Hiring a Licensed HVAC Contractor in Florida: How to Check and Why License Classes, DBPR Lookups and Red Flags
Every licensed HVAC contractor in Florida has a state license number you can check online in minutes. This guide explains the license classes, shows how to verify a contractor on DBPR and lays out the risks of hiring someone who is unlicensed.
Who Licenses HVAC Contractors in Florida
Air conditioning and mechanical contractors in Florida are licensed by the Construction Industry Licensing Board, which operates under the Department of Business and Professional Regulation, known as DBPR. To earn a state certification, a contractor must document trade experience, pass state examinations covering technical work and business and law, and carry required insurance.
Florida also distinguishes between certified and registered contractors. A certified contractor holds a state license valid statewide. A registered contractor is licensed to work only in the local jurisdictions where they have shown competency. Either way, the license number should appear on estimates, contracts, vehicles and advertising. Reliance Air Services holds Florida license CAC1819474; you can read more about our team on the About Reliance Air Services page.
Florida License Classes for HVAC Work
The license class determines what size and type of system a contractor can legally install.
| License | Scope | Typical prefix |
|---|---|---|
| Class A air conditioning contractor | Heating and cooling systems with no tonnage limit, residential and commercial | CAC |
| Class B air conditioning contractor | Limited to smaller systems: up to 25 tons of cooling and 500,000 BTU of heating | Check DBPR |
| Class C air conditioning contractor | A restricted, service-focused license; confirm its exact scope on DBPR | Check DBPR |
| Mechanical contractor | The broadest scope, including AC, heating, ventilation, ductwork and commercial refrigeration | CMC |
How to Verify a Contractor License on DBPR
Open the state lookup
Go to myfloridalicense.com and choose the option to verify a license.
Search by number or name
Enter the license number from the estimate, or search the person's or company's name. Try our number, CAC1819474, to see how a result looks.
Check the status
Look for a current, active status. Expired, delinquent, suspended or revoked licenses mean the holder cannot legally contract.
Match the names
Confirm the license holder or qualified business matches the company on your contract.
Review any discipline
The record shows public complaints and disciplinary actions where they exist.
Ask for insurance
Request a certificate of insurance showing current liability and, where required, workers' compensation coverage.
Unlicensed Contractor Risks
Contracting without a license is illegal in Florida, but the bigger problems land on the homeowner. An unlicensed worker generally cannot pull a permit, so the job skips inspection. That can surface later when you sell, file an insurance claim or ask a manufacturer for warranty help.
Safety is the other concern. Air conditioners run on 240-volt circuits and handle pressurized refrigerant. Bad wiring, a poorly brazed line set or a wrongly sized breaker can lead to fire risk, leaks and early compressor failure. If a worker without workers' compensation coverage is injured on your property, you may face questions about liability. Florida's homeowner recovery fund for contractor misconduct applies to licensed contractors, so victims of unlicensed work have fewer options to recover losses.
Red Flags Before You Sign
- No license number on the quote, truck or ads
- A number that does not match the company name on DBPR
- Pressure to pull the permit yourself as an owner-builder
- Cash-only pricing or a large deposit before any work
- No written, itemized estimate
- No proof of insurance on request
- A price far below every other bid without explanation
- Urgent pressure to sign today
A License Is the Starting Point
Licensing proves a contractor met the state's minimum bar. It does not tell you about workmanship, communication or pricing. After checking the license, look at reviews, ask how the company sizes systems and whether quotes are written and flat-rate. Our guide on how to choose an HVAC contractor covers those questions, and the article on HVAC installation permits in Florida explains what a licensed installer must do on a replacement.

Common Questions
Questions Readers Ask
What license does an HVAC contractor need in Florida?
To contract for air conditioning work, a business needs a state air conditioning contractor license (Class A, B or C) or a mechanical contractor license, issued through the DBPR's Construction Industry Licensing Board, or a local registration where the work takes place. Class A carries no tonnage limit, Class B is restricted to smaller systems, and Class C focuses on servicing. Mechanical licenses cover the broadest scope.
What does CAC mean on a Florida license?
CAC is the prefix used for certified air conditioning contractor licenses issued by the state. The letters are followed by a number, such as CAC1819474 for Reliance Air Services. A certified license allows the holder to contract anywhere in Florida within the scope of their class. You can confirm any CAC number and its status on myfloridalicense.com.
How do I check if an HVAC contractor is licensed in Florida?
Visit myfloridalicense.com, choose the license verification search and enter the contractor's license number or name. Confirm the status is current and active, that the name matches the company you are hiring and that the license class covers your job. The record also shows public disciplinary history. The search takes about two minutes and is free.
Can a handyman install an air conditioner in Florida?
Not legally, unless they hold the appropriate state license. Installing or replacing an air conditioning system is contracting work that requires an air conditioning or mechanical license and a permit. Handymen may do minor tasks, such as replacing a filter, but refrigerant handling, electrical connections and system replacement need a licensed contractor.
What happens if I hire an unlicensed HVAC contractor?
The work likely will not be permitted or inspected, which can complicate resale, insurance claims and manufacturer warranty coverage. You may have limited options to recover money if the job goes wrong, and you could face liability if an uninsured worker is injured on your property. Correcting unpermitted work often costs more than doing it right the first time.
