How to Get an HVAC Contractor License in Florida (2026 Guide)

In Florida, HVAC contracting is regulated by the Construction Industry Licensing Board (CILB), a division of the Department of Business and Professional Regulation (DBPR). To work as an air-conditioning contractor statewide, you need a state Certified license — earned through a combination of documented experience, financial-responsibility review, and a two-part state exam. This guide walks every step, both license classes, and the recent law changes you need to know.

⚠ This page is an unverified working draft. Every figure and rule below was assembled from research and must be confirmed against the official CILB/DBPR sources before it is relied upon. Items marked ⚠ VERIFY flag known gaps or conflicting data.

Is an HVAC license required in Florida?

Yes. Florida law requires a state-certified or (historically) locally-registered license to perform air-conditioning, heating, refrigeration, and ventilation contracting. Performing this work unlicensed is a criminal offense that can carry fines and cease-and-desist action. A Certified license issued by the CILB lets you contract anywhere in Florida.

Florida HVAC license tiers and scope of work

Florida issues two statewide certified air-conditioning classes, distinguished by the size of system you may work on:

• Certified Class A Air-Conditioning Contractor — unlimited. May install, maintain, repair, and alter air-conditioning, refrigeration, heating, and ventilation systems of any capacity, including ductwork.
• Certified Class B Air-Conditioning Contractor — limited to systems up to 25 tons of cooling and 500,000 BTU of heating. ⚠ VERIFY the exact tonnage/BTU ceiling and any duct or component restrictions against the CILB rule.

Expanded electrical scope (HB 481, effective July 1, 2024): Class A and Class B contractors may now perform additional electrical work incidental to an HVAC system — including replacing, disconnecting, or reconnecting power wiring on the line or load side of the dedicated disconnect on single-phase systems. HB 431 (effective July 1, 2026) further clarifies and expands this scope. ⚠ VERIFY the precise statutory scope language.

The future of local "Registered" contractors (SB 1142): Effective July 1, 2025, the local specialty-licensing extension ends. Local governments may only license specialty types that correspond to a state category, which may require many locally-registered HVAC contractors to upgrade to a state-certified credential. ⚠ VERIFY transition timeline and grandfathering.

Florida HVAC license requirements: are you eligible?

General eligibility

• Be at least 18 years old.
• Have a valid Social Security Number or ITIN.
• ⚠ VERIFY whether English proficiency is a formal application requirement.

Experience and education (Class A)

You must document four years of combined experience and education. Common paths:

• Four years' active experience in the trade, at least one year in a supervisory role (documented on form DBPR CILB 010).
• Bachelor's degree in a related field (engineering, architecture, building construction) plus one year of trade experience.
• Education substitutes — up to three of the four years may be satisfied by accredited college or vocational/technical credits. ⚠ VERIFY specific substitution ratios, and any credit for military service.

Experience and education (Class B)

• Four years' active experience, with one year supervisory; or
• ⚠ VERIFY whether an Associate of Arts/Science degree + one year is a valid Class B path, and the education-substitution rules.

Financial responsibility and credit

Applicants submit a credit report and demonstrate financial responsibility.

• Current rule: applicants with a FICO score below 660 may be required to complete an approved financial-responsibility course.
• Anticipated 2026 change: the CILB is expected to require a minimum 660 FICO for all applicants and remove the course option. ⚠ VERIFY whether and when this rule is adopted.

Background check

All applicants undergo a background check. A criminal record is not an automatic disqualifier; all convictions must be disclosed and the CILB reviews each case for relevance to contracting.

The application process, step by step

1. Gather documents — transcripts, experience verifications, a recent credit report, and business financial statements where applicable.
2. Complete form DBPR CILB 010 (Application for Certified Air-Conditioning Contractor), fully addressing experience, financial responsibility, and background.
3. Submit the application and fees. Certified-license application fees run $149–$249 depending on where you apply in the licensing cycle. ⚠ VERIFY current fee schedule.
4. Board review and approval. DBPR staff review for completeness; the CILB approves eligibility to sit for the exams.

The Florida HVAC contractor exam

The state contractor examination has two parts — you must pass both:

1. Trade Knowledge — installation, duct systems, refrigeration principles, electrical components, codes, and safety.
2. Business and Finance — business organization, financial management, tax and labor law, and lien law.

• Exam provider: ⚠ VERIFY the current official provider (e.g., Pearson VUE or Prometric) and testing locations on the DBPR site.
• Open-book references: the CILB publishes the approved reference list; an official book bundle and a prep course are recommended.
• Exam fees: ⚠ VERIFY — conflicting data: one source indicates $295 for both exams, another ~$80 per exam. Confirm with the provider.
• 2025 EPA Section 608 update: the federal 608 certification exam was updated to cover A2L (mildly flammable) refrigerants, new leak-detection requirements, and ventilation standards, reflecting the R-410A phase-down.

Insurance and bonding

Before your license is activated, you must show proof of insurance:

• Public liability $100,000 and property damage $25,000. ⚠ VERIFY — one source indicates a $300,000 general-liability minimum.
• Workers' compensation for employees, or an official exemption from the Florida Division of Workers' Compensation.

Renewal and continuing education

• Cycle: biennial. Certified licenses renew by August 31 of even-numbered years (e.g., 2026, 2028). Biennial renewal fee $209. ⚠ VERIFY.
• Continuing education: 14 hours per cycle, including at least one hour each in workplace safety, workers' compensation, business practices, Florida laws and rules, and advanced-module building code. Only CILB-approved providers count. ⚠ VERIFY hour breakdown and approved-provider list.

Reciprocity and endorsement

• Reciprocity with Louisiana, North Carolina, and Mississippi — but the trade exam is NOT waived; applicants must still pass the Florida Business and Finance exam. ⚠ VERIFY exactly which exams reciprocity applicants must take.
• 10-year endorsement: contractors who have held an active, unrestricted license in the same classification in another state for at least 10 years may apply by endorsement (still passing the Florida Business and Finance exam). ⚠ VERIFY conditions.

Recent and upcoming changes (2024–2026)

• July 1, 2024 — HVAC warranty simplification (HB 481): manufacturers may not condition HVAC warranties on product registration.
• July 1, 2024 — expanded electrical scope (HB 481): for Class A, Class B, and mechanical contractors, incidental to HVAC replacement.
• July 1, 2025 — local specialty licensing extension ends (SB 1142): affects locally-registered contractors.
• July 1, 2025 — voluntary licensure for certain specialty trades, centralizing authority with the CILB.
• 2025 — EPA Section 608 exam updates (A2L refrigerants, leak detection, ventilation).
• July 1, 2026 — further expanded scope (HB 431) for Class A and mechanical contractors, including certain pool heaters and additional limited electrical work.
• Anticipated 2026 — minimum 660 FICO financial-responsibility rule change.

⚠ VERIFY every bill number, effective date, and the precise statutory language above against the Florida Statutes / Florida Administrative Code.
