Florida HVAC Exam Prep: 1,500 Practice Questions for the Mechanical and Air-Conditioning Trade Knowledge Exams
PassProfessor’s Florida HVAC Exam Prep is built for candidates for Florida’s Mechanical Contractor and Class A / Class B Air-Conditioning Contractor licenses. The bank holds 1,500 original practice questions: a 1,250-question HVAC core covering the trade itself, plus 250 Florida questions on Florida licensing law and the Florida Building Code — Mechanical.
This product covers the Trade Knowledge examination. Florida also requires most contractor candidates to pass a separate Business and Finance examination; that exam is not covered by this product.
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
- Trade Knowledge is computer-based, administered under the Department of Business and Professional Regulation’s July 2024 Candidate Information Bulletin. Mechanical Contractor and Class A Air-Conditioning Trade Knowledge: 130 scored questions, 7.5 hours. Class B Trade Knowledge: 80 scored questions, 5 hours.
- Passing is 70%, and scores are not rounded up.
- The mechanical reference is the Florida Building Code — Mechanical, 2023 (8th Edition), which rests on the 2021 International Mechanical Code, together with the Florida Building Code — Energy Conservation.
- Certified licenses are issued by the Construction Industry Licensing Board under Chapter 489, Part I, Florida Statutes, and Rule 61G4, Florida Administrative Code. Registered licenses are issued by a local jurisdiction and recorded with the state board.
- Class A contractors may work on systems of any tonnage. Class B is capped at 25 tons of cooling or 500,000 Btu of heating in a single system. Mechanical contractors may work on systems of any tonnage and horsepower.
- Business and Finance is a separate examination. It is not covered by this product.
How the practice program works
The full practice exam draws 130 questions across all 18 topics in proportion to the bank — the same length and 7.5-hour allowance as the Mechanical and Class A Trade Knowledge exams — and every attempt draws a fresh assortment, so no two practice exams are the same.

Questions
Does this cover the Business and Finance exam?
No. This product covers the Trade Knowledge examination only. Florida requires most contractor candidates to pass both Trade Knowledge and a separate Business and Finance examination, and you will need separate preparation for Business and Finance.
Which licenses does the Trade Knowledge bank serve?
Mechanical Contractor, Class A Air-Conditioning Contractor, and Class B Air-Conditioning Contractor candidates. Certified and registered candidates take the same Trade Knowledge content.
Are these real exam questions?
No. Every question is original to PassProfessor, written from the published exam content areas and the cited references. Nothing here is copied or paraphrased from a licensing exam or a competitor’s bank.
What does the 70% benchmark mean?
