HVAC Repair — Florida license requirements
01 The project
The starting point is the work itself — HVAC Repair in Florida. The job determines which trades are involved, and the trades determine which license classifications may be required.
| Component | Trade |
|---|---|
| Existing air-conditioning system | HVAC |
02 Jurisdiction
This project is evaluated for Florida — a state credential (certificate or registration) issued by DBPR through the Construction Industry Licensing Board under F.S. Chapter 489 Part I, plus the LOCAL layers: registered contractors are bound to the jurisdictions where they met local licensing (§489.105(10)), and building permits are issued locally (§489.131(3)(a)). Florida jurisdiction page.
County and city licensing, registration processes and permit fees were not verified for any Florida locality — LOCAL_AUTHORITY_REQUIRED. State requirements are not the complete story for any locality.
03 Trade → license
Relations below are recorded per state — only this jurisdiction's classifications are shown.
Trades involved: HVAC.
- May require (g) — Class B Air-Conditioning Contractor confirmed S-FL-105F.S. §489.105(3)(g): Class B is limited to 25 tons of cooling and 500,000 Btu of heating in any one system — the common repair case. The §489.103(14) exemption applies ONLY to units ≤3 tons/36,000 Btu with no ducts and a factory-installed cord and plug (REQ-FL-AC-SMALL-001).
- Alternative path (f) — Class A Air-Conditioning Contractor confirmed S-FL-105F.S. §489.105(3)(f): Class A is unlimited in scope — the required path when a system exceeds 25 tons of cooling or 500,000 Btu of heating in any one system.
- Alternative path (i) — Mechanical Contractor confirmed S-FL-105F.S. §489.105(3)(i): the mechanical contractor's scope expressly includes install/maintain/repair of central air-conditioning, refrigeration, heating and ventilating systems — an alternative credential path for HVAC repair (with a broader piping scope than the AC classes).

07 Local permit layer
The permit issuer must ascertain that the applicant is certified or registered in that area before issuing the permit (F.S. §489.131(5)); permit systems and their fees remain local (§489.131(3)(a), (d)). S-FL-131
Unenforceability guard: a contract entered by an unlicensed contractor is unenforceable and carries no lien or bond claim (F.S. §489.128) — verify status on the official lookup before relying on any outcome here. S-FL-128
