How to Get Your HVAC License in Florida: Requirements, Exams, and Costs

Florida requires a state contractor license before you can pull a permit or run an HVAC business. Not a certification. Not a registration card. A full contractor license issued by the state's Department of Business and Professional Regulation — backed by a credit check, two exams, proof of insurance, and four years of documented field experience. Only a handful of states are this strict about it.

If you're working under someone else's license right now and planning to go out on your own, this is the process you're looking at. It's not fast — expect three to six months from application to approval — but it's doable if you go in with a clear picture of what's required.

This guide covers every step: license types, experience requirements, the two exams you'll need to pass, the financial checks, insurance minimums, and the full cost to get licensed.

Who Governs HVAC Licensing in Florida

The Florida Department of Business and Professional Regulation (DBPR) handles all contractor licensing through its Construction Industry Licensing Board (CILB). This is the body that sets requirements, reviews applications, administers discipline, and issues licenses.

The CILB website is at myfloridalicense.com. That's where your application goes, where you track its status, and where your license will eventually live once it's issued.

Florida Statutes Chapter 489 covers contractor licensing. If you want to read the actual law rather than a summary of it, that's where to look.

Two License Paths: State Certified vs. Registered

Before picking a license class, you need to understand the difference between certified and registered licenses. Most contractors working across Florida — or planning to — should go certified.

State Certified: You pass the state CILB exam and get licensed at the state level. This lets you work anywhere in Florida. One license, one renewal, no county-by-county paperwork.

County/Municipal Registered: You pass a local competency exam administered by your county or municipality. This license is limited to the jurisdiction that issued it. If you want to work in an adjacent county, you need to get registered there too.

Registered licenses typically cost less upfront — the application fee runs around $149 versus $309 for a certified license — but the geographic restriction is a real operational problem for most businesses. Almost every contractor who intends to grow eventually moves to a certified license.

This guide focuses on the State Certified path, since that's what most techs going out on their own are pursuing.

License Classes: Class A vs. Class B

Florida's air conditioning contractor license comes in two classes. The difference is the size of the systems you're allowed to work on.

Class A — Air Conditioning Contractor (Unlimited)

Class A has no capacity limit. You can install, maintain, repair, and replace commercial and residential HVAC systems of any size. This is what you need if you plan to work on large commercial buildings, industrial facilities, or any system above 25 tons cooling or 500,000 BTU heating.

The Class A trade exam is 130 questions with a 7.5-hour time limit.

Class B — Air Conditioning Contractor (Limited)

Class B caps you at 25 tons cooling and 500,000 BTU heating per unit. For most residential work and light commercial, this is sufficient — single-family homes, small retail spaces, small apartment buildings. If you stay in the residential market and don't plan to touch large commercial systems, Class B is an appropriate fit.

The Class B trade exam is 80 questions with a 5-hour time limit.

Both classes require the same Business and Finance exam. Both are available as certified (statewide) or registered (local). Both require the same four years of experience.

There is also a Mechanical Contractor license for systems exceeding those thresholds, but that license addresses industrial piping, boilers, and pressure vessels — a different scope than standard HVAC.

Experience Requirements

Four years of documented HVAC experience is the baseline. That experience has to be verified — meaning signed employer affidavits stating the dates you worked, the type of work you performed, and the systems you installed, maintained, or repaired.

At least one of those four years needs to involve supervisory or lead responsibilities. You don't have to have been a formal foreman, but you need to be able to document that you were directing work, not just following instructions.

Education can substitute for some experience. The formula is 60 classroom hours equals three months of experience credit. So if you completed an HVAC associate degree program, you may be able to count a portion of that toward the four-year requirement. The total experience still has to add up to four years with at least one year of actual field work.

If you were self-employed during some of this period, you can document that experience with customer contracts, invoices, and project records rather than employer affidavits.

The DBPR reviews experience documentation manually. Gaps in employment, ambiguous affidavits, or experience in a different trade can slow down or complicate the application. Be thorough when you put this together.

The Financial Responsibility Check

This is where a lot of applicants get surprised. Florida runs a credit check on every contractor license applicant.

The CILB requires a minimum FICO score of 660. If you're below that, you have two options:

1. Complete a DBPR-approved 14-hour financial responsibility course
2. Secure a surety bond (typically $500–$2,000 annually) as an alternative demonstration of financial responsibility

Your credit report also gets reviewed for unresolved judgments, liens, and bankruptcies. An open bankruptcy or an unpaid judgment can hold up your application even if your score is above 660.

