Open Book Test

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

An open-book format does not eliminate the need for focused preparation. The listed books contain extensive technical information, and candidates cannot depend on researching every question from the beginning. Strong performance requires HVACR knowledge, calculation ability, and efficient reference navigation.

The highlighted and tabbed rental books in this Ultimate package are prepared to support that process. Tabs provide recognizable locations for major chapters, code sections, equipment topics, formulas, and calculation procedures. Highlighting helps selected information stand out during repeated review.

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 fuel-gas piping materials, sizing, appliance connections, regulators, shutoff valves, combustion air, venting, pressure testing, and installation safety.

Modern Refrigeration and Air Conditioning supports technical preparation involving refrigeration cycles, refrigerants, compressors, condensers, evaporators, metering devices, heat pumps, air-conditioning equipment, heating systems, 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. Preparation should include building construction, insulation, windows, doors, orientation, infiltration, climate, occupancy, and internal heat gains.

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

Candidates should complete timed exercises with all five references. Select a subject, identify the most appropriate book, locate the relevant section or table, and read enough surrounding material 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 identified 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 records are submitted through the state’s online licensing system.

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

Applicants for the restricted air-conditioning classification must provide the required CFC Certification documentation and qualifying education, apprenticeship, and work-experience records for the selected pathway.

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

An applicant without an acceptable journeyman certificate must document the required period of qualifying work experience under the supervision of a master licensee. The Board determines whether an Apprenticeship By-Pass Examination is also required.

Submit the completed application and all required attachments through DELPROS. The Board must review and approve the candidate before the official examination can be scheduled.

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

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

Complete the examination and earn the required passing score. Official results are reported through the testing and licensing process.

Finish any remaining licensing requirements after passing. Application Service is included to help organize licensing information and supporting documents, but final eligibility and license issuance remain under the authority of the Delaware Board.

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 provide services across multiple restricted specialties should pursue the unrestricted Master HVACR license.

The examination scope addresses air-conditioning and refrigeration systems, piping vessels, warm-air heating, boilers, ventilation systems, duct systems, insulation, and related components within complete systems.

Applicants must provide complete, accurate, and consistent documentation. Missing experience records, incomplete certification information, or conflicting application details may delay Board review and examination authorization.

Employment experience is generally verified by a supervisor. When standard verification cannot be obtained, alternative documentation may be submitted as allowed by the state licensing process. Acceptance 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.

The Delaware Board determines whether an applicant qualifies for examination and licensure. The testing provider administers the examination but does not decide whether an applicant satisfies Delaware’s professional licensing requirements.

After passing the examination, candidates must complete all remaining requirements before the license can be issued. Applicants should monitor DELPROS and their email for updates or requests for additional information.

Delaware HVACR licenses are subject to renewal, continuing education, and professional conduct requirements. A professional HVACR license is separate from any business registrations, insurance, tax accounts, or local approvals required to operate a company.
