12.1 Chapter 489: Certified vs Registered & Qualifying Agents

12.1 Chapter 489: Certified vs Registered & Qualifying Agents

Business & Finance Area F — Complying with Government Regulations — is 15% of 120 questions, roughly 18 items. Florida Statutes Chapter 489 (Contracting) and Chapter 455 (professional regulation overlay) sit at the center of that cluster, carried on the 2026 B&F list by the 2025 bound Chapter 455 PDF and the Contractors Manual 2025 (used beginning February 1, 2026). Candidates who treat “HVAC license” as one blob miss the exam. Chapter 489 splits who may contract (certified versus registered), what they may install (Class A versus Class B versus Class C), and who is on the hook when the company bids (primary qualifying agent, secondary qualifying agent, financially responsible officer).

Certified statewide versus registered local

F.S. 489.105(8) defines a certified contractor as any contractor who possesses a certificate of competency issued by the Department of Business and Professional Regulation (DBPR) and who shall be allowed to contract in any jurisdiction in the state without being required to fulfill the competency requirements of that jurisdiction. F.S. 489.105(10) defines a registered contractor as any contractor who has registered with the department after fulfilling the competency requirements in the jurisdiction for which the registration is issued. Registered contractors may contract only in such jurisdictions.

That pair is the highest-yield Chapter 489 distinction on the HVAC B&F exam. Certification is the statewide ticket you earn by passing the CILB examination, meeting experience and financial-responsibility rules, and holding the certificate. Registration is the state recording of a local competency license. A Hillsborough County registered Class B contractor who drives to Orange County and pulls a permit on a 5-ton changeout is contracting outside the registration. A certified Class B contractor with the same skill may exhibit the current certificate to the Orlando building official, pay the local occupational license and permit fees, and work — F.S. 489.113(4)(a) says the certificateholder is required only to exhibit the current certificate and pay those local fees. The certificate itself is not transferable (489.113(5)). Selling the LLC does not sell the license.

Local governments still issue permits, collect occupational-license taxes, and can deny or condition a certified contractor’s permitting authority after a public hearing for fraud or a willful building-code violation (489.113(4)(b)). They can also withhold permits if the contractor fails to show the public-liability, property-damage, and workers’ compensation coverages required by 489.115(5) and 489.114 (489.113(4)(c)). Local control of competency testing is what certification displaces. Do not tell the exam that a certified HVAC contractor is free of local permits.

F.S. 489.113(1) states the exam path in one sentence: a person who wants to contract statewide must be certified; a person who wants to contract on other than a statewide basis must be registered, unless an exemption applies. F.S. 489.113(2) then makes the licensing duty absolute: a person must be certified or registered to engage in the business of contracting in this state. An unlicensed helper may perform construction work under a certified or registered supervisor if the work is within that supervisor’s scope, the supervisor is responsible, and the helper is not independently engaged in a trade that itself requires a contractor license under 489.105(3)(d)–(o). That supervised-helper rule does not let an unlicensed person bid HVAC jobs.

Class A unlimited versus Class B 25 tons / 500,000 Btu

F.S. 489.105(3) splits contractors into Division I (general, building, residential) and Division II (including air-conditioning). HVAC candidates are Division II. Three air-conditioning classes exist.

A Class A air-conditioning contractor (489.105(3)(f)) has unlimited capacity. The Class A contractor may install, maintain, repair, fabricate, alter, extend, or design (if not prohibited by law) central air-conditioning, refrigeration, heating, and ventilating systems, including ductwork necessary to complete an air-distribution system; boiler and unfired pressure vessel systems; piping, insulation of pipes, vessels and ducts, pressure and process piping, and pneumatic control piping; limited electrical work on single-phase dedicated existing disconnects (replace, disconnect, or reconnect power wiring on the line or load side), plus repair or replacement of power wiring, disconnects, breakers, or fuses for dedicated HVAC circuits with a circuit-breaker lock; low-voltage HVAC control wiring; and a condensate drain to an existing safe waste — not a direct sanitary connection. Class A may not run LP or natural gas fuel lines within buildings except disconnecting or reconnecting changeouts of LP or natural gas appliances, and may not do potable water, sanitary sewer, pool piping, or electrical power wiring beyond those HVAC exceptions.

A Class B air-conditioning contractor (489.105(3)(g)) has the same trade skills limited to 25 tons of cooling and 500,000 Btu of heating in any one system. Class B statutory scope includes piping and insulation of pipes, vessels, and ducts, the same single-phase electrical and low-voltage exceptions, and the same condensate-drain rule. It does not include boilers, unfired pressure vessels, or pneumatic control piping. The official Class B trade outline also drops installing systems of 25–100 tons, over 100 tons, and centrifugal compressor systems that appear on Class A. Class B candidates still need the theory of large systems for B&F and for knowing when to walk away or to hire a Class A; they may not contract those installs.

