Exam Details

The Connecticut Limited Heating, Hot Water and Steam Contractor (S-5) trade examination contains 40 questions. Candidates are allowed 1½ hours to complete the test, and a minimum score of 70 percent is required to pass.

The published S-5 examination content outline includes the following categories:

• Insulation: 1 question
• General Knowledge: 4 questions
• Controls: 5 questions
• Equipment: 8 questions
• Piping: 17 questions
• Maintenance and Testing: 5 questions

Piping is the largest examination category, accounting for 17 of the 40 questions. Candidates should devote substantial preparation time to piping materials, fittings, joining methods, valves, supports, insulation, circulation, expansion, system arrangements, flow, pressure, and the movement of hot water or steam through heating systems.

Equipment is the second-largest category. Preparation should include boilers, circulators, pumps, expansion tanks, air-control devices, heat exchangers, terminal units, valves, and other equipment used in hot-water and steam heating installations.

The controls section may include thermostats, aquastats, pressure controls, operating limits, relays, valves, safety devices, and equipment operating sequences. Candidates should understand how common control devices regulate system operation and protect heating equipment.

Maintenance and testing questions may involve inspection, system startup, pressure testing, temperature measurements, equipment checks, preventive maintenance, troubleshooting, and identifying unsafe or inefficient operating conditions.

With 90 minutes available for 40 questions, candidates have an average of approximately two minutes and fifteen seconds per question. This time includes reading the question, identifying the subject, choosing the appropriate reference, finding the supporting information, and selecting an answer.

The contractor licensing process may also require completion of the applicable Connecticut Business and Law examination. The included business book supports preparation for this separate examination.

Open Book Test

The Connecticut S-5 Limited Heating, Hot Water and Steam Contractor examination is an open-book test. Candidates may bring approved references into the examination center under the applicable testing rules.

The International Mechanical Code and Modern Refrigeration and Air Conditioning are included as the primary approved trade examination references. The other technical books in the package are supplemental study resources intended to strengthen the candidate’s understanding before the test.

Approved references may be highlighted, underlined, annotated, and indexed before the examination. Permanent tabs may be used to identify important chapters, tables, definitions, formulas, and technical subjects.

Temporary tabs, removable notes, loose papers, and inserted pages are not permitted. Candidates may not write in the books during the examination, and questions or answers may not be recorded inside the approved references.

Every book in this rental package arrives highlighted and tabbed. Candidates should review the marked sections, learn the tab system, and practice locating information throughout the course-access period. Prepared books are most useful when the candidate understands what each tab represents and has repeatedly used the references before test day.

A practical open-book strategy begins with identifying the type of question. Code-based questions involving boilers, equipment installation, piping, insulation, testing, or mechanical safety may lead to the International Mechanical Code. Technical questions involving equipment operation, controls, heating principles, maintenance, and troubleshooting may be supported by Modern Refrigeration and Air Conditioning.

Candidates should use tables of contents, indexes, permanent tabs, chapter headings, diagrams, and technical tables instead of searching page by page. Reading the complete section is important because definitions, exceptions, notes, and surrounding provisions may affect the correct answer.

State Requirements

The Connecticut S-5 credential is a limited contractor license for qualifying hot-water and steam heating work. The classification focuses on heating equipment, related piping, controls, insulation, maintenance, testing, and system operation within the scope established by Connecticut.

The S-5 classification is not an unlimited heating, cooling, fuel gas, oil burner, refrigeration, or air-conditioning license. Contractors must remain within the work authorized by the credential and obtain any additional Connecticut license required for services outside that scope.

Applicants must establish qualifying experience before receiving examination eligibility. Connecticut may review license history, supervised employment, apprenticeship completion, classroom education, and other supporting documentation.

Applicants using an equivalent experience or education pathway may need to provide detailed records showing the type and duration of training completed. The Connecticut Department of Consumer Protection determines whether the submitted qualifications satisfy the licensing requirements.

Contractor candidates should prepare for both the S-5 trade examination and the applicable Business and Law examination. The included Connecticut business reference supports review of business organization, contracts, project management, financial administration, employment responsibilities, safety, insurance, and contractor operations.

The included Application Service helps organize the licensing submission, but applicants remain responsible for providing complete and accurate information and satisfying all state requirements.
