How to Get an HVAC License in Florida

If you’re doing HVAC work in Florida and the contract has your name on it, you need a contractor license. The guy turning wrenches under you can work under your license. But if you’re bidding the job, signing the contract, and pulling the permit, the licensing responsibility falls on you.

Florida licenses HVAC contractors through the Department of Business and Professional Regulation (DBPR). You’ll need qualifying experience, state exams, financial documentation, and insurance. You’ll also need to choose the right license class.

A Class B license can cover plenty of residential and smaller commercial work. One oversized rooftop unit, though, and you’re outside its limits.

Do You Need an HVAC License in Florida?

Florida requires the appropriate contractor license to independently contract for regulated HVAC work, unless a statutory exemption applies.

Technicians working under an appropriately licensed contractor don’t need their own state contractor license for that work. They may still need federal certification to handle refrigerants.

The EPA’s Section 608 rules require certification for technicians performing work that could release regulated refrigerants. Apprentices are exempt while closely and continually supervised by a certified technician.

There are four certification types:

• Type I: Small appliances.
• Type II: High- and very-high-pressure appliances, excluding small appliances and motor vehicle air conditioners.
• Type III: Low-pressure appliances.
• Universal: All equipment types covered by Section 608.

Section 608 certification doesn’t expire. You’ll need the appropriate Florida contractor authorization if you want to take regulated HVAC contracts independently.

Florida HVAC License Classes: Class A, Class B, and Mechanical

The equipment you plan to install determines which license class you’ll need.

Florida defines each classification in Section 489.105.

Class A: Larger Systems and Broader Work

Class A contractors can work on HVAC systems without the capacity restrictions imposed on Class B licenses. Their scope also includes boiler and unfired pressure vessel systems, pressure and process piping, and pneumatic control piping.

For contractors moving into larger commercial installations, those additional systems can make a difference in which jobs they’re allowed to bid.

Class B: Residential and Smaller Commercial Systems

Class B contractors are limited to systems with no more than 25 tons of cooling and 500,000 Btu of heating in any one system.

Say a building has two separate 20-ton rooftop units. Both fall within the cooling-capacity limit. One 30-ton unit exceeds it.

The restriction applies to each system. A building can have multiple systems within the Class B limit, provided the work stays within the rest of the license’s scope.

Mechanical: When the Work Goes Beyond HVAC

A mechanical contractor license covers additional mechanical systems, including liquefied petroleum gas lines and natural gas fuel lines within buildings.

Class A and Class B air-conditioning contractors can disconnect or reconnect qualifying gas appliance changeouts. Installing new gas fuel lines inside a building falls outside their scope.

Replacing a furnace and running new gas piping across a commercial building are different jobs. Check the license scope before quoting both.

What About Condensate Drains?

Florida’s Class A and Class B scope includes installing condensate drains from air-conditioning units to an existing safe waste or other approved disposal, excluding direct connections to sanitary systems.

That’s useful on changeouts where the drain needs to be rerouted. The statutory limits still apply.

What About Class C? Florida closed the Class C air-conditioning classification to new applicants after October 1, 1988. Contractors who qualified under the existing classification can continue to hold it.

Certified vs. Registered HVAC Licenses

A certified license lets you take jobs across Florida within your classification. A registered license limits you to the jurisdiction covered by your registration.

Planning to expand into neighboring counties? Statewide certification gives you room to do that without the geographic restriction of a registered license.

Florida HVAC License Experience Requirements

Florida’s standard experience-only pathway requires four years of qualifying experience, including at least one year as a foreman.

Approved combinations of college education and field experience can also qualify.

The work must be relevant to the license classification you’re applying for. DBPR’s Class A application instructions explain the experience pathways and documentation.

Can a College Degree Exempt You From the Trade Exam?

Yes, under a specific exemption. Applicants with a bachelor’s degree in building construction from an accredited four-year college and a GPA of at least 3.0 can qualify for exemption from the trade knowledge examination.

The Business and Finance examination still applies.

DBPR explains the exemption in its construction examination application packet.

Document Your Work History Before Applying

DBPR requires employment and experience records. Get these together early:

• Employer names, addresses, and contact information
• Dates of employment
• Employer contractor license numbers
• Worker and foreman experience
• Applicable college transcripts

If you’ve worked for several HVAC shops, this can take longer than expected.

Don’t wait until you’ve passed the exam to discover that a former employer closed three years ago.

How to Get an HVAC Contractor License in Florida

Step 1: Choose Your License Class

Decide whether your work requires Class A, Class B, or mechanical certification.

Think about the jobs you want to bid next year, not just the equipment you’re servicing today. A Class B license may cover your current work while limiting the larger contracts you want to pursue.

Step 2: Verify Your Qualifying Experience

Match your work history and education against DBPR’s requirements.

Complete the experience forms for your classification. Check employment dates, foreman experience, and supporting records before submitting anything.

Missing documentation can delay approval.

Step 3: Register for the State Exams

Florida uses Professional Testing, Inc. to register construction examination candidates. Once approved, you’ll schedule your computer-based examinations through Pearson VUE.

Apply through Professional Testing. DBPR’s construction examination page explains registration and scheduling.

Step 4: Pass the Trade and Business and Finance Exams

Certified Class A, Class B, and mechanical applicants take the applicable trade examination and Business and Finance examination, unless they qualify for an exemption.

DBPR lists the question counts and time limits in its Examinations at a Glance. The exams are open book. You’ll still need to know where to find answers quickly.

