Kentucky HVAC Exam Prep: 1,450 Practice Questions for the Master HVAC Contractor Exam
PassProfessor’s Kentucky HVAC Exam Prep is built for candidates for Kentucky’s Master HVAC Contractor license, issued by the Department of Housing, Buildings and Construction, Division of HVAC. The bank holds 1,450 original practice questions: a 1,250-question HVAC core covering the trade itself, plus 200 Kentucky questions on Kentucky law, business and law, and trade application.
Every question is an original item written for this program, and every question comes with an explanation for every answer: why the keyed answer is right and why each other option is wrong, grounded in the cited code, standard, manual, or rule.
The exam, in facts
- Kentucky licenses HVAC through the Department of Housing, Buildings and Construction (Division of HVAC) under KRS 198B.650-.689 – there is no HVAC board. The ladder runs Master HVAC Contractor (license), Journeyman HVAC Mechanic (license), and Apprentice (a certificate issued by registration).
- The examinations are the Department’s own in-person exams – no testing company administers them. Both the Master and Journeyman exams are open book, and the passing standard set by rule (815 KAR 8:010) is at least 70%.
- The Master exam’s reference list is exactly two books: NFPA 54, the National Fuel Gas Code, 2009 edition, and the International Mechanical Code, 2015 edition. The Journeyman list differs – NFPA 54 (2009) with the International Residential Code 2015 – and the two lists are not interchangeable.
- The Master exam’s content, by rule, covers accepted codes, standards, and practices for installing and servicing HVAC systems plus the law and regulation relating to the HVAC business: business content is embedded in the one sitting, with no separate business exam.
- The examination fee is $150 for Master and $50 for Journeyman, paid to the Kentucky State Treasurer with the exam application. The license fee is $250 for a 12-month Master license ($50 Journeyman), prorated on initial issuance by birth month; renewal is annual, and results and scheduling run through the Department (exams are scheduled regionally by application volume).
- Master eligibility takes 2 years at the qualifying level by any of three routes: as a journeyman under a Kentucky master, as an out-of-state master or equivalent, or as a licensed mechanical engineer. One year of experience means at least 1,500 hours in a continuous 12-month period. Insurance runs $500,000 general liability plus $300,000 property damage, and continuing education is 6 hours a year.
How the practice program works
The full practice exam draws 100 questions on a 180-minute practice clock – Kentucky publishes the 70% passing standard but no question count or time limit, so the draw and the clock are this program’s practice convention – spanning the bank’s 19 topics, and every attempt draws a fresh assortment, so no two practice exams are the same.

Questions
Which Kentucky license does this cover?
The Master HVAC Contractor license – the practice exam is built to the Master exam’s published frame: its two references (NFPA 54 2009, IMC 2015), its embedded business content, and its 70% standard. Journeyman candidates study from a different reference list (the IRC 2015 replaces the IMC), so this program does not claim to mirror the Journeyman sitting.
Is the practice exam timed like the real one?
The full practice exam runs 100 questions on a 180-minute practice clock. Kentucky publishes the passing standard (at least 70%) but no question count or time limit for its exams, so this clock is our practice convention, not a mirror of a published format. The real exams are open book and are given in person by the Department, with results sent by mail.
Are these real exam questions?
No. Every question is original to PassProfessor, written from Kentucky’s published licensing law, rules, and examination requirements. Nothing here is copied or paraphrased from a licensing exam or a competitor’s bank.
What does the 70% benchmark mean?
Our practice exam is scored against a 70% practice benchmark, set to mirror the Department’s published passing standard of at least 70% for the Kentucky HVAC examinations. PRACTICE BENCHMARK ONLY — your score here is a study signal, not a result on the real exam.
