The Construction Industry Licensing Board, part of Florida's Department of Business and Professional Regulation, licenses HVAC contracting statewide under Chapter 489. Contractors need a Certified or Registered Class A or B air-conditioning license, or a Mechanical contractor license, plus, for anyone handling refrigerant, separate federal EPA Section 608 certification.

Florida licenses heating, ventilation, air conditioning and refrigeration contracting at the state level. The agency is the Construction Industry Licensing Board, operating inside the Department of Business and Professional Regulation (DBPR). The board reviews license applications, sets fees by rule, holds disciplinary hearings, and writes the rules that implement Chapter 489 of the Florida Statutes, the law that governs construction contracting statewide. Florida uses two license statuses under this system. A certified license is issued by the state and lets the holder contract anywhere in Florida without meeting a second, local competency test. A registered license is issued after the holder first meets a local jurisdiction's competency requirement, and it only authorizes work inside that jurisdiction. Certified license numbers begin with the letter C, and registered numbers begin with the letter R, a pattern set out in the statute's definitions section. For HVAC and refrigeration work specifically, the board issues certified or registered licenses in several classes described later in this brief, covering everything from unlimited central air conditioning and heating work to narrower categories tied to tonnage or to servicing only. Anyone who wants to bid, contract for, or be paid for HVAC installation, repair, alteration, or design work in Florida needs one of these state licenses, held either individually or through a qualifying agent for a business organization. The board's own construction industry page is the primary place a contractor should start, since it lists every license type, the licensing forms tied to each, and links into the statute itself.
Florida's Construction Industry Licensing Board issues four license classes that reach HVAC work. A Class A air-conditioning contractor has unlimited scope to install, maintain, repair, fabricate, alter, extend, or design central air-conditioning, refrigeration, heating, and ventilating systems, plus the duct work needed to complete an air-distribution system, and boiler and unfired pressure vessel systems. A Class B air-conditioning contractor holds the same scope of work but is capped at 25 tons of cooling and 500,000 BTU of heating in any one system. Neither Class A nor Class B may run gas fuel lines, potable water lines, sanitary sewer lines, swimming pool piping, or electrical power wiring; that work has to go to a contractor licensed in those separate trades. A Mechanical contractor license (occupation code CM for certified, RM for registered) is functionally the same unlimited scope as Class A air-conditioning, covering central air-conditioning, refrigeration, heating, and ventilating systems including duct work, with the same carve-out against gas lines, water lines, sewer lines, pool piping, and electrical work. A contractor who wants to run all four trades listed above under one credential typically holds the Mechanical license rather than stacking narrower ones. Both the Class A/B and Mechanical definitions come directly from the Construction Industry Licensing Board's published license type descriptions, which track the statutory definitions in Chapter 489. Each class carries its own application, exam, and renewal path through DBPR, and a contractor's permits, contracts, and advertising must show the specific certification or registration number tied to whichever class was actually issued, not a different class the contractor also happens to hold.
Florida still lists a Class C air-conditioning contractor category, but it is not open to new licensees. The board's own definition states that a Class C license is limited to servicing air-conditioning, heating, or refrigeration systems, including duct cleaning and equipment sanitizing that requires at least a partial disassembly of the system, and that the certification or registration had to already be valid on October 1, 1988. The board's page adds a direct note: no person who was not already registered or certified as a Class C air-conditioning contractor as of that date may be registered or certified in that class after October 1, 1988. In practical terms, Class C is a grandfathered category for contractors who were servicing-only technicians before that cutoff and have kept the license active and renewed ever since. A contractor building a new HVAC business in Florida today, or adding air-conditioning work to an existing contracting business, cannot apply for Class C. The realistic paths into HVAC contracting now are the Class A or Class B air-conditioning license, or the Mechanical contractor license, each of which remains open to new applicants who meet the experience, education, and exam requirements described elsewhere in this brief. A contractor who inherits or buys a business that holds an active Class C license should confirm through the state's license lookup that the license is current, since a lapsed Class C license cannot be reinstated as a new Class C credential; once it goes null and void past reinstatement, the contractor has to qualify under one of the classes that is still open to new applicants.

