Hawaii C-52 HVAC Exam Prep: 1,450 Practice Questions for the C-52 Ventilating and Air Conditioning Contractor Exams
PassProfessor’s Hawaii C-52 HVAC Exam Prep is built for candidates for Hawaii’s C-52 Ventilating and Air Conditioning Contractor classification, licensed by the Contractors License Board. The bank holds 1,450 original practice questions: a 1,250-question HVAC core covering the trade itself, plus 200 Hawaii questions on Hawaii contractor law, business and law, exam administration, and C-52 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
- In Hawaii the license issues to the contracting entity or sole proprietor, not to an individual tradesperson: the business is qualified by a responsible managing employee (RME) who holds the experience and sits the examinations. The C-52 classification covers ventilating and air conditioning work, including heat pumps, solar heating and cooling systems, and controls other than electrical work.
- The contractor examinations run in two written parts – Part I Business & Law, common to all classifications, and Part II Trade, specific to the classification – and Hawaii’s rule (HAR 16-77-44) sets the minimum passing grade at 75% on each part.
- The Board approves the application before a candidate registers with PSI (the exam vendor since January 2023), and both parts must be passed within 6 months or a new application is filed. Experience runs 4 years of supervisory experience within the past 10 years, supported by at least 3 notarized experience certificates and a project list.
- There is no journeyman HVAC license in Hawaii – journey-worker licenses exist only for electricians and plumbers. The handyman exemption tops out at $1,500 of labor and materials combined per project.
- Contractor licenses renew every 2 years, by September 30 of even-numbered years, and Hawaii imposes no continuing-education requirement on contractor licensees. Insurance minimums run $100,000/$300,000 bodily injury and $50,000 property damage.
- Hawaii has no statewide mechanical code – the counties adopt their own – so this program keys no code edition for the C-52 exam, and none of the figures vendor sites attach to the Hawaii exams (per-part counts, minutes, or fees) are stated in the Board’s own published materials.
How the practice program works
The full practice exam draws 100 questions on a 180-minute practice clock – Hawaii’s published materials state no part counts or time limits, so the draw and the clock are this program’s practice convention – spanning the bank’s 20 topics and weighted across them, and every attempt draws a fresh assortment, so no two practice exams are the same.

Questions
Which Hawaii license does this cover?
The C-52 Ventilating and Air Conditioning Contractor classification, held by a contracting entity or sole proprietor through its responsible managing employee. Hawaii’s separate C-40 Refrigeration Contractor classification has its own PassProfessor program; the two share the Hawaii law and business coverage but carry different trade banks.
Is the practice exam timed like the real one?
The full practice exam runs 100 questions on a 180-minute practice clock. Hawaii’s published materials do not state the examination parts’ question counts or time limits, so this clock is our practice convention; what Hawaii does publish is the standard your score is measured against – 75% on each part.
Are these real exam questions?
No. Every question is original to PassProfessor, written from Hawaii’s published licensing law, Board rules, and the trade’s standard references. Nothing here is copied or paraphrased from a licensing exam or a competitor’s bank.
What does the 75% benchmark mean?
Our practice exam is scored against a 75% practice benchmark, set to mirror Hawaii’s published standard of 75% on each part of the contractor examinations (HAR 16-77-44). PRACTICE BENCHMARK ONLY — your score here is a study signal, not a result on the real exam.
