INTRODUCTION
This assessment consists of 100 original practice questions designed for the Indiana HVAC
Technician/Contractor Licensing Examination. The questions are based on publicly available examination
objectives, the International Mechanical Code (IMC), EPA Section 608 refrigerant handling requirements, and
Indiana regulatory standards . The assessment emphasizes foundational knowledge of HVAC systems, applied
troubleshooting skills, regulatory compliance, and critical decision-making in residential and commercial
scenarios . These are original practice questions and are not actual, leaked, recalled, secure, or live examination
questions.
,Question 1
What federal certification is required for technicians who handle regulated refrigerants in HVAC systems?
A. OSHA 30 Certification
B. EPA Section 608 Certification
C. NATE Master Technician Certification
D. ICC Mechanical Contractor License
🟢 Correct Answer: B. EPA Section 608 Certification
🔴 RATIONALE: EPA Section 608 Certification is federally required under the Clean Air Act for any technician
who handles regulated refrigerants, regardless of state licensing rules . OSHA 30 (A) is safety training, NATE (C)
is a voluntary industry certification, and ICC (D) is a code organization.
Question 2
Which of the following best describes the regulatory structure for HVAC contractor licensing in Indiana?
A. A single statewide HVAC contractor license issued by the state board
B. A federal-only licensing system with no local authority involvement
C. A fully unregulated system with no requirements for HVAC work
D. A decentralized system where licensing is primarily handled by local jurisdictions rather than a single
statewide HVAC contractor license
,🟢 Correct Answer: D. A decentralized system where licensing is primarily handled by local jurisdictions rather
than a single statewide HVAC contractor license
🔴 RATIONALE: Indiana does not issue a single statewide HVAC contractor license; instead, licensing authority is
largely delegated to local municipalities and counties, with additional federal requirements such as EPA
certification applying to refrigerant handling .
Question 3
What is the minimum passing score required on the Indiana HVAC contractor examination administered by PSI
Exams?
A. 65%
B. 70%
C. 75%
D. 80%
🟢 Correct Answer: B. 70%
🔴 RATIONALE: The Indiana HVAC Contractor License examination administered by PSI Exams requires a
passing score of 70% . Some local jurisdictions may have different passing requirements; for example, Evansville
requires 75% for certain license classifications .
, Question 4
What is the primary function of an HVAC system?
A. To generate electricity for building operations
B. To control indoor temperature, humidity, and air quality
C. To manufacture refrigerant for cooling processes
D. To produce oxygen for indoor environments
🟢 Correct Answer: B. To control indoor temperature, humidity, and air quality
🔴 RATIONALE: HVAC systems are designed to provide thermal comfort and maintain indoor air quality
through heating, ventilation, and cooling . They do not generate electricity (A), manufacture refrigerant (C), or
produce oxygen (D).
Question 5
What is the purpose of the compressor in a vapor-compression refrigeration cycle?
A. To absorb heat from indoor air
B. To release heat to the outdoor environment
C. To raise refrigerant pressure and temperature
D. To meter refrigerant flow into the evaporator
🟢 Correct Answer: C. To raise refrigerant pressure and temperature
