Kentucky HVAC Journeyman Exam Prep: 200 Practice Questions for the Journeyman HVAC Mechanic Exam
PassProfessor’s Kentucky HVAC Journeyman program prepares candidates for the Journeyman HVAC Mechanic license examination given by the Kentucky Department of Housing, Buildings and Construction (DHBC). Its 200 original practice questions are keyed to the two references the Department lists for the journeyman exam — the National Fuel Gas Code (NFPA 54, 2009 edition) and the International Residential Code (2015 edition) — and to the Kentucky licensing law and regulation in KRS 198B.650–198B.689 and 815 KAR 8:010.
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
- Licensing authority: the Kentucky Department of Housing, Buildings and Construction (DHBC), Division of HVAC, under KRS 198B.650–198B.689 and 815 KAR 8:010.
- The journeyman examination is the Department’s own in-person, open-book exam; the passing standard is at least 70% (815 KAR 8:010 § 4).
- Exam references as printed by the Department for the journeyman exam: National Fuel Gas Code (NFPA 54) 2009 edition and International Residential Code 2015 edition — no mechanical code volume is listed for this exam.
- Examination fee: $50, payable to the Kentucky State Treasurer with Form HVAC-4; results are reported by U.S. mail.
- Eligibility: at least 18 years old and two years of qualifying HVAC experience — one year means at least 1,500 hours of HVAC work in a continuous 12-month period — with up to one year satisfiable by an approved curriculum or professional training.
- A journeyman mechanic works under the supervision, direction, and responsibility of a master HVAC contractor, is physically on site, and personally observes and is responsible for each apprentice assigned to the journeyman.
- Initial license fee $50 for a 12-month license; renewal is $50 each year by the last day of the licensee’s birth month, with six hours of approved continuing education in the 12 months before renewal.
- A passing score stays valid for three years, and a passing master examination score may be applied to the journeyman examination requirement while it remains valid.
- The Department does not publish a question count, time limit, or content outline for this exam; this program’s practice draw and clock are PassProfessor practice conventions (see the benchmark note).
How the practice program works
The program pairs a timed 50-question practice exam — a fresh, blueprint-weighted, unseen-first draw on every attempt, so no two attempts are the same exam — with a drill for each of the 12 topics below, so a weak area can be worked on its own. The 50-question draw and the 120-minute practice clock are PassProfessor practice conventions: the Department does not publish a question count or a time limit for this exam.
The 200 questions divide across the trade and the Kentucky journeyman licensing rules as follows:
- Heating & Cooling Equipment — 16 questions
- Service Diagnostics & Calculations — 13 questions
- Installation, Clearances & Access — 10 questions
- Duct Systems & Airflow — 21 questions
- Combustion Air — 16 questions
- Exhaust & Venting — 23 questions
- Fuel-Gas Piping — 10 questions
- Controls, Electrical & Motors — 16 questions
- Refrigeration & Piping — 15 questions
- Furnace Operation, Testing & Safety — 18 questions
- Condensate & Hydronics — 12 questions
- Kentucky Journeyman Licensing — 30 questions

Questions
Is this the official exam?
No. This is a practice program built from the Department’s published framework for the journeyman examination. The real exam is the Department’s own in-person, open-book sitting, registered through DHBC on Form HVAC-4.
Which books does the journeyman exam use?
The Department lists exactly two references for the journeyman exam: the National Fuel Gas Code (NFPA 54), 2009 edition, and the International Residential Code, 2015 edition. No mechanical code volume is listed for this exam, and this program keys nothing to one.
How long does a passing score stay valid?
Three years. A score on the master HVAC contractor examination may also be applied to the journeyman examination requirement while it remains valid.
Does this program cover the master contractor exam?
No — it is built for the journeyman mechanic tier. The master examination carries a different reference list and an embedded law-and-regulation component; PassProfessor’s Kentucky HVAC program covers that tier.
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.