Florida Statute 489.113 sets out who has to be certified and who can instead be registered. A person who wants to contract on a statewide basis must first pass the state certification exam and hold a certificate from the department. A person who wants to contract on less than a statewide basis, meaning inside a single local jurisdiction, can instead register after meeting that jurisdiction's own competency requirement, and the registration only authorizes work inside the jurisdiction that granted it. Either way, a person must be certified or registered to legally engage in the business of contracting in Florida; there is no path that skips both. The statute also controls how HVAC work relates to other trades on a job. A contractor must subcontract electrical, mechanical, plumbing, roofing, sheet metal, swimming pool, and air-conditioning work unless that contractor personally holds a state certificate or registration in that specific trade category. This means a general contractor building a new home cannot self-perform the HVAC installation without also holding an air-conditioning, mechanical, or equivalent license; the general license does not extend that far. A subcontractor who is not separately certified or registered may still perform HVAC work under the direct supervision of a properly licensed contractor, as long as the work stays inside the supervising contractor's licensed scope and that contractor remains responsible for it. This supervision path lets HVAC crews include helpers and apprentices who are not yet individually licensed, but it does not substitute for the supervising contractor holding the correct class of license for the work being performed.

Florida's checklist for the Certified Air Conditioning Contractor license (form CILB 5-G and 5-H) states that applicants are required to have four years of experience, or a combination of college education and experience, before applying, with the full detail spelled out on the application's own instruction pages rather than summarized in one place on the board's website. Florida Statute 489.113 adds a specific shortcut: an applicant who has earned a baccalaureate degree in building construction from an accredited four-year college, or a related degree approved by board rule, with a grade point average of 3.0 or higher, only has to take and pass the business and finance part of the exam, skipping the trade knowledge and contract administration portions that other applicants must sit for. Military experience also counts. The board's checklist directs applicants to submit a Veteran Fee Waiver and Military Service Verification Form so that time served in the military can be applied toward the experience requirement, and notes that veterans, their spouses, and Florida National Guard members may qualify for a fee waiver, fee reimbursement, or fee discount on top of that credit. Every initial applicant, regardless of experience path, must also pass a background check through fingerprints submitted to a Livescan service provider registered with the Florida Department of Law Enforcement, and must submit a personal credit report as part of demonstrating financial responsibility, a requirement covered in more depth in the insurance and financial responsibility section of this brief.
The Department of Business and Professional Regulation contracts with Professional Testing, Inc. to register candidates for, and to develop and score, the Construction Industry Licensing Board's professional exams. Anyone who wants to sit for the construction trade knowledge, contract administration, project management, or business and finance portions of the exam has to apply directly with Professional Testing, Inc. rather than through DBPR's general application system, using the Initial and Retake Examination Application, board form CILB 1. An applicant for the certification exam must be at least 18 years old. As noted earlier, a bachelor's degree in building construction from an accredited four-year program, with a 3.0 grade point average or better, allows the applicant to skip straight to the business and finance section instead of sitting for the trade knowledge exam. DBPR's own checklist is explicit that passing the exam is a separate step from becoming licensed: a passing grade alone does not grant licensure, and an applicant should confirm every other requirement is met before scheduling the exam, since the fee paid to test is not refunded just because the applicant later turns out to be ineligible on some other ground. Applicants apply either directly with the exam vendor online or by submitting a printable paper application, and the department's own guidance recommends creating a DBPR online services account and linking an Exam Candidate ID number before applying, since first-time users otherwise cannot process their results online once the exam has been completed and scored.
Florida Statute 489.109 caps what the Construction Industry Licensing Board can charge by rule. For a certificate, the initial application fee cannot exceed 150 dollars, and if an examination cost is bundled into that application fee, the combined amount cannot exceed 350 dollars. The initial certification fee and the certification renewal fee each cannot exceed 250 dollars. For a registration instead of a certificate, the initial application fee cannot exceed 100 dollars, and the initial registration fee and its renewal cannot exceed 200 dollars. Qualifying an additional business organization under either a certificate or a registration carries its own initial application fee and renewal fee, statutorily set at 50 dollars. Inactive-status renewal fees cannot exceed the equivalent active-status renewal fee and, separately, cannot exceed 50 dollars in any case. Those figures are ceilings the board may not exceed; the board sets the actual dollar amount by rule within them. DBPR's own published renewal table for Air Conditioning Contractor (Class A, B, and C) and for Mechanical Contractor lists the current renewal fee for a certificateholder or registrant as 205 dollars, plus 50 dollars for each additional qualified business the license holder is attached to. A contractor renewing both an individual license and a qualifying-agent relationship to a business should expect to pay both amounts together at each renewal cycle, and should confirm the current figure on DBPR's own site before paying, since the board can adjust the rate by rule inside the statutory ceiling described above.
