Florida HVAC License Requirements: How to Verify a Contractor Before You Hire

Who Regulates HVAC Contractors in Florida?

Florida Department of Business and Professional Regulation (DBPR)
Construction Industry Licensing Board (CILB)

• License lookup: myfloridalicense.com
• Phone: (850) 487-1395
• Board website: floridasconstructionindustry.com

The CILB is the state-level authority for Certified HVAC contractors. Registered contractors are additionally licensed at the county or municipal level but must meet state-defined standards to qualify.

Florida HVAC License Types

For residential homeowners, two license types matter most:

A Class A or Class B Air-Conditioning Contractor license covers 100% of residential HVAC work — new installations, replacements, ductwork, mini-splits, and system maintenance. Class B is sufficient for any single-family home because residential systems never reach 25 tons.

The Most Important Distinction: Certified vs. Registered

This is what makes Florida different from most states — and what trips up homeowners more than anything else.

How to Verify a Florida HVAC Contractor License in 60 Seconds

Go to: myfloridalicense.com

1. Click "License Verification" in the top navigation
2. Under "License Type," select "Contractor"
3. Search by Business Name, License Number, or the contractor's name
4. Review the result for:
   • License Status: Must say "Active" — "Null and Void," "Delinquent," or "Suspended" all mean stop
   • License Type: Should be CAC (Class A or B), CMC, or appropriate type
   • Expiration Date: Florida HVAC licenses renew every two years; expiration is August 31 of odd-numbered years
   • Certified or Registered: For Registered, verify the county matches yours

The Qualifying Agent Requirement (Florida-Specific)

Florida has a licensing structure most homeowners aren't aware of: the Qualifying Agent. Under Florida law, a contractor's license is issued to an individual — not to a business entity. When a licensed contractor works through a company (LLC, corporation, DBA), they must be listed as the Qualifying Agent of that business with DBPR.

What this means when you hire:

• The company doing your work should have a named Qualifying Agent on file with DBPR
• The Qualifying Agent is the person responsible — legally and professionally — for all work performed under that license
• You can verify the Qualifying Agent name in the myfloridalicense.com record

Red flag: A company that cannot name its Qualifying Agent, or whose named QA doesn't match the DBPR record, is worth investigating before any work begins.

Tampa and Hillsborough County Permit Requirements

Permits are a separate requirement from licensing — and in the Tampa metro area, both apply to nearly all HVAC work.

City of Tampa: Homes within Tampa city limits fall under the City of Tampa Building & Development Services department rather than Hillsborough County. The permit requirements are functionally the same, but permits must be obtained from the City. Confirm with your contractor which department handles your address.

Who pulls the permit: A licensed contractor should always pull the permit in their name. If a contractor asks you to pull the permit yourself, that is a significant red flag. See our HVAC Permits guide for the full explanation.

Permit cost estimate: Mechanical permits in the Tampa metro area typically run $75–$200 for a standard residential HVAC replacement. Permit cost should be included in your contractor's estimate — not billed separately after the fact.

What Happens If Work Is Done Without a License or Permit in Florida

For the contractor: Under Florida Statute §489.127, working as an unlicensed contractor is a first-degree misdemeanor on the first offense and a third-degree felony on subsequent offenses. DBPR can issue cease-and-desist orders and fines of up to $5,000 per violation.

For the homeowner:

• Insurance claims may be denied. Most homeowner's insurance policies exclude coverage for work done without required permits.
• Failed home sale. Florida real estate transactions require disclosure of unpermitted work. Unpermitted HVAC work discovered during inspection can kill a sale or require expensive remediation.
• Code compliance orders. The local building department can order you to remove and redo it — at your expense — even years later.
• Voided equipment warranty. Most manufacturers explicitly require licensed installation and permit-verified inspections to maintain parts and compressor warranties.

6 Questions to Ask Before Hiring a Florida HVAC Contractor

1. "What is your Florida license number, and are you Certified or Registered?" Write it down, then verify at myfloridalicense.com before the appointment ends.
2. "Are you the Qualifying Agent, or who is the QA on record with DBPR?" Legitimate contractors know the answer instantly.
3. "Will you pull the mechanical permit for this job?" The correct answer is yes, always.
4. "Does your quote include permit fees?" If not, ask for a separate line item.
5. "Do you carry general liability and workers' compensation insurance? Can I see the certificates?" Request current COIs with your name listed as certificate holder.
6. "Who performs the EPA Section 608 certified refrigerant work?" Any technician handling refrigerant must hold EPA Section 608 certification.
