What Is a Florida Air Conditioning Contractor License?
A Florida air conditioning contractor license is a state-issued credential that authorizes you to install, maintain, repair, fabricate, alter, extend, or design HVAC systems in the state. It is governed by Chapter 489 of the Florida Statutes and administered by the Construction Industry Licensing Board (CILB) under the Department of Business and Professional Regulation (DBPR).
In practical terms, holding an Air A or Air B license means you can bid HVAC work, sign contracts, pull mechanical permits, and legally collect payment. Without it, you cannot advertise HVAC contracting services, and you cannot enforce a contract in court if a customer refuses to pay. It is the difference between being a technician on somebody else's payroll and being the qualifier whose name is on the permit.
Florida's air conditioning license hierarchy is short and it matters:
Class A Air-Conditioning Contractor (Air A) — unlimited scope. Any system, any tonnage, any BTU capacity. This is the top of the HVAC ladder in Florida and the license that opens commercial and industrial work.
Class B Air-Conditioning Contractor (Air B) — the same categories of work, capped at 25 tons of cooling and 500,000 BTU of heating in any one system. Built for residential and light commercial.
Other Division Two trades (electrical, plumbing, roofing, pool/spa) operate under separate sections of Chapter 489 and do not authorize air conditioning work.
Both Air A and Air B are state-certified licenses, which means one credential covers all 67 counties. You are not filing a separate local competency registration every time you follow a job into a new jurisdiction.
Florida HVAC License Types — Choosing Your Scope
Florida issues two air conditioning contractor classifications. Each has its own scope, its own exam, and its own ceiling on the size of system you are permitted to touch. Picking the right one is the most consequential decision in the licensing process, and most contractors find the extra study time for Air A pays back many times over in business flexibility and earning potential.
Class A Air-Conditioning Contractor (Air A) ★ RECOMMENDED
ScopeUnlimited — HVAC, refrigeration, heating, ventilation, duct & piping
System LimitNo tonnage or BTU cap
Exams Required2 exams (Trade Knowledge + Business & Finance)
Experience4 years minimum, or approved combination
Avg. Study Time8–12 weeks
Earning Potential$75K–$200K+/year
License CoverageStatewide (all 67 counties)
Class B Air-Conditioning Contractor (Air B)
ScopeHVAC, refrigeration, heating, ventilation, duct & piping within Class B limits
System Limit25 tons cooling / 500,000 BTU heating per system
Exams Required2 exams (Trade Knowledge + Business & Finance)
Experience4 years minimum, or approved combination
Avg. Study Time6–10 weeks
Earning Potential$60K–$150K+/year
License CoverageStatewide (all 67 counties)
Recommendation: The Air A license is the most flexible HVAC credential in Florida. No tonnage cap means you can bid the 60-ton rooftop, the chiller replacement, the school, the hospital wing. If you already hold Air B, Florida allows an upgrade pathway to Air A with reduced experience requirements. Everything you need for the upgrade is in the Air A collection.

What a Florida Air A or Air B License Lets You Do
The scope of a Certified Air Conditioning Contractor license under Florida law is broad. Holders are authorized to:
• Install, maintain, repair, fabricate, alter, extend, or design central air conditioning, refrigeration, heating, and ventilating systems
• Perform duct work connected to a complete HVAC system, including duct cleaning and equipment sanitizing when the system must be partially disassembled
• Install, alter, or design piping, and the insulation of pipes, vessels, and ducts
• Work on low-voltage HVAC control wiring, and replace, disconnect, or reconnect dedicated HVAC electrical components within the limits Florida law allows
• Install condensate drains from air conditioning units to approved disposal points
• Perform incidental excavation related to HVAC work
• Pull mechanical permits in any of Florida's 67 counties without applying for separate local credentials
The dividing line between the two classifications is capacity. Class B stops at 25 tons of cooling and 500,000 BTU of heating in any one system. Class A has no ceiling. Large commercial systems, industrial facilities, major refrigeration work, multi-family towers, hospitals, and schools all sit above the Class B limit, which means only a Certified Class A Air Conditioning Contractor can sign for them.
5 Steps to Your Florida HVAC Contractor License
Over 100,000 contractors have used this process to get licensed with 1 Exam Prep. Most complete it in 3 to 6 months.
1
STEP 1: Verify Your Eligibility & CILB Requirements
Before you spend a dollar on books, confirm you meet Florida's HVAC contractor requirements. CILB requires you to be 18 or older with sufficient trade experience or education.
- Option A: 4 years of HVAC trade experience
- Option B: 4-year construction-related degree plus 1 year of applicable experience
- Option C: Combination of accredited college credits and field experience
- Option D: Qualifying military HVAC or mechanical experience
- Option E: Hold an active related Florida HVAC classification (upgrade path)
- Financial stability: credit report with a FICO-derived score required. Below the board's threshold means a surety bond or a financial responsibility course.
2
STEP 2: Prepare for Your Exams
The most critical step. Florida HVAC exams are open-book, which is not the same as easy. Passing depends on knowing which reference holds the answer and finding it before the clock runs out. Start 6 to 12 weeks before your test date.
- Enroll in an Air A or Air B exam prep course, online or instructor-led
- Get professionally highlighted and tabbed reference books
- Study both exam parts: Trade Knowledge and Business & Finance
- Take timed practice exams to simulate real testing conditions
- Learn open-book test-taking strategy and book navigation drills
- Browse the Air A collection or the Air B collection for the full study system
3
STEP 3: Register with Pearson VUE
Florida contractor exams are administered through the DBPR-approved process and Pearson VUE at testing centers statewide. You can schedule the two parts in any order and take them on separate days.
- Apply for exam eligibility, receive approval, then create your Pearson VUE account
- Both exams are open-book — you must bring the approved reference materials
- Score 70% or higher to pass each part
- Failed parts are retakable; passed scores stay valid toward licensure for a limited window
- Verify your book editions are current before test day. A complete set from the Air A or Air B collection removes the guesswork.
4
STEP 4: Submit Your Application to the DBPR
After passing your exams, submit your application to CILB through the DBPR. Incomplete or incorrect applications are the most common reason a candidate who already passed is still waiting months later.
- Complete the DBPR application with all required documentation
- Include proof of HVAC experience and employer verification forms
- Submit credit report and fingerprint results
- Pay the application fee and provide business qualification info if qualifying a company
- Review typically takes 4 to 8 weeks after submission
5
STEP 5: Complete Insurance Requirements
Once approved, obtain the required insurance before your license is activated. This is the final gate before you can legally contract.
- Public liability insurance at CILB minimum coverage
- Property damage insurance, required for all licensed contractors
- Workers' compensation if you have employees, or a valid exemption if eligible
- Submit proof of insurance to the DBPR
- License activated — you can begin contracting

