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, expansion, circulation, pressure, flow, system layouts, and the movement of hot water or steam through heating systems.

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

The controls category may include thermostats, aquastats, pressure controls, relays, operating limits, safety controls, valves, and equipment operating sequences. Candidates should understand how controls start, stop, regulate, and protect heating equipment.

Maintenance and testing questions may address equipment inspection, system startup, pressure testing, temperature measurements, preventive maintenance, troubleshooting, and the identification of unsafe or inefficient operating conditions.

General knowledge questions may involve accepted heating practices, system operation, equipment relationships, piping principles, and contractor-level trade understanding. Insulation questions may address heat loss, material application, system efficiency, and protection of piping or equipment.

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 book, locating the supporting information, and selecting an answer.

Connecticut contractor candidates may also need to complete the applicable Business and Law examination. That examination is separate from the S-5 trade test and uses its own approved reference, which is not included in this package.

Open Book Test

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

The International Mechanical Code, 2021 and Modern Refrigeration and Air Conditioning, 22nd Edition are the approved S-5 trade references included in this Ultimate package. Both rental books arrive highlighted and permanently tabbed.

Approved references may be highlighted, underlined, annotated, and indexed before the examination. Permanent tabs may be used to identify chapters, definitions, technical tables, equipment topics, piping subjects, controls, testing information, and other frequently reviewed material.

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.

The included highlighting and tabbing provide an organized navigation structure, but candidates should still review every marked section. A prepared reference is most useful when the candidate understands what each tab identifies and has practiced locating the supporting information before test day.

A practical open-book strategy begins with identifying the type of question. A code-based question involving boilers, mechanical equipment, piping, insulation, installation requirements, testing, or system safety may lead to the International Mechanical Code.

A technical question involving heating principles, equipment operation, system components, controls, maintenance, testing, or troubleshooting may be supported by Modern Refrigeration and Air Conditioning.

Candidates should use the permanent tabs together with the table of contents, index, chapter headings, diagrams, and technical tables. Not every possible question can be represented by a single tab, making familiarity with index terminology important.

Reading the complete supporting section is essential. Definitions, exceptions, notes, table headings, and surrounding paragraphs may affect the correct response. Candidates should avoid choosing an answer based only on an isolated highlighted phrase.

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, associated piping, controls, insulation, maintenance, testing, and system operation within the scope established by Connecticut.

The S-5 classification does not provide unlimited authority to perform every type of heating, cooling, refrigeration, fuel gas, oil burner, piping, or air-conditioning service. Contractors must remain within the authorized scope and obtain any additional Connecticut license required for work outside that scope.

Applicants must establish qualifying trade experience before becoming eligible for the contractor examination. Connecticut may review license history, supervised employment, apprenticeship completion, classroom instruction, and other supporting documentation.

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

Contractor candidates may need to complete both the S-5 trade examination and the applicable Business and Law examination. The business examination addresses responsibilities beyond technical heating work, including business organization, contracts, project administration, financial management, safety, and employment matters.

Holding the S-5 occupational license does not replace business registration, tax, insurance, permitting, or local requirements that may apply to a contracting company. License holders must continue to perform work within the limitations of the credential.

The included Application Service supports organization of the licensing submission, but candidates remain responsible for providing accurate information and satisfying all applicable state requirements.

Test Information and Study Materials

A productive S-5 study plan should begin with piping because it represents 17 of the 40 examination questions. Review piping materials, fittings, joining methods, supports, valves, insulation, expansion, circulation, flow, pressure, and system layouts.

Candidates should understand the differences between hot-water and steam systems. Study how heated water, steam, and condensate move through their respective systems, how circulation occurs, and how piping arrangements affect system performance.

Equipment accounts for eight questions. Review boilers, pumps, circulators, expansion tanks, air separators, heat exchangers, terminal units, control valves, and other components used in hot-water and steam heating systems.

Controls and maintenance each account for five questions. Candidates should understand thermostats, aquastats, pressure controls, relays, operating limits, safety devices, valves, equipment sequences, inspection procedures, testing, preventive maintenance, and troubleshooting.

Use the International Mechanical Code to review formal mechanical requirements. Pay close attention to definitions, tables, exceptions, equipment provisions, piping requirements, installation rules, and testing procedures.

Use Modern Refrigeration and Air Conditioning to reinforce heating principles, equipment functions, controls, operation, maintenance, and troubleshooting. Review diagrams, component relationships, and operating sequences rather than relying only on isolated terms.

The online course provides a structured way to review these subjects over one year. Candidates can study one category at a time, complete practice-oriented review, revisit weaker topics, and use the approved references to locate the supporting code or technical information.

During timed practice, identify the likely reference before opening a book. Use the permanent tabs to reach a major subject, then use the index, table of contents, chapter headings, and diagrams to locate the precise information.

Review missed questions carefully. Find the applicable code provision or technical explanation, determine why the original answer was incorrect, and study related concepts that may appear in a differently worded examination question.

How 1 Exam Prep Helps You Reach Your Goal