Florida does not require a HVAC contractor to post a fixed-dollar surety bond as a precondition of state certification the way many other states do. Instead, Florida Statute 489.115(5) requires every applicant, as a condition of initial issuance or renewal, to submit a sworn affidavit stating that the applicant carries workers' compensation insurance as required under Chapter 440, plus public liability insurance and property damage insurance for the protection of the public, in amounts the board sets by rule; the statute itself does not print the dollar minimum, and the board's administrative rule setting that figure was not available to confirm through this brief's sources, so no specific number is stated here. Separately, Section 489.115(7) requires every initial applicant to submit a credit report from a nationally recognized credit agency reflecting financial responsibility, and lets the board's rules set guideline minimums for net worth, cash, and bonding capacity of no more than 20,000 dollars for Division I certificateholders and no more than 10,000 dollars for Division II certificateholders. Up to half of that financial-responsibility requirement can be satisfied instead by completing a board-approved 14-hour financial responsibility course, which is the path the board points applicants toward when a credit score falls below roughly 660 on a FICO-derived scale. On top of the state affidavit, DBPR's own license checklist separately confirms that an applicant must obtain workers' compensation insurance, or a valid exemption from it, within 30 days after the license is issued, and that failing to keep that coverage in force is grounds for the board to suspend, revoke, or deny renewal of the license.
Florida certificates and registrations for HVAC contractors renew on a two-year cycle rather than annually. Florida Statute 489.115(4) requires every certificateholder or registrant who wants to continue to renew every two years, and DBPR mails a renewal application ahead of each deadline. The board's own renewal table sets the actual renewal date by license status: a registered contractor renews on August 31 of odd-numbered years, and a certified contractor renews on August 31 of even-numbered years. To renew, a licensee must show at least 14 classroom hours, each at least 50 minutes long, of continuing education completed during that two-year period. Of those 14 hours, the board requires at least one hour each on workplace safety, business practices, workers' compensation, and laws and rules, with the remaining hours open to any board-approved construction-related course; a licensee who has held the license for less than a full two-year cycle is not required to complete the full 14 hours for that first renewal. DBPR's Find a CE Course tool lets a licensee search board-approved providers by subject area. A licensee who lets a license go inactive still owes continuing education to reactivate it, and a license that lapses into delinquent status long enough can become null and void, after which the only way back into that specific license class may be to reapply and test again rather than simply pay a late fee. Licensees should track their own renewal date closely, since the two-year, staggered-by-status cycle does not match a simple calendar-year renewal that many other license types use.
Florida Statute 489.115(3) lets the Construction Industry Licensing Board certify an applicant by endorsement instead of by sitting for Florida's full exam, under several alternate paths. An applicant qualifies if they have passed a national, regional, state, or United States territorial licensing exam that the board finds substantially equivalent to Florida's exam and otherwise meets Florida's certification requirements. An applicant also qualifies by holding a current, valid contracting license from another state or territory whose licensing criteria the board finds substantially equivalent to Florida's own criteria, or by holding a license from a state or territory that has entered into a specific reciprocal agreement with the board. A fourth path covers a contractor who has held a valid, current out-of-state contracting license for at least ten years before applying in Florida, provided the application is made while that license is still active or within two years after it last was. Under any of these endorsement paths, the board can still evaluate the applicant's technical competence on Florida-specific building code topics such as wind mitigation and water intrusion, and it can weigh whether the applicant's out-of-state license was ever revoked, suspended, or otherwise disciplined. Endorsement applicants in Division I trades, which includes air-conditioning and mechanical contracting, and roofing contractors, must also complete a two-hour course on the Florida Building Code that covers wind mitigation techniques, which can be completed online. Separately, Florida Statute 489.1455 lets counties and municipalities issue local journeyman licenses in the mechanical and HVAC trades to individuals who score at least 70 percent on a qualifying exam, a local-level credential distinct from state certification.

