To get a Florida HVAC license you need four years of qualifying experience, then you register with Professional Testing, Inc. and pass two open-book exams (the AC trade knowledge exam and the Business & Finance exam, 70% each). You must also prove financial responsibility (FICO 660+ or a 14-hour course), carry insurance, and file an application with the DBPR including fingerprints and fees. You must be at least 18.
Before you start: which license do you need?
Air conditioning contractor licensing in Florida is governed by Chapter 489, Florida Statutes, and Rule 61G4, Florida Administrative Code, and is issued by the Florida Department of Business and Professional Regulation (DBPR) through the Construction Industry Licensing Board (CILB). The first decision is which class of license to pursue. A Class A air conditioning contractor can work on systems of unlimited capacity, while a Class B contractor is limited to 25 tons of cooling and 500,000 BTU of heating per system. It also helps to understand the difference between being certified (a statewide license that lets you work anywhere in Florida) and being registered (local competency that is limited to the jurisdiction that granted it).
Step 1: Get the qualifying experience
You need four years of qualifying experience in the trade. Florida allows combinations of education and experience to satisfy this requirement, so college coursework or a relevant degree can count toward part of the four years. Document your work history carefully, because the DBPR application requires you to verify it. If you are still building hours, this is the time to keep records of the projects and roles that demonstrate you have the breadth of experience the board expects.
Licensing requirements change. Always confirm the current experience, exam, and application rules directly with the DBPR before you apply, since fees, forms, and acceptable references are updated periodically.
Step 2: Register and apply to sit the exams
Once your experience is in order, you register and apply with Professional Testing, Inc., the vendor that administers the Florida air conditioning contractor examinations. You then schedule and pass both of the following:
- AC trade knowledge exam — the technical portion covering HVAC systems, installation, the building code, and safety. It is open book and requires 70% to pass.
- Business & Finance exam — a separate open-book exam covering contracting business practices, accounting, Florida lien law, and project management. It also requires 70% to pass.
Both exams are open book, but that does not make them easy. The candidates who pass are the ones who have practiced finding answers quickly under time pressure. Drill with a full-length Florida HVAC practice test, review targeted exam questions by topic, and follow our guide on how to pass the Florida HVAC exam the first time.
Step 3: Meet the financial responsibility and insurance requirements
Florida requires applicants to demonstrate financial responsibility. You can satisfy this in one of two ways: by having a FICO credit score of 660 or higher, or by completing a 14-hour board-approved financial responsibility course. If your credit is below the threshold, the course is a straightforward route to qualify.
You must also carry insurance before the license is issued. The minimums are general liability coverage of $100,000 and property damage coverage of $25,000. Line up your policy early so it does not hold up the final approval of your application.
Step 4: Submit your DBPR application
With your experience verified, both exams passed, financial responsibility met, and insurance in place, you submit your application to the DBPR. The application package includes the required fees, fingerprints and a background check, and proof of the items above. You must be at least 18 years old. Review the full Florida HVAC license requirements so nothing in your package is missing, because incomplete applications are the most common reason for delay.
After your license is issued, it renews on a biennial cycle and you must complete continuing education to keep it active. Wondering how hard the exams really are? See our breakdown of the Florida HVAC exam pass rate and what separates candidates who pass from those who have to retake.
That is the whole path: experience, exams, financial responsibility, insurance, and the DBPR application. Each step is manageable on its own, and most applicants find the exams are the part where good preparation makes the biggest difference. Our library includes hundreds of practice questions covering both the trade and business portions, available for $49 or $89 depending on the plan.
