State Requirements

Delaware offers an unrestricted Master HVACR license and several Master HVACR Restricted specialties. Refrigeration is one of the restricted classifications recognized by the state.

A Delaware Master HVACR Restricted – Refrigeration license authorizes the holder to provide services within the Refrigeration specialty. The restricted license does not provide the full scope of authority associated with an unrestricted Master HVACR license.

Professionals who plan to provide services across multiple restricted HVACR specialties must pursue the license classification appropriate for their complete scope of work. License holders are responsible for remaining within the authority granted by the state.

Applicants with a qualifying journeyperson certificate earned after completing an accepted HVACR or restricted HVACR apprenticeship must document two years of applicable post-apprenticeship experience under the direct supervision of a properly licensed master professional.

Applicants without the qualifying journeyperson certificate must document seven years of HVACR or restricted HVACR experience under the direct supervision of a Master HVACR licensee, Master HVACR Restricted licensee, or an individual holding a similar level of licensure in another jurisdiction.

Applicants using the experience pathway without a qualifying journeyperson certificate must also satisfy the applicable apprenticeship equivalency or bypass examination requirements before receiving approval for the master examination.

Experience records should demonstrate work relevant to refrigeration systems. Applicable experience may include equipment installation, refrigeration piping, commercial refrigeration, compressors, condensers, evaporators, controls, system maintenance, testing, troubleshooting, repair, and alteration.

Delaware applicants must also hold the appropriate certification for handling regulated refrigerants when required. The Delaware Board determines whether the applicant’s experience, training, examination results, certification, and supporting records satisfy the licensing requirements.

A Delaware professional license is separate from a Delaware business license. A contractor planning to operate a refrigeration business may also need entity registration, tax accounts, insurance, permits, local approvals, and other operating credentials.

Test Information and Study Materials

Begin preparation with a study schedule that divides general knowledge, piping, systems and sizing, maintenance, testing, and inspection into manageable sessions. Give additional time to general knowledge, piping, and systems and sizing because these areas represent most of the published examination outline.

Start with the basic refrigeration cycle. Review refrigerant condition and purpose as it moves through the compressor, condenser, metering device, and evaporator. Understand how pressure and temperature relationships make heat transfer possible.

Study major components individually and as parts of a complete system. Review compressors, condensers, evaporators, receivers, accumulators, expansion devices, solenoid valves, pressure controls, thermostats, motors, relays, and safety devices.

For piping preparation, review line purpose, sizing, supports, insulation, oil return, pressure conditions, valves, and common installation concerns. Learn how improper piping can contribute to poor system performance or equipment damage.

For mechanical-code questions, practice using the index and definitions. Locate provisions involving refrigeration systems, machinery rooms, ventilation, access, equipment installation, and protection. Read the complete section and review related exceptions or referenced provisions.

For maintenance and troubleshooting, connect operating symptoms with possible causes. Review pressure, temperature, airflow, refrigerant flow, electrical controls, dirty components, restrictions, improper charging, and mechanical failures. Evaluate the complete system rather than relying on one symptom.

Complete timed practice sessions as the examination approaches. Answer familiar questions first, mark longer reference searches or diagnostic problems, and return to them later. Review incorrect answers by locating the supporting information in the applicable reference.