Florida Statute 489.127 makes unlicensed contracting a crime, not just a civil violation. A first violation by an unlicensed person is a misdemeanor of the first degree, punishable under Sections 775.082 or 775.083. A person who commits a second or later violation, after already having been found guilty once, faces an escalated charge, and anyone who engages in unlicensed contracting during a period covered by a declared state of emergency commits a felony of the third degree, punishable under Sections 775.082 or 775.083. Beyond the criminal exposure, Florida Statute 489.13 lets the department impose its own administrative fine of up to 10,000 dollars on any unlicensed person found guilty of unlicensed contracting, on top of recovering the department's reasonable investigative and legal costs for the case. Contracts signed by an unlicensed contractor are not just risky, they are legally unenforceable against the customer under Florida Statute 489.128, which means an unlicensed contractor who is not paid generally cannot sue to collect. A related statute, 489.126, separately criminalizes a licensed or unlicensed contractor who takes money for a job and then fails to perform or misapplies the funds, with penalties scaled to the dollar amount involved, from a first-degree misdemeanor under 1,000 dollars up to a first-degree felony at 200,000 dollars or more. Local governments also have their own enforcement tools alongside the state's, including cease and desist orders against anyone contracting without the required certification or registration, and Florida law lets a local government pursue a civil fine against a person who falsely claims to be licensed or insured in an offer, proposal, bid, or advertisement.

Florida Statute 489.119(5) requires every registered or certified contractor to affix their registration or certification number to every building permit application and to every building permit issued and recorded, and requires city and county building departments to confirm that number before issuing the permit. The same subsection requires the certification or registration number to appear in every offer of services, business proposal, bid, contract, or advertisement, in any medium, that the contractor or their business organization uses in the practice of contracting. If a vehicle carries the contractor's name, or any text or artwork that would lead a reasonable person to believe the vehicle is used for contracting, the registration or certification number must be conspicuously and legibly displayed along with that name, text, or artwork; the statute notes this does not create a separate, standalone requirement to letter a plain, unmarked work vehicle. The statute defines advertisement broadly enough to cover any medium, but carves out business stationery and small promotional novelty items such as balloons, pencils, and clothing. Enforcement is staged rather than immediate: the board issues a notice of noncompliance for a first offense, and only assesses a fine or issues a citation if the contractor fails to correct the omission within 30 days, or commits a later offense. On top of that, a local government can impose its own civil fine under Section 489.127(5) against anyone who falsely claims in an ad, bid, or proposal to be a licensed or insured contractor without actually holding the license or coverage claimed, an enforcement tool aimed squarely at unlicensed operators who advertise as if they were licensed.

DBPR runs a single public license search covering every license type it regulates, including every HVAC-related certification and registration issued by the Construction Industry Licensing Board. The board's construction industry page links directly to this tool under the heading Verify a Licensee, and the search itself lives on DBPR's licensing portal. A customer, general contractor, or property manager can search by the contractor's name, license number, or business name and see the license's current status, its class (for example Certified Class A Air Conditioning Contractor or Mechanical Contractor), its issue and expiration dates, and whether any disciplinary action is on file. Because Florida runs a two-year renewal cycle staggered by certified versus registered status, a lookup is the only reliable way to confirm a license is currently active rather than relying on a printed card or a number written on an invoice, since a license can lapse into delinquent or null and void status between renewal notices. A contractor who holds a registered rather than certified license will also show the specific jurisdiction the registration covers, which matters because a registered contractor cannot legally perform work outside that jurisdiction even if the license otherwise looks current and unrestricted. Property owners hiring HVAC work in Florida's largest metro areas should run this check before signing a contract, since a license that is active in one Florida jurisdiction is not automatically valid everywhere in the state unless it was issued as a certified, not registered, license.
Florida Statute 489.113(4) preempts local governments from making a state-certified HVAC contractor pass a second competency test to work in their jurisdiction. Once a contractor holds a current certificate, the statute requires only that the contractor show that certificate to the local building official, tax collector, or other permitting authority in Miami-Dade, Jacksonville, Tampa, Orlando, or any other Florida city or county, and pay the same occupational license and building permit fee that any other applicant would pay; the local jurisdiction cannot separately re-test the contractor's competency in the trade. A local construction regulation board does keep narrower authority to deny, suspend, or limit a specific contractor's permitting privileges, but only after a public hearing finds that contractor guilty of fraud or a willful building code violation, not as a routine licensing gate. That state-level preemption covers competency testing, not every local requirement. Florida's statute separately references Chapter 205, the state law governing local business tax receipts, and treats a Chapter 205 business tax receipt as distinct from a Chapter 489 contractor license; a contractor still generally needs a local business tax receipt to operate in each city or county where the business is based or performs work, on top of the state certification, since one does not substitute for the other. A registered, rather than certified, HVAC contractor faces a different picture in each metro: because registration is tied to the specific jurisdiction that granted it, a registered contractor in Miami-Dade County has no automatic right to perform the same work in Jacksonville or Orange County without registering there separately, unlike a certified contractor who already covers the whole state.

