§489.105(3)(f) Class A Air-Conditioning Contractor
“Class A air-conditioning contractor” means a contractor whose services are unlimited in the execution of contracts requiring the experience, knowledge, and skill to install, maintain, repair, fabricate, alter, extend, or design, if not prohibited by law, central air-conditioning, refrigeration, heating, and ventilating systems, including duct work in connection with a complete system if such duct work is performed by the contractor as necessary to complete an air-distribution system, boiler and unfired pressure vessel systems, and all appurtenances, apparatus, or equipment used in connection therewith, and any duct cleaning and equipment sanitizing that requires at least a partial disassembling of the system; to install, maintain, repair, fabricate, alter, extend, or design, if not prohibited by law, piping, insulation of pipes, vessels and ducts, pressure and process piping, and pneumatic control piping; to replace, disconnect, or reconnect power wiring on the line or load side of the dedicated existing electrical disconnect switch on single phase electrical systems; to repair or replace power wiring, disconnects, breakers, or fuses for dedicated HVAC circuits with proper use of a circuit breaker lock; to install, disconnect, and reconnect low voltage heating, ventilating, and air-conditioning control wiring; and to install a condensate drain from an air-conditioning unit to an existing safe waste or other approved disposal other than a direct connection to a sanitary system. The scope of work for such contractor also includes any excavation work incidental thereto, but does not include any work such as liquefied petroleum or natural gas fuel lines within buildings, except for disconnecting or reconnecting changeouts of liquefied petroleum or natural gas appliances within buildings; potable water lines or connections thereto; sanitary sewer lines; swimming pool piping and filters; or electrical power wiring. A Class A air-conditioning contractor may test and evaluate central air-conditioning, refrigeration, heating, and ventilating systems, including duct work; however, a mandatory licensing requirement is not established for the performance of these specific services.

02 Scope assertions
No scope assertion row is seeded for this category yet — we do not invent scope statements without verbatim evidence.
03 The subcontract rule
A contractor shall subcontract all electrical, mechanical, plumbing, roofing, sheet metal, swimming pool, and air-conditioning work, unless such contractor holds a state certificate or registration in the respective trade category (F.S. §489.113(3)). Exceptions include: a general, building, or residential contractor need not subcontract the installation, or repair made under warranty, of wood shingles, wood shakes, or asphalt or fiberglass shingle roofing materials on a new building of his or her own construction (§489.113(3)(b)); a general contractor need not subcontract structural swimming pool work (§489.113(3)(c)).

04 Certified or registered
A certified contractor holding this category may contract in any Florida jurisdiction without meeting that locality's competency requirements (F.S. §489.105(8)); a registered contractor holding it may contract only where local licensing was met, and only for the registered type of work (§489.105(10), §489.117(1)(b)). The statute defines the category — it does not make it certified-only. Differences explained on the certified vs registered page. S-FL-105 S-FL-117
05 Local permit layer
Holding this category does not decide permits: the permit issuer must ascertain that the applicant is certified or registered in that area before issuing (F.S. §489.131(5)), and permit systems and fees remain county/municipal powers (§489.131(3)(a), (d)).
