incomplete applications may delay Board review and examination authorization.

This books and courses rental package does not include Application Service, government fees, examination registration, or licensing approval. Candidates remain responsible for completing the Delaware application and satisfying all applicable state requirements.

State Requirements

Delaware issues an unrestricted Master HVACR license and multiple Master HVACR Restricted licenses. A restricted license authorizes work only within the specialty identified on the license. The Forced Air Systems, Ventilation & Gas Piping classification does not automatically authorize every type of HVACR work covered by an unrestricted license.

The licensing pathway depends on the applicant’s apprenticeship background, journeyperson certificate, supervised experience, and other qualifications. Applicants with an acceptable journeyperson certificate issued after completion of a qualifying HVACR apprenticeship must provide proof of the apprenticeship and at least two years of applicable work experience under the supervision of a master licensee after receiving the certificate.

Applicants who do not have an acceptable journeyperson certificate must provide proof of at least seven years of work experience under the supervision of a master licensee. After the Board reviews and approves the experience, the applicant may also be required to pass the applicable apprenticeship bypass examination before receiving approval for the master exam.

Employment experience is generally documented through verification completed by the appropriate supervisor. Alternative records may be considered when a standard verification cannot be obtained, but acceptance of experience documentation remains subject to Board review.

The Delaware Board must approve applicants before they may sit for the master examination. Applications are submitted through DELPROS, and the Board reviews complete applications with the required supporting documentation.

A professional HVACR license is separate from a Delaware business license. A person who plans to operate a contracting company may also need business registration, tax accounts, insurance, permits, local approvals, and other credentials. This rental package supports examination preparation but does not include business formation or contractor compliance services.