Holding a Florida HVAC or mechanical contractor license does not by itself satisfy a separate federal requirement that applies to the technicians actually handling refrigerant. The U.S. Environmental Protection Agency's Section 608 program, under 40 CFR Part 82, Subpart F of the Clean Air Act, requires that any technician who maintains, services, repairs, or disposes of equipment that could release ozone-depleting refrigerants, or their common substitutes such as hydrofluorocarbons, into the atmosphere must hold EPA Section 608 technician certification, and it prohibits intentionally venting those refrigerants during that work. This is a federal, individual-technician requirement layered on top of, not replacing, Florida's state contractor license; a business can hold a valid Class A, Class B, or Mechanical contractor license while an uncertified technician on its crew is still violating federal law by servicing a covered system. EPA itself does not issue the certification card. Certification is obtained by passing an exam through an EPA-approved certifying organization, covering a Core section plus one or more specialty sections: Type I for small appliances, Type II for high-pressure systems, and Type III for low-pressure systems; a technician who passes all three specialty sections alongside the Core exam is commonly described as holding Universal certification. Because almost all central, residential, and light commercial air-conditioning and heat pump work in Florida involves equipment covered by Type II, and because refrigeration work often adds Type I or Type III depending on the equipment, an HVAC contracting business operating in Florida should treat Section 608 certification as a standard requirement for every technician who opens a sealed refrigerant system, independent of what license class the business itself holds under Chapter 489.
These are common details other guides publish about Florida, but we could not verify them from the agency source. Confirm them directly before relying on them.
Yes. The Construction Industry Licensing Board, inside the Department of Business and Professional Regulation, issues certified or registered licenses for HVAC, central air conditioning, heating, ventilating, and refrigeration work under Chapter 489 of the Florida Statutes, and a person must hold one of these licenses to legally contract for that work.
Class A air-conditioning contractors have unlimited scope for central air conditioning, refrigeration, heating, and ventilating work. Class B is the same scope capped at 25 tons of cooling and 500,000 BTU of heating per system. Mechanical contractors (CM or RM) carry the same unlimited scope as Class A under a different license name.
No. Class C is closed to new applicants. Florida only recognizes Class C for contractors whose certification or registration in that class was already valid on October 1, 1988, and no one else may be registered or certified in that class.
DBPR's checklist for the certified air conditioning contractor license lists four years of experience, or a combination of college education and experience, as the baseline, with full detail on the application's own instructions and a shortcut to one exam section for a qualifying construction degree.
The Department of Business and Professional Regulation contracts with Professional Testing, Inc. to register candidates for, and to develop and score, the trade knowledge, contract administration, project management, and business and finance exam sections.
DBPR's published renewal table lists 205 dollars for Air Conditioning Contractor (Class A, B, and C) and for Mechanical Contractor, plus 50 dollars for each additional qualified business, due every two years on a date set by whether the license is registered or certified.
Not a fixed bond amount by statute. Florida requires an affidavit of workers' compensation, public liability, and property damage insurance in amounts set by board rule, plus a credit report showing financial responsibility, with a bonding and net worth guideline capped at 20,000 dollars for Division I license holders.
Certificates and registrations renew every two years. A licensee must complete at least 14 classroom hours of continuing education each cycle, including hours on workplace safety, business practices, workers' compensation, and laws and rules.
Often, yes, through endorsement. Florida certifies applicants who passed a substantially equivalent exam elsewhere, who hold a license from a state with a reciprocal agreement, or who have held a valid out-of-state license for at least ten years, subject to a Florida building code course.
A first offense is a first-degree misdemeanor, escalating to a third-degree felony for a repeat offense or unlicensed work during a declared state of emergency. DBPR can also impose an administrative fine of up to 10,000 dollars, and any contract signed is legally unenforceable by the unlicensed contractor.
Yes. Florida Statute 489.119(5) requires the certification or registration number on every permit, offer of services, bid, contract, and advertisement, and on any vehicle that would lead a reasonable person to believe it is used for contracting.
No. EPA Section 608 technician certification is a separate federal requirement under the Clean Air Act for anyone who services equipment holding covered refrigerants, obtained through an EPA-approved certifying organization, and it applies on top of, not instead of, the state contractor license.
