Florida: HVAC contractor licensing, reciprocity and contract rules.

This page lists what Florida publishes about licensing an HVAC or mechanical contractor and contracting with homeowners: who issues the licence, whether one is required statewide, the classes and qualifications, insurance or bond minimums, reciprocity with other states, renewal and continuing education, and the state's home-improvement contract statute if it has one.

It is built for owners of residential HVAC companies, especially those hiring across a state line or opening a second territory. Every entry is a snapshot of what the cited source published on the verification date; it is a research starting point, not legal advice.

Florida, field by field.

Contractor licensing authority

Florida Department of Business and Professional Regulation (DBPR), Construction Industry Licensing Board (CILB). The DBPR page states: "The Construction Industry Licensing Board is responsible for licensing and regulating the construction industry", and that it reviews disciplinary cases and holds informal licensure and discipline hearings.

HVAC licence required

Statewide. Fla. Stat. § 489.127(1)(f) prohibits a person from engaging "in the business or act in the capacity of a contractor" or advertising as available to do so "without being duly registered or certified" (§ 489.127(2): a first-degree misdemeanor, and a third-degree felony for a repeat violation or a violation during a declared state of emergency). § 489.105 (2026 Florida Statutes) defines the Class A air-conditioning contractor (services "unlimited in the execution of contracts" for central air-conditioning, refrigeration, heating and ventilating systems), the Class B air-conditioning contractor (services "limited to 25 tons of cooling and 500,000 Btu of heating in any one system"), the Class C air-conditioning contractor (business "limited to the servicing of" air-conditioning, heating or refrigeration systems; only a person registered or certified as Class C as of October 1, 1988 may continue in that class) and the mechanical contractor (unlimited, including boilers and pressure vessels); a certified contractor (occupation code beginning "C") is "allowed to contract in any jurisdiction in the state without being required to fulfill the competency requirements" of that jurisdiction, while registered contractors (code "R") "may contract only in such jurisdictions" for which they are registered. The § 489.105(3) definition of "contractor" contains no dollar threshold.

Licence classes & qualifications

Certified Air Conditioning Contractor Class A (CILB 5-G) and Class B (CILB 5-H) as an individual (DBPR checklist title), with registered equivalents. Fla. Stat. § 489.111(2): a person is eligible for licensure by examination if the person "Is 18 years of age", "Is of good moral character" and meets one of: a baccalaureate degree from an accredited 4-year college in engineering, architecture or building construction plus "1 year of proven experience" ((2)(c)1.); "a total of at least 4 years of active experience" as a skilled worker or foreman, "provided, however, that at least 1 year of active experience shall be as a foreman" ((2)(c)2.); or combinations of college credit and experience ((2)(c)3.). § 489.111(2)(c)5. lets a certified Class C holder become Class B with 3 years' or Class A with 4 years' proven experience, and a Class B holder become Class A with 1 year, on passing the higher examination. The DBPR checklist (CILB 5-G/5-H) states: "Applicants are required to have four years of experience or a combination of college and experience"; certified applicants "must first take and pass a state certification examination"; applicants submit Livescan fingerprints and a personal credit report that "must include a FICO derived credit score"; applicants must be at least 18. The CILB Financial Responsibility and Stability Requirements document requires no unsatisfied liens or judgments and "a 660 FICO derived credit score or higher", or completion of a board-approved 14-hour Financial Responsibility Course.

Insurance / bond minimum

Fla. Stat. § 489.115(5)(a): the applicant submits an affidavit attesting to workers' compensation coverage under chapter 440 and to "public liability insurance, and property damage insurance for the safety and welfare of the public" "in amounts determined by rule of the board". Fla. Admin. Code R. 61G4-15.003 (Public Liability Insurance; last amended 11/15/2007) sets the amounts: for an Air Conditioning Contractor, $100,000 public liability and $25,000 property damage; for a Mechanical Contractor, $100,000 public liability and $25,000 property damage (table in subsection (2)(h), captioned "Proper aggregate amount of public liability and property damage"); subsection (1) requires the signed affidavit as a prerequisite to initial issuance, renewal or a status change and makes failure to maintain the coverage a violation; subsection (2) provides for random audits in which the licensee produces a certificate of insurance naming the Board as certificate holder with a 30-day cancellation notice. The DBPR checklist states that applicants attest to insurance "in the amounts determined by Board rule" and "are also required to obtain workers compensation insurance or obtain an exemption from workers compensation insurance within 30 days of issuance of their license". No surety-bond requirement appears in § 489.115 or in Rule 61G4-15.003.