The trade exam tests your knowledge of the work covered by your license. Business and Finance covers contracts, accounting, and the business responsibilities of a licensed contractor.

Don’t spend every study session on equipment and ductwork. Knowing how to diagnose a bad compressor won’t help much with a question about financial statements.

DBPR publishes the approved examination reference lists. Bring only the materials permitted for your exam.

Step 5: Prepare Your Financial Documentation

Florida requires active certified contractor applicants to demonstrate financial responsibility and stability.

You’ll need a credit report with a FICO-derived score, along with the required public-records information.

DBPR’s Class A application instructions require applicants with a credit score below 660 to provide proof of completing a board-approved 14-hour financial responsibility course.

That course is separate from the continuing education required when you renew your license.

Step 6: Submit Your Application and Fingerprints

Once you’ve passed the required examinations, complete the appropriate DBPR certification application.

You’ll need your experience records, financial documents, electronic fingerprints, and application fee. Submit your license application before submitting fingerprints, as DBPR’s business qualification checklist requires.

If you’re licensing a business entity, use the application for a contractor qualifying a business. DBPR provides separate application pathways for individual certification and business qualification.

Step 7: Meet Insurance Requirements

DBPR’s business qualification application lists these minimum coverage amounts for Class A and Class B air-conditioning contractors:

• $100,000 in public liability
• $25,000 in property damage

You’ll also need to address workers’ compensation coverage or an exemption.

Those amounts satisfy the stated licensing minimums. Your actual insurance needs may be higher, especially for commercial contracts.

Confirm your license is active before taking regulated HVAC contracts.

How Much Does an HVAC License Cost in Florida?

Budget $295 to sit the two required HVAC examinations once, based on the fees in DBPR’s construction examination application packet.

The $135 Professional Testing registration fee is mandatory each time you register for an examination part. Retakes can add to the bill.

How Many Times Can You Retake the Exams?

DBPR allows unlimited examination attempts within a four-year period beginning with your first scheduled examination.

You’ll pay the required registration and examination charges again when retaking an examination.

There’s also a separate deadline: You must obtain your certified license within four years of receiving your qualifying examination score.

Two clocks. One governs how long you have to pass the exams. The other governs how long you have to complete licensing after your qualifying score.

Initial License Application Fees

DBPR’s Class A and Class B individual certification applications list the same initial fee schedule.

For applications submitted between May 2026 and August 2027, the listed initial fee is $245.

Your full cost may also include fingerprints, a credit report, insurance, and any examination preparation or financial responsibility courses you need.

Use DBPR’s official examination application packet and the Class A application to check fees before paying.

How Long Does It Take to Get an HVAC License in Florida?

Starting from scratch, the standard experience-only route takes four years. Approved education-and-experience combinations can provide another route.

If you’ve already met the qualifications, the remaining time depends on examination scheduling, experience verification, fingerprint processing, and DBPR’s application review.

Starting an HVAC Business in Florida

If you’re taking HVAC contracts through an LLC or corporation, the business needs to be properly qualified under Florida’s contractor licensing rules.

DBPR has a specific Certified Air Conditioning Contractor Qualifying a Business checklist for Class A and Class B contractors.

Before signing jobs under the company name, make sure the business qualification, insurance, workers’ compensation obligations, and permits are in order.

Florida also licenses other construction trades separately. An HVAC license has limits when a job crosses into electrical, plumbing, or general contracting work.

Our guides cover Florida general contractor licensing, electrical contractor licensing, and plumbing contractor licensing.

What Electrical Work Can Florida HVAC Contractors Perform?

Florida allows Class A, Class B, and mechanical contractors to perform specified electrical work connected to HVAC systems.

Under Section 489.105, that includes:

• Replacing, disconnecting, or reconnecting power wiring on the line or load side of an existing dedicated disconnect switch on single-phase systems
• Repairing or replacing wiring, disconnects, breakers, or fuses for dedicated HVAC circuits, with proper circuit breaker locking
• Installing, disconnecting, and reconnecting low-voltage HVAC control wiring

Replacing a unit and reconnecting its existing dedicated electrical supply may fall within your scope. Rewiring unrelated building circuits requires separate authorization.

Check first. A changeout that needs major electrical alterations can involve work outside your HVAC license.

For the broader requirements, see our Florida electrical contractor license guide.

Florida HVAC License Renewal

Florida contractor licenses renew every two years.

Class A and Class B air-conditioning contractors generally need 14 hours of approved continuing education per renewal cycle.

The required subjects include:

• Specialized or advanced instruction
• Workplace safety
• Business practices
• Workers’ compensation
• Laws and rules
• Additional board-approved construction instruction

DBPR provides reduced continuing education requirements for certain first-time renewals.

Its Construction Industry renewal table lists a standard renewal fee of $205, plus $50 per qualified business. Check the amount on your renewal notice before paying.

Complete the required continuing education before your renewal deadline and confirm the hours have been reported to DBPR.

Put Your License Number on Your Paperwork

Florida’s Section 489.119 requires contractors to include their license number on each offer of services, business proposal, bid, contract, or advertisement, regardless of medium.

That includes the estimates you send customers. If your truck has business lettering, the contractor’s registration or certification number must also be conspicuously and legibly displayed with the lettering or artwork.

Keep required license information on your customer-facing documents and check it before sending. Cinderblock’s HVAC contractor software helps you keep estimates and invoices organized.

Cinderblock also keeps estimates, appointments, customer records, job photos, and invoices organized. On the Build plan, you can track employee time and job costs for longer installations.