A Class C air-conditioning contractor (489.105(3)(h)) is service-only and grandfathered. Only a person who was registered or certified as Class C on October 1, 1988 remains Class C. This study guide is for A/B candidates. Do not tell the exam that Class C is a current entry path.

Worked example: a 40-ton rooftop package on a Fort Myers strip center is Class A work. A Class B qualifier who bids it has contracted outside statutory scope. A 5-ton split with 80,000 Btu of heat in a Cape Coral house is inside Class B. A hydronic boiler and pneumatic control piping on a school renovation are Class A (or mechanical), not Class B.

Primary qualifying agent, secondary qualifying agent, and FRO

The license is a person. F.S. 489.105(4) defines a primary qualifying agent as a person who possesses the requisite skill, knowledge, and experience, and has the responsibility, to supervise, direct, manage, and control the contracting activities of the business organization; who has the responsibility to supervise, direct, manage, and control construction activities on a job for which he or she has obtained the building permit; and whose qualifications have been determined by investigation and examination. F.S. 489.105(5) defines a secondary qualifying agent as a person with the same technical qualifications who has the responsibility to supervise, direct, manage, and control construction activities on a job for which he or she has obtained a permit — notice that the secondary definition does not assign company-wide contracting control or finances. F.S. 489.105(14) defines a financially responsible officer (FRO) as a person other than the primary qualifying agent who, with board approval, assumes personal responsibility for all financial aspects of the business organization.

F.S. 489.1195(1)(a) then loads the duty: all primary qualifying agents for a business organization are jointly and equally responsible for supervision of all operations of the business organization; for all field work at all sites; and for financial matters, both for the organization in general and for each specific job. If the board approves an FRO, the FRO is responsible for all financial aspects and may not be designated as the primary qualifying agent (489.1195(1)(b)). With an FRO in place, the primary qualifying agent remains responsible for all construction activities of the organization, both in general and for each specific job (489.1195(1)(c)). Secondary qualifying agents, designated by a board-approved joint agreement, are responsible only for field work at sites where their license pulled the permit and for other work they accept; they are not responsible for supervision of financial matters (489.1195(2)(e)).

F.S. 489.119 is the application statute. Contracting in your own name or as a sole proprietorship under a fictitious name: certification or registration issues only to that individual (489.119(1)). Contracting through a partnership, corporation, LLC, business trust, or any name other than that legal name: you apply as the qualifying agent of the business organization (489.119(2)). The application must include an affidavit that the applicant has final approval authority for all construction work and all business matters — contracts, specifications, checks, drafts, or payments — except where an FRO is approved. A joint venture, including a joint venture of already-qualified companies, is itself a separate organization that must be qualified (489.119(2)(e)).

The 60-day rule when the only qualifier leaves

If any qualifying agent ceases to be affiliated, that agent shall inform the department. If that agent is the only certified or registered contractor affiliated with the business organization, the organization shall notify the department and shall have 60 days from the termination to employ another qualifying agent (F.S. 489.119(3)(a)). The organization may not engage in contracting until a qualifying agent is employed, unless the executive director or chair of the board has granted a temporary nonrenewable certificate or registration to the FRO, the president, a partner, or, in a limited partnership, the general partner, who assumes all responsibilities of a primary qualifying agent. That temporary ticket only allows the organization to proceed with incomplete contracts — contracts already awarded or entered into, or jobs on which the firm was the low bidder and the contract is subsequently awarded, whether or not work has started. It is not authority to bid new work. Operating after 60 days without a designated primary qualifier is itself a prohibited act under F.S. 489.127(1)(g).

Florida HVAC scenario

Elena holds a certified Class A license and qualifies Gulf Breeze Mechanical, LLC as primary qualifying agent. Her brother Tomas holds a registered Class B license for Escambia County only. Elena may set an 80-ton chiller in Pensacola or Jacksonville. Tomas may service a 4-ton split in Pensacola under his registration; if he bids the same split in Tallahassee, he is outside 489.105(10). If Elena resigns to qualify a competitor, the LLC notifies DBPR and has 60 days to employ another qualifier. During the gap the LLC may not take a new hospital bid unless a temporary nonrenewable certificate is granted, and even then only incomplete contracts. Ownership of the LLC by Elena’s spouse does not keep the company licensed. The certificate never belonged to the LLC.
