1. Florida Department of Business and Professional Regulation — Certified A/C Contractor License

   Florida requires HVAC contractors to hold a Certified (statewide) or Registered (local) Air Conditioning Contractor license — Class A, B, or C — from the Florida DBPR Construction Industry Licensing Board (s. 489.105(3), F.S.). Applicants must pass the state examination, demonstrate qualifying experience (e.g., 4 years including at least 1 year as a foreman, or degree/experience combinations — s. 489.111, F.S.), attest to public liability and property damage insurance of $100,000/$25,000 (Rule 61G4-15.003, F.A.C.), meet financial responsibility requirements (credit report; FICO 660+ or an approved 14-hour financial responsibility course), and carry workers' compensation coverage or an exemption.

2. Florida Workers' Compensation — coverage or construction-industry exemption

   Florida classifies HVAC contracting as construction industry (Rule 69L-6.021, F.A.C.), where workers' compensation coverage is required with one or more employees (s. 440.02(20)(b), F.S.) — and a corporate officer or an LLC member owning at least 10% who performs the work counts as an employee (s. 440.02(11), (18)(b)). An owner-only LLC or corporation must therefore either carry a workers' compensation policy or file a construction-industry Certificate of Election to be Exempt with the Division of Workers' Compensation before starting paid work ($50, valid 2 years, max 3 officers/members per business, at least 10% ownership; s. 440.05). A sole proprietor or partner engaged in the construction industry is also counted as an employee (s. 440.02(18)(c)) and the s. 440.05 exemption is limited to corporate officers and LLC members — verify the coverage route with the Division, (850) 413-1609, if the business is not incorporated. Operating without required coverage risks a stop-work order and a penalty of 2x the evaded premium, $1,000 minimum (s. 440.107). Employees hired later need actual coverage from day one; an exemption covers only the named officer/member.
