Exam Details

The Delaware Master HVACR Restricted Air Conditioning examination is part of the professional licensing process overseen by the Delaware Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners. Applicants pursuing licensure by examination must receive Board approval before scheduling the test through the approved testing provider.

The examination tests knowledge of the design, installation, maintenance, repair, fabrication, alteration, and extension of air-conditioning and refrigeration systems. The exam also addresses piping vessels, warm-air heating, boilers, ventilation systems, duct systems, insulation, and related components within complete systems.

The exam contains 95 questions, and candidates are allowed four hours to complete it. The timed format requires candidates to balance technical knowledge, calculations, plan interpretation, reference searches, and final review.

The examination outline includes General Knowledge, Plan Reading, Systems and Sizing, Piping, Equipment, and Maintenance. Each category requires candidates to connect practical HVACR experience with technical information and code requirements.

General Knowledge includes 22 questions. Candidates should review refrigeration principles, heat transfer, temperature, pressure, humidity, airflow, electrical fundamentals, combustion, safety practices, tools, insulation, system operation, and common HVACR terminology.

Plan Reading includes eight questions. Candidates may need to interpret mechanical symbols, equipment schedules, duct layouts, piping routes, system notes, dimensions, equipment locations, load information, and installation details.

Systems and Sizing includes 17 questions. Preparation should cover residential and commercial load calculations, equipment selection, system capacity, airflow, duct sizing, indoor and outdoor design conditions, building characteristics, ventilation loads, and equipment performance.

Piping includes 14 questions. Candidates should review refrigerant piping, fuel-gas piping, approved materials, joining procedures, supports, valves, regulators, sizing methods, pressure considerations, testing, and protection from damage.

Equipment includes 18 questions. Study should address compressors, condensers, evaporators, metering devices, air handlers, heat pumps, furnaces, refrigeration systems, motors, controls, safety devices, and related air-conditioning components.

Maintenance includes 16 questions. Candidates should understand system testing, troubleshooting, refrigerant-side evaluation, electrical checks, airflow measurements, leak detection, equipment cleaning, control verification, startup procedures, and preventive maintenance.

Open Book Test

The Delaware Master HVACR Restricted Air Conditioning examination is an open-book test. Candidates may use authorized printed reference materials under the testing provider’s current rules.

An open-book examination still requires careful preparation. The listed books contain extensive technical information, and candidates cannot depend on researching every question from the beginning. Strong preparation combines HVACR knowledge with efficient reference navigation.

The highlighted and tabbed rental books in this package are prepared to support that process. Tabs create recognizable locations for major chapters, code sections, load-calculation procedures, equipment topics, and technical subjects. Highlighting helps selected information stand out during study and timed practice.

The International Mechanical Code supports questions involving equipment installation, mechanical ventilation, exhaust systems, duct construction, refrigeration systems, warm-air heating, boilers, combustion air, chimneys, vents, clearances, supports, and mechanical-system requirements.

The International Fuel Gas Code supports questions involving gas-piping materials, pipe sizing, regulators, shutoff valves, appliance connections, combustion air, venting, pressure testing, and fuel-gas installation safety.

Modern Refrigeration and Air Conditioning supports technical preparation involving refrigeration cycles, refrigerants, compressors, condensers, evaporators, metering devices, heat pumps, air-conditioning systems, heating equipment, motors, electrical controls, troubleshooting, installation, and maintenance.

Manual N supports heating and cooling load calculations for small commercial buildings. Candidates should understand how occupancy, lighting, equipment, ventilation, construction, windows, orientation, infiltration, and design conditions affect calculated loads.

Manual J supports residential heating and cooling load calculations. Candidates should review how insulation, windows, doors, building orientation, infiltration, climate, occupancy, and internal heat gains influence equipment-sizing requirements.

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

Candidates should practice using all five books under timed conditions. Select a subject, identify the most appropriate reference, locate the relevant chapter or section, and read enough surrounding information to confirm the answer.

Current testing rules should be reviewed before exam day. Requirements may address permanent tabs, highlighting, handwritten notes, inserts, loose paper, removable markers, photocopies, calculators, and other test-day materials.

Licensing Steps

Begin by confirming that the Delaware Master HVACR Restricted Air Conditioning license matches the services you plan to provide. A restricted license permits work only within the specialty listed on the license.

Create an account through Delaware Professional Regulation Online Services and begin the applicable Master HVACR Restricted application in DELPROS. Applications and supporting documents are submitted through the state’s online licensing system.

Gather the records required for the licensing pathway. These may include current or previous license verification, apprenticeship records, employment documentation, certification records, and other supporting information requested by the Board.

Applicants for the restricted air-conditioning classification must provide a copy of their CFC Certification card. They must also document the qualifying education, apprenticeship, and work experience required for their application pathway.

An applicant with an acceptable journeyman certificate must submit the apprenticeship program Certificate of Completion and proof of at least two years of qualifying 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 must review and approve the candidate before the Master HVACR Restricted Air Conditioning examination can be scheduled.

After approval, follow the testing provider’s registration and scheduling instructions. Review identification requirements, appointment procedures, calculator rules, authorized references, and book-preparation policies.

Use the six-month online course and highlighted and tabbed rental books to prepare. Complete technical review, plan-reading exercises, load calculations, code-navigation practice, piping study, equipment review, and maintenance questions.

Complete the examination and earn a passing score of at least 70 percent. Official results are reported through the testing and licensing process.

Finish any remaining requirements shown in DELPROS after passing. Passing the examination does not automatically issue the license when documentation or other application requirements remain outstanding.

State Requirements

Delaware requires professionals providing regulated HVACR services to hold the appropriate state license unless a specific exemption applies. Holding a license in another jurisdiction does not automatically authorize HVACR work in Delaware.

A Master HVACR Restricted license permits services only in the specialty identified on the license. Delaware restricted specialties include forced-air heating, ventilation and gas piping; hydronic heating and gas piping; commercial hood systems; refrigeration; air conditioning; and gas piping.

The restricted air-conditioning classification applies to air-conditioning work within the state-defined specialty. Professionals planning to offer services across multiple restricted specialties should pursue the unrestricted Master HVACR license.

Applicants must provide license verification from each jurisdiction in which they currently hold or previously held a professional license when required by the licensing application.

Employment experience is generally verified by a supervisor. When standard supervisor verification cannot be obtained, alternative documentation may be submitted as permitted by the state. Acceptance of work-experience documentation remains subject to Board review.

A Master HVACR Restricted Air Conditioning license does not automatically provide authority for plumbing work involving systems used to bring water into a building or remove liquid and water-carried waste. Separate plumbing authority may be required for that work.

The Delaware Board determines whether an applicant qualifies for examination and licensure. The testing provider administers the exam but does not decide whether an applicant meets the state’s licensing qualifications.

Applicants who do not pass after three examination attempts must reapply and receive Board approval before testing again. The applicable waiting requirements must also be satisfied.

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 associated with their licensing period.

A professional HVACR license is separate from a business license. Individuals planning to operate an air-conditioning contracting company may also need a business entity, business registration, tax accounts, insurance, and local operational approvals.