Reciprocity

The CILB Reciprocity list (file metadata: last modified Oct 16, 2024) states that the CILB "currently has reciprocal licensing agreements with" Louisiana, North Carolina and Mississippi for "General, Building, and Residential licenses" only. The CILB Endorsement list of "states with exams previously found to be substantially similar to Florida's exam" includes Arkansas Master HVACR Contractor, California Class A Air Conditioning Contractor, Iowa Master HVACR Contractor and South Carolina Mechanical - Air Conditioning Contractor. Fla. Stat. § 489.115(3)(a) allows certification by endorsement for an applicant who has passed a national, regional, state or territorial licensing examination "substantially equivalent to the examination required by this part" and meets the § 489.111 requirements, and § 489.115(3)(d) allows endorsement for an applicant who has held a valid contracting licence from another state or territory "for at least 10 years before the date of application".

Renewal & continuing education

Fla. Stat. § 489.115(4)(a): the holder "shall renew the certificate or registration every 2 years"; § 489.115(4)(b)1.: "at least 14 classroom hours of at least 50 minutes each of continuing education courses during each biennium", covering workers' compensation, business practices and workplace safety, "1 hour of which must deal with laws and rules", plus wind mitigation methodologies "for applicable licensure categories". Fla. Admin. Code R. 61G4-18.001 (effective 6/26/2023) implements this: 14 hours per renewal cycle, including one hour each in a specialized or advanced module course, workplace safety, business practices, workers' compensation, and laws and rules; the wind-mitigation hour applies only to the General, Building, Residential, Roofing, Specialty Structure and Glass and Glazing categories, not to air-conditioning or mechanical contractors; no continuing education is required for the year in which a licence is first issued, and a licensee issued more than 12 months before the end of a biennium completes seven hours for the first renewal; up to four hours may be earned by attending a Board disciplinary session.

Home-improvement contract rule

Fla. Stat. § 489.126(2)(a): a contractor who receives an initial payment "totaling more than 10 percent of the contract price" for residential real property work must "Apply for permits necessary to do work within 30 days after the date payment is made" and "Start the work within 90 days after the date all necessary permits for work, if any, are issued", absent just cause or a written agreement for a longer period; § 489.126(5) grades violations from a first-degree misdemeanor (total money received less than $1,000) through third- and second-degree felonies to a first-degree felony ($200,000 or more), and § 489.126(4)(b) permits intent to be inferred where the contractor "fails to refund any portion of the money owed within 30 days after receiving a written demand". § 489.1425(1): a contract for repair, restoration, improvement or construction to residential real property must contain the Florida Homeowners' Construction Recovery Fund notice beginning "PAYMENT, UP TO A LIMITED AMOUNT, MAY BE AVAILABLE FROM THE FLORIDA HOMEOWNERS' CONSTRUCTION RECOVERY FUND", "except where the value of all labor and materials does not exceed $2,500" (§ 489.1425(2): fine up to $500 for a first violation, $1,000 per subsequent violation). § 713.015(1): "Any direct contract greater than $2,500 between an owner and a contractor" for improvements to residential property of up to four units must contain the Construction Lien Law notice beginning "ACCORDING TO FLORIDA'S CONSTRUCTION LIEN LAW (SECTIONS 713.001-713.37, FLORIDA STATUTES)". Home solicitation sales: § 501.021(1) covers consumer goods or services "with a purchase price in excess of $25" solicited away from the seller's fixed location and excludes a sale "that results from a request for specific goods or services by the purchaser"; § 501.025 allows cancellation "until midnight of the third business day after the day on which the buyer signs an agreement or offer to purchase" (three business days, the same window as the federal rule). Financed sales: Fla. Stat. ch. 520, Part V. § 520.61(13) defines a "home improvement contract" as a written agreement between a home improvement finance seller and an owner for a home improvement "when all or part of the contract price is to be paid in installments over a period of time greater than 90 days"; § 520.61(14) defines a home improvement finance seller as a person who enters into two or more such contracts of $500 or more in a calendar year; § 520.63(1): "A person may not engage in or transact any business as a home improvement finance seller" without a licence from the office (banks, savings associations, credit unions and chapter 494 part III licensees excepted); § 520.73: "Every home improvement contract shall be evidenced by a written agreement and shall be signed by the parties", completed in full without blank spaces, stating the seller's name, address and licence number, the approximate start and completion dates, a description of the work and materials, the financing figures, whether the seller carries workers' compensation and public liability insurance, and a 10-point boldface "Notice To Owner" above the owner's signature ("Do not sign this home improvement contract in blank"; "You are entitled to a copy of the contract at the time you sign"). Outside chapter 520 Part V, no deposit cap and no separate home-improvement contractor registration appear on the pages read.