Pull your credit report before you apply. If there are issues, address them or be prepared to explain them in writing to the board.

This check has nothing to do with your EPA 608 certification or your technical skills. It's about whether the state believes you can manage the financial responsibilities that come with running a contracting business.

Insurance Requirements

You need to have insurance in place before your license can be issued. The state minimums are:

• General Liability: $100,000 per occurrence / $300,000 aggregate
• Property Damage: $25,000 per occurrence
• Workers' Compensation: Required if you have employees

The certificate of insurance has to name the Florida Department of Business and Professional Regulation as the certificate holder. Your regular COI naming a customer won't satisfy this.

General liability at these minimums typically runs $800–$2,000 per year depending on your revenue and coverage history. Workers' comp varies significantly based on your payroll and job classification, but often exceeds $3,000 annually once you have employees on the books.

Many new licensees pay more than these minimums. The state minimums are low — most commercial customers and general contractors will require higher limits anyway.

The Exams

Every applicant for a State Certified HVAC license has to pass two separate exams. Both are administered by the DBPR's approved testing vendor. The current combined exam fee is $295 for both tests.

Trade Knowledge Exam

This covers refrigeration cycles and system components, electrical systems, ductwork design and installation, load calculations, refrigerant handling, safety requirements, and the 2021 Florida Building Code mechanical sections. Florida currently follows the 2021 International Mechanical Code (IMC) with state amendments.

• Class A: 130 questions, 7.5 hours
• Class B: 80 questions, 5 hours
• Passing score: 70%

Business and Finance Exam

This covers Florida lien law, contractor liability, workers' compensation law, payroll and taxes, insurance, contract law, and general construction business practices. It is open-book — you're allowed to bring approved reference materials.

• 120 questions
• 6.5 hours
• Passing score: 70%

The business and finance exam trips up a lot of technically skilled techs who underestimate it. The Florida lien law questions in particular are detailed. Exam scores are valid for four years, so if you pass one and need to retake the other, you won't lose the score you've already earned.

There are several approved Florida-specific exam prep courses that cover both tests. Gold Coast Schools in South Florida is one of the best-known providers; there are also online options. Spending $300–$500 on a structured prep course is worth it — the exams are not easy.

Step-by-Step: The Application Process

Here's the sequence from start to licensed:

Step 1: Verify eligibility Confirm you're 18+, have four years of verifiable experience including one supervisory year, and have no FICO issues you haven't addressed.

Step 2: Create an account on myfloridalicense.com All applications go through the DBPR's online portal.

Step 3: Submit your application and fee The certified contractor application fee is $309 (non-refundable). Upload all required documentation: experience affidavits, any education transcripts, credit authorization, and personal history information.

Step 4: Get fingerprinted Florida requires electronic fingerprinting through a DBPR-registered LiveScan provider. This is part of the mandatory background check.

Step 5: Receive exam eligibility notification Once the DBPR reviews your application and approves your eligibility, they'll notify you that you can register for the exams.

Step 6: Register for and pass both exams Pay the $295 exam fee and schedule your tests. You can take them in any order.

Step 7: Submit insurance certificates Once you've passed both exams, submit your certificates of insurance naming the DBPR as certificate holder.

Step 8: Submit financial responsibility documentation If your FICO is 660+, this is the credit report. If below 660, the financial responsibility course completion or bond documentation.

Step 9: Pay the license issuance fee An additional $205 fee is due when the license is issued.

Step 10: Receive your license The DBPR issues the license once all requirements are verified.

What It Actually Costs

Here's a realistic cost breakdown for a first-time applicant:

Insurance is on top of that. General liability at state minimums typically runs $800–$2,000 for year one. If you have employees, workers' comp adds considerably more.

Total first-year cost including insurance: expect $2,000–$3,500 or more depending on your insurance history and whether you need workers' comp.

Timeline: What to Expect

Three to six months is the realistic range from application submission to license in hand. The wide range reflects how well-prepared your application is.

DBPR processing of the initial application takes two to four weeks if everything is in order. Background checks run two to four weeks on top of that. Once you receive exam eligibility notification and pass both exams, the final review takes another one to three weeks.

Where applicants lose the most time: incomplete experience documentation, credit issues that require additional paperwork, and scheduling delays for the exams (particularly if testing centers are backed up).

Submit your application before you need the license. If you're planning to start a business in January, apply in July or August.

EPA 608 Certification

EPA Section 608 certification is a separate federal requirement that applies to anyone who handles refrigerants. This isn't issued by the DBPR — it's administered through EPA-approved testing organizations (ESCO Institute, Mainstream Engineering, and HVAC Excellence are the main ones).

