ExploreAbout this exam
The Florida air conditioning contractor license is a state credential that allows a business to advertise, bid, permit, and perform HVAC work in Florida. Florida issues air conditioning contractor licenses in three classes - Class A (unlimited within the trade), Class B (limited to units of a stated capacity), and Class C (limited to smaller units and specified work) - and each class carries its own scope, so confirm which class you are applying for before you build a study plan. The credential suits experienced installers, service technicians, and sheet-metal or mechanical tradespeople who are ready to move from working on crews to running contracts, pulling permits, and carrying responsibility for code compliance and jobsite safety. The examination is typically split into two parts: a trade section covering load calculations, equipment selection and start-up, duct design and air distribution, refrigeration and refrigerant handling, electrical controls and motors, and safety/environmental rules; and a business and financial management section covering contracts, liens, estimating, insurance, taxes, and employment obligations. Florida-specific material - the Florida Building Code, the Florida Energy Code, and the contractor licensing statutes - runs through both parts. Preparation means working from the current official candidate information bulletin, reading the adopted codes with tabs and index practice, and drilling calculations until they are fast and repeatable.
What you'll study
About FL HVAC preparation
What does the exam actually look like on test day?
It is a computer-based, multiple-choice examination delivered at a testing center, divided into a trade-specific portion and a business and financial management portion. The official candidate information bulletin published by the state licensing authority and its testing provider lists the current structure, so read that document before scheduling.
How many questions are on it, and how long do I get?
Those figures are set by the state and can change between bulletin revisions, so they are not reproduced here. The current question count, time allowance, and any scheduled breaks are published on the licensing authority's website and in the candidate information bulletin issued by the testing vendor.
What score do I need to pass?
The passing score is established by the licensing authority and is published in the official candidate information bulletin. Because it can be revised, check the authority's website for the figure in force on your test date rather than relying on what other candidates tell you.
Is it an open-book exam?
Florida contractor examinations are generally built around the idea that you know how to use the code books, and the bulletin specifies which bound references may be taken into the testing room. Confirm the approved list for your exam and class, and tab and index your books in advance.
How hard is the HVAC contractor exam?
Candidates usually find the trade portion manageable if they work in the field, and the business and financial portion harder, because it covers contracts, liens, estimating, insurance, and employment rules that technicians rarely touch. The code and calculation questions reward speed and familiarity more than memorization.
What if I fail - can I retake it?
Retake rules, waiting periods, fees, and any limits on attempts are set by the licensing authority and published in its candidate bulletin and on its website. Check there for the current policy before you assume a timeline, and use the score report to see which content areas cost you points.
What order should I study in?
Start with the Florida Building Code and contractor statutes, because they frame everything else. Then move to load calculations and system sizing, duct and air distribution design, equipment selection and start-up, and refrigerant handling. Finish with electrical controls and motors, and treat business and finance as a separate subject that needs its own time.
Why do so many candidates struggle with the business section?
It covers material with no field equivalent: lien law deadlines, contract requirements, workers' compensation and liability coverage, payroll and employment obligations, and financial statements. Candidates who spend all their study hours on equipment and ductwork routinely lose points here.
How much preparation time should I plan for?
Plan a schedule of several weeks of consistent study rather than a few cram sessions, and schedule your test date after you can complete calculation problems and code lookups without hesitation. Your own field background determines how much of the trade section you can move through quickly.
Does this page or site have any official connection to the exam?
No. This is independent study material prepared for candidates; it is not affiliated with, endorsed by, or approved by the licensing authority or the testing vendor. Always treat the official candidate information bulletin and the state's website as the controlling source for rules, forms, and figures.
