This is a complete Florida HVAC contractor exam study guide for the air conditioning Class A/B license — organized by content area, with the correct answer and a written explanation on every single question.

The Florida air conditioning trade exam is developed by Professional Testing, Inc. for the CILB and delivered as an open-book, multiple-choice test — the trade knowledge exam runs across two 65-question sessions, and every applicant must also pass a separate Business & Finance exam. You need 70% to pass each. Because it is open book, the candidates who pass are the ones who know the material well enough to find answers fast.
Every question maps to one of the 10 content areas, weighted the way the real exam is. The areas where most candidates lose points — and where you should spend extra time — are:
Work one content area at a time. Read the question, try to answer it before you look, then read the explanation — even on the ones you got right.

Our full study plan lays out the order step by step.
The first two content areas are free with no account. Full access unlocks all 10 areas and 341 explained questions. Remember the study guide prepares you for the exam — you still need your four years of qualifying experience and a passing score on both exams to get licensed.