Requirements for a Florida HVAC Contractor License
The requirements are set by the CILB and are uniform statewide for certified contractors. To qualify for an Air A or Air B license, you must satisfy one of the approved paths below.
| Path | Work Experience | Education Credits | Total |
|---|---|---|---|
| Path 1 | 4 years HVAC trade experience | None required | 4 years |

Inside the Florida Air A and Air B Exams
Both classifications require two separate exams. Knowing what is on each one, and which book holds the answer, is the whole game.
| Exam | Format | What It Covers | Prep Products |
|---|---|---|---|
| Air A Trade Knowledge | Open-book, multiple choice, 70% to pass | Unlimited-capacity system design, refrigeration, mechanical and fuel gas code, piping, controls, ventilation, load calculations, safety | Air A books & course |
| Air B Trade Knowledge | Open-book, multiple choice, 70% to pass | Same core topics scoped to 25 tons cooling and 500,000 BTU heating, residential and light commercial focus | Air B books & course |
| Business & Finance | Open-book, multiple choice, 70% to pass | Florida Contractor Manual, contract law, lien law, estimating, job costing, payroll, financial statements, tax and risk management | Included in both Air A and Air B packages |
Candidates routinely underestimate Business & Finance because it is not the trade they know, and it is the exam most often failed on the first attempt. Every Ultimate package in both collections includes Business & Finance prep for exactly that reason.

Certified vs. Registered: Going Statewide
Florida offers two license classes. We strongly recommend Certified for maximum earning potential and business growth.
| Feature | Certified (Recommended) | Registered |

| Exam | State Pearson VUE exams | Local competency exam |

Florida Air A & Air B Contractor License FAQ
Air A is the unlimited Florida air conditioning contractor license. It allows work on HVAC, refrigeration, heating, ventilation, duct, piping, and related systems of any size or capacity. Air B covers the same categories but is limited to systems up to 25 tons of cooling and 500,000 BTU of heating in any one system. Prep for each in the Air A collection or the Air B collection.
Choose Air A if you want maximum flexibility, commercial opportunities, large-system work, or long-term business growth. Choose Air B if you plan to focus on residential and light commercial HVAC within the Class B capacity limits. If you are unsure, look at the jobs you are currently turning down.
Meet the DBPR and CILB eligibility requirements, prepare for your exams, pass the Air A or Air B Trade Knowledge exam, pass the Business & Finance exam, submit your application, complete fingerprinting and credit requirements, and provide proof of insurance. The full process typically takes 3 to 6 months.
Florida generally requires four years of experience or an approved combination of education and experience. Some upgrade paths may reduce the required experience if you already hold an active Florida HVAC classification.
Yes. Florida construction contractor exams are open-book, multiple-choice exams. You must use approved references and know how to find information quickly during the exam. Pre-tabbed and pre-highlighted book sets from the Air A and Air B collections are the fastest way to navigate them under time pressure.
Yes. Air A and Air B candidates must pass both the trade exam and the Business & Finance exam. It is included in every Ultimate exam prep package.
Most candidates budget $1,500 to $5,500 or more depending on exam prep, books, application support, credit report, fingerprinting, DBPR fees, and insurance. Online courses start at $79 and complete Ultimate rental packages run up to $4,099. Financing is available.
The Air A trade exam draws from the Florida Building Code Mechanical, Fuel Gas, and Energy Conservation volumes, ACCA Manual J, Manual D, and Manual N, refrigeration and HVAC systems references, OSHA 29 CFR 1926, and the Florida Contractor Manual. Complete tabbed and highlighted sets are available in the Florida Air A Contractor collection.
Most Air B candidates study 6 to 10 weeks and most Air A candidates study 8 to 12 weeks, at roughly 8 to 12 hours per week. Candidates using pre-tabbed and pre-highlighted books usually shorten that timeline because their study hours go into practice questions instead of marking up books.
Both options exist. Purchase sets are yours permanently and stay useful as a jobsite code reference after you pass. Rental packages lower your upfront cost and suit candidates who only need the books through exam day. Compare both in the Air B collection and the Air A collection.