You need 608 certification to legally purchase refrigerant and to perform any work involving refrigerant handling. Florida's contractor license application process assumes you already have it. If you don't, get it done first — it's a much simpler exam, costs $20–$50, and can typically be completed in a day.

If you're still early in your career and need to work through how to become a licensed HVAC technician, 608 certification is one of the first steps you should take regardless of where your career goes.

Reciprocity: The Short Answer

Florida's Construction Industry Licensing Board does not maintain formal reciprocity agreements with other states for HVAC contractor licenses. If you're moving from Georgia or Texas with an active contractor license, that license does not transfer.

Florida does have a limited endorsement pathway. If you've held an equivalent contractor license in another state for at least 10 years and that license is currently active, you may be able to apply for endorsement — which typically still requires passing Florida's Business and Finance exam but may waive the trade exam. Some reciprocity guidance exists for Alabama, Mississippi, and North Carolina through the CILB, but this is narrow and not broadly applicable to HVAC.

Assume you're starting fresh and plan accordingly.

Renewal: Every Two Years

Florida contractor licenses are renewed biennially. Certified contractors renew by August 31 of even-numbered years. Registered contractors renew by August 31 of odd-numbered years.

The renewal fee is $209. You also need 14 hours of continuing education from a board-approved provider before each renewal.

The 14 hours break down like this:

• 1 hour: Workplace safety
• 1 hour: Business practices
• 1 hour: Workers' compensation
• 1 hour: Laws and rules
• 1 hour: Wind mitigation
• Remaining hours: Elective topics from the approved list

In Miami-Dade County, the requirement is 16 hours rather than 14.

CE courses run $15–$100 per course depending on the provider and topic. Most contractors complete the full 14 hours through a single bundled package from one provider — online options are widely available and typically cost $79–$150 for the full renewal package.

Fail to renew on time and the license goes into delinquent status. You'll pay a late fee on top of the renewal fee to reinstate it.

Once You're Licensed

A Florida HVAC contractor license opens up the full residential and commercial market. It's also what Florida employers are hiring for — companies working on larger commercial projects typically require workers to come from licensed businesses, and the license is your ticket into that work.

The salary data for Florida reflects what the market is paying right now. If you're comparing the cost and effort of getting licensed against what your earnings look like on the other side, the numbers tend to make the case clearly.

Frequently Asked Questions

How long does it take to get an HVAC license in Florida?

Three to six months is the typical range from submitting your application to receiving your license. The main variable is how complete and clean your documentation is — missing experience affidavits or credit issues can add weeks to the timeline.

What is the difference between a Class A and Class B HVAC license in Florida?

Class A has no capacity limit and allows you to work on any size commercial or residential system. Class B is restricted to systems of 25 tons cooling or 500,000 BTU heating or less per unit, which covers most residential and light commercial work.

Do I need the EPA 608 certification to get a Florida HVAC contractor license?

EPA 608 certification is a separate federal requirement for anyone handling refrigerants. Florida's licensing process assumes you have it. Get your 608 before applying for the contractor license if you don't already have it.

What credit score do I need for a Florida HVAC contractor license?

The CILB looks for a minimum FICO score of 660. If you're below that, you can complete a DBPR-approved 14-hour financial responsibility course or secure a surety bond as an alternative.

How much does a Florida HVAC contractor license cost?

Licensing fees alone run approximately $809 before exam prep or insurance: $309 application fee, $295 exam fee, $205 issuance fee. Add $300–$500 for exam prep, $75–$100 for fingerprinting, and $50–$100 for a credit report. Total first-year cost including insurance is typically $2,000–$3,500 or more.

Can I transfer my out-of-state HVAC contractor license to Florida?

Florida does not have broad reciprocity agreements for HVAC contractor licenses. If you've been licensed in another state for 10+ years, you may qualify for endorsement — but most applicants need to go through the full Florida process. Plan to take at least the Business and Finance exam regardless.

How many hours of continuing education does Florida require for HVAC license renewal?

14 hours every two years for most of Florida. Miami-Dade County requires 16 hours. The renewal deadline is August 31 of even-numbered years for certified contractors. Required topics include workplace safety, business practices, workers' compensation, laws and rules, and wind mitigation.

What is the passing score for the Florida HVAC contractor exam?

Both the Trade Knowledge exam and the Business and Finance exam require a minimum score of 70% to pass. Exam scores are valid for four years, so if you pass one and need to retake the other, you won't lose the first score.
