Exam Details

The Delaware Master HVACR 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 required test.

The examination evaluates knowledge connected with heating, air conditioning, refrigeration, ventilation, process cooling, process heating, gas piping, equipment installation, system sizing, testing, and inspection. Candidates should be prepared to apply technical concepts and locate information across multiple publications.

General HVACR knowledge may include heat transfer, pressure, temperature, humidity, airflow, refrigeration principles, combustion, electrical fundamentals, tools, safety practices, equipment operation, and trade terminology.

Piping subjects may include fuel-gas piping, refrigerant piping, approved materials, sizing procedures, supports, joining methods, valves, regulators, pressure considerations, testing, and protection from damage.

Equipment knowledge may involve furnaces, boilers, heat pumps, refrigeration systems, air-conditioning equipment, compressors, condensers, evaporators, metering devices, air handlers, burners, controls, and safety devices.

System-sizing and installation subjects may include heating and cooling load calculations, airflow requirements, equipment selection, duct sizing, installation clearances, distribution-system design, and proper placement of components.

Testing and inspection subjects may include pressure testing, leak testing, equipment startup, operational checks, performance verification, safety-control testing, inspection procedures, and evaluation of completed installations.

Candidates should divide their study time among code requirements, technical theory, equipment operation, calculations, and reference navigation. Studying only one publication may leave important exam subjects uncovered.

Open Book Test

The Delaware Master HVACR examination is an open-book test. Candidates may use authorized printed references under the current rules established by the examination provider.

An open-book examination still requires careful preparation. The books contain extensive technical information, and candidates may not have time to search every topic from the beginning. Efficient testing requires familiarity with the references and the ability to identify which publication addresses a particular subject.

The highlighted and tabbed references in this package are prepared to support that process. Tabs provide recognizable locations for major chapters, code sections, system topics, formulas, and calculation methods. Highlighting helps selected information stand out during study and timed practice.

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

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

Low Pressure Boilers supports review of boiler construction, burners, controls, fittings, safety valves, low-water protection, feedwater systems, combustion, water treatment, maintenance, and operating procedures.

Modern Refrigeration and Air Conditioning supports subjects involving refrigeration cycles, refrigerants, compressors, condensers, evaporators, metering devices, heat pumps, heating systems, electrical controls, troubleshooting, installation, and service practices.

Residential Load Calculation – Manual J supports residential heating and cooling load calculations. Candidates should understand how climate, insulation, windows, doors, orientation, infiltration, occupancy, and internal heat gains affect the final load.

The Ductulator supports duct-sizing calculations involving airflow, friction rate, velocity, round duct dimensions, and rectangular duct dimensions. Candidates should practice using it repeatedly before exam day so they can read and adjust the device efficiently.

Highlighted passages should always be reviewed in context. Definitions, exceptions, table notes, equipment conditions, and nearby provisions may affect the correct interpretation. Highlighting and tabs are navigation aids and do not replace reading the complete material.

Candidates should review the current testing rules before taking the examination. Requirements may address permanent tabs, highlighting, handwritten notes, inserts, loose paper, removable markers, photocopies, calculators, and other materials.

Licensing Steps

Begin by reviewing the Delaware Master HVACR license scope and confirming that the unrestricted license matches the services you intend to provide. Delaware also offers restricted HVACR licenses for specific specialties.

Create an account through Delaware Professional Regulation Online Services and begin the Master HVACR application in DELPROS. Delaware professional license applications are submitted through the online licensing system.

Gather the documentation required for the applicable licensing pathway. This may include license verifications, employment records, apprenticeship documentation, certification records, and other supporting information requested by the Board.

Applicants for an unrestricted Master HVACR license must submit the required certification and qualifying experience documentation. The exact application pathway depends on the applicant’s apprenticeship background, work history, and current licenses.

An applicant with an acceptable journeyman certificate must provide the apprenticeship program Certificate of Completion and the required qualifying experience obtained after receiving that certificate.

An applicant without an acceptable journeyman certificate must document the required years 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 reviews the application before authorizing the candidate to sit for the Master HVACR examination.

After receiving approval, follow the examination provider’s instructions to register and schedule the test. Review identification requirements, appointment procedures, calculator rules, permitted references, and book-preparation requirements before the examination date.

Prepare with the highlighted and tabbed books in this package. Review code subjects, refrigeration principles, heating equipment, boilers, gas piping, load calculations, duct sizing, testing, and inspection.

Complete the examination and earn the required passing score. After the Board receives the official result, complete any remaining licensing requirements shown in DELPROS.

Passing the examination is one part of the licensing process. Final eligibility and license issuance remain subject to the Board’s review of the complete application.

State Requirements

A Delaware Master HVACR license permits the license holder to design, install, construct, maintain, service, repair, alter, or modify products and equipment, including gas piping, used in heating, air conditioning, refrigeration, ventilation, process cooling, and process heating systems.

A Master HVACR Restricted license permits work only within the specialty listed on the license. Restricted specialties include forced-air heating, ventilation and gas piping; hydronic heating and gas piping; commercial hood systems; refrigeration; air conditioning; and gas piping.

Professionals who plan to offer services in more than one restricted specialty should pursue the unrestricted Master HVACR classification. Applicants should select the license type that matches their intended scope of work.

A Master Plumber license is also required when the work involves systems used to bring water into a building or remove liquid and water-carried waste. A Master HVACR license does not replace the plumbing authority required for that work.

Applicants must submit complete and accurate documentation. Missing employment verification, inconsistent experience records, incomplete certification information, or absent attachments may delay Board review.

The Delaware Board must approve examination candidates before they schedule the test. The testing provider administers the examination but does not determine whether an applicant qualifies for a professional license.

Applicants must satisfy the state’s passing-score requirement and complete all remaining licensing requirements before the professional license can be issued.

Delaware Plumbing and HVACR licenses expire on October 31 of even-numbered years. Licensees must complete the renewal process and meet the continuing education requirements that apply to their licensing period.

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