Exam Details

The Delaware Master HVACR Restricted Forced Air Systems, Ventilation & Gas Piping examination evaluates the knowledge required to provide services within this restricted HVACR specialty. The license applies to the specialty identified by Delaware as Heating – Forced Air Systems, Ventilation, and Gas Piping.

The published examination outline identifies 70 questions with a three-hour testing period. The subject areas include:

• General Knowledge: 15 questions
• Piping: 12 questions
• Systems and Sizing: 20 questions
• Equipment: 6 questions
• Maintenance: 12 questions
• Plan Reading: 5 questions

Systems and sizing represent the largest portion of the published outline. Candidates should prepare for questions involving airflow, duct systems, equipment capacity, heating loads, ventilation, combustion air, fuel gas demand, pipe sizing, system arrangements, and other design considerations. Some questions may require interpreting a table or technical diagram, while others may depend on practical HVACR knowledge.

General knowledge may include heat transfer, combustion, airflow, tools, materials, controls, equipment operation, terminology, and accepted trade practices. Candidates should understand how components work together within a forced-air heating and ventilation system rather than relying only on isolated definitions.

Piping questions may address fuel gas materials, joining methods, supports, protection, valves, regulators, appliance connections, pressure conditions, testing principles, and sizing. When using a code table, candidates must identify the correct system conditions before selecting a pipe size or capacity.

Equipment questions can involve furnaces, burners, blowers, controls, safety devices, air-distribution components, and related mechanical equipment. Maintenance questions may address inspection, cleaning, adjustments, airflow restrictions, component condition, troubleshooting sequences, combustion concerns, and safe service procedures.

Plan-reading questions may require candidates to interpret mechanical drawings, equipment locations, duct layouts, fuel gas piping routes, dimensions, elevations, symbols, and system arrangements. Careful review of the complete plan is important because the answer may depend on information shown in more than one part of the drawing.

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 references during the examination and must follow the current testing rules governing approved books, permanent tabs, highlighting, notes, inserts, calculators, electronic devices, and other materials.

An open-book format does not make the examination automatic or simple. Candidates have three hours to work through 70 questions. That requires technical understanding, time management, and an efficient method for locating information. Searching unfamiliar books page by page can use time that is needed for calculations and more difficult questions.

The included rental books are highlighted and tabbed to support preparation. Tabs provide convenient starting points for important subjects, while highlighting draws attention to useful definitions, requirements, tables, diagrams, and technical principles. Candidates should still read the complete surrounding section because exceptions, table notes, and related provisions may affect the correct answer.

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

Modern Refrigeration and Air Conditioning, 22nd Edition provides broad technical instruction covering heating principles, forced-air systems, airflow, controls, equipment operation, combustion, service procedures, maintenance, and troubleshooting. It can be used during preparation to strengthen the trade knowledge needed to understand and apply code requirements.

Before testing, candidates should review the current candidate bulletin and their examination authorization to confirm which books and editions are permitted in the exam room. Only references authorized under the current testing rules should be taken to the appointment.

Licensing Steps

The Delaware Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners regulates Master HVACR and Master HVACR Restricted licenses. Applicants pursuing the restricted Forced Air Systems, Ventilation & Gas Piping classification must complete the licensing process and receive Board approval before taking the master examination.

1. Select the correct license classification. Apply for a 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 Delaware Professional Regulation Online Services system.
3. Complete the online application. Provide the requested personal, employment, apprenticeship, experience, examination, and licensing information.
4. Gather supporting documentation. Required records may include a journeyman certificate, apprenticeship documentation, employment verification, supervised experience records, and verification of licenses held in other jurisdictions.
5. Submit documents as directed. Some materials may be uploaded by the applicant, while others may need to be completed or submitted by an employer, supervisor, apprenticeship program, school, or licensing agency.
6. Complete any applicable apprenticeship equivalency requirement. Candidates applying through the experience pathway without the qualifying apprenticeship credential may need to pass the applicable apprenticeship equivalency examination.
7. Receive Board approval to test. The Board reviews the application and supporting records before authorizing the candidate to sit for the master examination.
8. Register with the testing provider. After approval, follow the examination registration and scheduling instructions provided to you.
9. Take the examination. Follow all identification, reference-material, calculator, appointment, and testing-conduct requirements.
10. Complete the remaining licensing requirements. The Board reviews the official examination result and confirms that all licensing requirements have been satisfied before issuing a license.

Delaware requires a minimum score of 70 percent to pass the licensure examination. Applicants who do not pass after three attempts must apply again as a new applicant and obtain approval to retest. Delaware’s examination guidance states that a new application cannot be submitted until one year has passed from the date of the third unsuccessful examination attempt.

The Application Service included with this Ultimate package helps candidates organize the licensing application process and the information associated with their submission. It does not replace experience requirements, required examinations, government fees, or decisions made by the Board.

State Requirements

Delaware offers an unrestricted Master HVACR license and several Master HVACR Restricted specialties. The restricted Heating – Forced Air Systems, Ventilation, and Gas Piping license authorizes services within that specialty. A contractor who plans to provide services in more than one Delaware restricted HVACR specialty must pursue the appropriate unrestricted Master HVACR license.

Delaware law provides two primary qualification pathways. An applicant may qualify by holding a journeyman certificate issued after completing a qualifying HVACR or restricted HVACR apprenticeship program and then performing two years of applicable services under qualified supervision.

An applicant may also qualify by documenting seven years of HVACR or restricted HVACR services under the supervision of a properly licensed master professional and then successfully completing the apprenticeship equivalency examination approved by the Board. The Board determines whether submitted training and experience satisfy the requirements for the requested classification.

Applicants must achieve a passing score on the standardized examination designated for the Delaware license. Delaware law also includes professional conduct and fitness requirements. Additional certification requirements may apply to classifications involving the handling of regulated refrigerants.

HVACR or HVACR restricted services generally cannot be provided to the public in Delaware without the appropriate license unless a specific statutory exemption applies. Individuals working as apprentices, journeymen, mechanics, or other employees may perform services under the supervision required by Delaware law.

A Delaware professional license is separate from a Delaware business license. A person planning to operate an HVACR contracting company may also need business registration, tax accounts, insurance, permits, and local approvals. These business requirements are separate from the examination and professional license.

Test Information and Study Materials

Begin with a study schedule that divides the examination into general knowledge, piping, systems and sizing, equipment, maintenance, and plan reading. Give additional attention to systems and sizing because that category has the largest number of questions in the published examination outline.

Use the online course and rental books together. After completing a lesson, locate the related subject in the appropriate reference. This reinforces the technical material and develops the navigation skills needed for an open-book test.

For fuel gas sizing, confirm the pressure, demand, developed length, allowable pressure drop, and sizing method before choosing a table. Read the full table heading and notes. Selecting a value from the wrong table can produce an incorrect answer even when the arithmetic is accurate.

For mechanical systems, review ventilation, ducts, exhaust, combustion air, equipment installation, airflow, controls, and forced-air heating principles. For maintenance questions, study troubleshooting sequences, system inspection, component condition, burner operation, airflow restrictions, and safe servicing practices.

Use timed practice sessions as the examination approaches. Complete familiar questions first, mark questions requiring longer calculations or reference searches, and return to them later. Review missed questions by locating the supporting material and identifying why the correct answer applies.
