HVAC Exam Prep
Practice exam preparation for heating, ventilation, and air conditioning licensure and certification — state contractor programs and credential-specific programs — organized in one family hub.
PassProfessor HVAC Exam Prep covers the heating and air conditioning examinations in the expanding PassProfessor catalog. Each program is built to the licensing board’s published exam content and reference list for its state and credential, so candidates study the subject areas their exam actually covers.
HVAC licensure is granted by state licensing boards and agencies. Contractors are typically examined on the mechanical codes adopted by their jurisdiction — most often the International Mechanical Code and the International Fuel Gas Code — together with load calculation, duct design, refrigeration, electrical, and business and law material named on the board’s reference list; journeyman and technician credentials examine the trade skills at the working level. Some states license a single broad HVAC contractor credential, while others examine separate classes and specialties.
PassProfessor is exam preparation only. We are not affiliated with any state licensing board or code body, and our practice exams do not grant a license or credential. They exist to help you walk into exam day prepared and confident, ready to show what you know.
