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 examination, 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 significant preparation time to piping materials, fittings, joining methods, valves, supports, insulation, circulation, expansion, system layouts, flow, pressure, and the movement of hot water or steam through heating systems.

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

The controls category may involve thermostats, aquastats, pressure controls, relays, operating limits, safety controls, valves, and equipment sequences. Candidates should understand how common controls regulate system operation, protect equipment, and respond to changes in temperature or pressure.

Maintenance and testing questions may address system startup, inspection, 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, selecting the most appropriate reference, locating the supporting information, and choosing an answer.

Connecticut contractor candidates may also need to complete the applicable Business and Law examination. The included Connecticut contractor business book supports preparation for that separate test.

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 and Modern Refrigeration and Air Conditioning are included as the primary approved references for the S-5 trade examination. The other technical books in this package are supplemental study resources intended to strengthen the candidate’s understanding of hydronic heating, piping, system design, equipment operation, and practical trade calculations.

Approved exam-room references may be highlighted, underlined, annotated, and indexed before the examination. Permanent tabs may be used to mark important chapters, tables, formulas, definitions, 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 materials.

All rental books included in this package arrive highlighted and tabbed. Candidates should review the preparation system before exam day, understand what each tab identifies, and practice locating the marked material under timed conditions.

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

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

Licensing Steps

1. Review the S-5 classification. Confirm that the Limited Heating, Hot Water and Steam Contractor credential matches the work you intend to perform.
2. Meet the qualifying experience requirement. Establish the required properly licensed journeyperson experience or equivalent experience and training accepted by Connecticut.
3. Gather supporting documentation. Prepare license history, employment verification, apprenticeship records, classroom documents, and other qualification materials.
4. Complete the contractor application. Submit the applicable application and supporting information to the Connecticut Department of Consumer Protection.
5. Receive examination eligibility. The state reviews the submitted qualifications and determines whether the applicant may proceed to testing.
6. Prepare for the S-5 examination. Use the highlighted and tabbed books with the included online course to review piping, equipment, controls, insulation, maintenance, and testing.
7. Prepare for Business and Law. Study the included Connecticut contractor business book for the applicable Business and Law examination.
8. Schedule the examinations. Follow the testing provider’s registration instructions after eligibility is granted.
9. Complete the required examinations. Pass the applicable S-5 trade and contractor Business and Law examination portions.
10. Complete license issuance requirements. Submit remaining documentation, examination results, and licensing fees according to Connecticut’s instructions.
11. Return the rental books. Return all books within the rental period in similar condition to qualify for the refundable $500 deposit.

Passing the examinations does not automatically issue the contractor license. Applicants must complete Connecticut’s experience, application, examination, documentation, and license-issuance requirements.

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

Applicants relying on 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 applicable licensing requirements.

Contractor candidates should prepare for both the S-5 trade examination and the applicable Business and Law examination. The business examination addresses contractor responsibilities beyond technical trade work, including contracts, project management, business organization, financial administration, safety, employment matters, and risk management.

The S-5 contractor license and the contractor’s business entity serve different purposes. Forming a business does not replace the occupational license, and holding an occupational license does not remove the need to operate the business in compliance with applicable requirements.

These supplemental books can help strengthen understanding even though they are not listed as S-5 trade exam-room references.

For Business and Law preparation, review business organization, contracts, project management, accounting concepts, employment responsibilities, insurance, safety, and contractor administration. Practice locating information in the Connecticut contractor business book rather than relying only on memorization.

Timed practice should include identifying the likely reference before beginning a search. Use the permanent tabs, index, table of contents, and chapter headings to locate the supporting material, then review the complete section before selecting an answer.
