Hiring an unlicensed AC contractor in Florida can void your equipment warranty, complicate an insurance claim if the work fails, and leave you fully responsible for fixing a bad install with no recourse. Checking a license takes about five minutes if you know where to look and what the result actually means.
- Verify an ac contractor license in Florida for free at MyFloridaLicense.com before signing any proposal in 2026.
- A.R. Williams Air Conditioning holds a Certified Air Conditioning Contractor license, which covers work statewide, not just locally.
- Registered contractors can only legally work in the county or city that issued their license, not statewide.
- A license number missing from your written proposal is a bigger red flag than a hard-to-find number.
Why this matters
Florida requires anyone installing, repairing, or replacing a central AC system to hold a state contractor license, either Certified or Registered. Florida Statute 489.127 makes contracting without one a criminal offense, not just a paperwork problem you settle in small claims court later.
Here's the part homeowners don't think about until it's too late: if an unlicensed contractor botches a refrigerant line or wires a new air handler wrong, most manufacturer warranties on the equipment are void from the start. Your homeowner's insurance carrier can also deny a related claim if they find out the work wasn't done by a licensed contractor pulling proper permits.
This isn't about distrust. Most companies quoting AC work in Palm Beach, Martin, and St. Lucie counties are exactly who they say they are. But the two or three that aren't tend to look and sound identical to the ones that are, right up until the job goes sideways. A.R. Williams Air Conditioning is a Ruud Pro Partner, Carrier Authorized Dealer, and Daikin Comfort Pro, and every technician can produce a license number without hesitation. That's the standard to hold anyone quoting your home to.
What you'll need
- The contractor's exact license number, not just a company name
- Five minutes on a phone or laptop
- Access to MyFloridaLicense.com, the Department of Business and Professional Regulation's public license search
- The business name exactly as it appears on the written proposal
- Your county building department's contact info, if you want to confirm permit history separately
The steps
1. Ask for the license number before the estimate
A licensed contractor gives you their license number without checking a truck decal or calling the office. It's usually formatted like CAC1234567 (Certified) or RA0012345 (Registered).
Asking early accomplishes two things: it screens out anyone unprepared to answer, and it gives you the exact string you need for the next step. If someone hedges or says "we're licensed and insured" without a number, that's your first flag.
Common mistake: accepting a license number for the parent company when a subcontractor or franchisee is actually doing the work.
2. Search the license on MyFloridaLicense.com
Go to the DBPR's public search tool and enter the license number directly rather than searching by name. Names produce multiple results and make it easy to match the wrong record.
The search returns the license holder's name, license type, status, and the address on file. This step alone weeds out expired licenses, licenses under a different individual's name, and numbers that don't exist at all.
Expected outcome: a single match showing "Current, Active" status tied to a real name and address.
3. Match the license type to the job
Florida issues two relevant license classes for AC work: Certified Air Conditioning Contractor, which allows work anywhere in the state, and Registered contractors, who can only legally operate in the specific county or municipality that issued the license.
If a contractor based two counties away tells you they're "Registered," that's worth a direct question about where that registration is valid. This detail matters more in South Florida than most places, since Palm Beach, Broward, and the Treasure Coast sit close enough together that companies cross county lines constantly.
4. Confirm "Current, Active" status, not just "found"
A license showing up in the search isn't the same as a license in good standing. DBPR records also show statuses like Delinquent, Inactive, Suspended, and Null and Void.
Delinquent usually means unpaid renewal fees, not a suspension, but it still means the person is not currently licensed to work. Read the status field carefully instead of stopping at "it exists."
5. Confirm the business name matches
The name on the DBPR record should match, or clearly connect to, the business name on your proposal, invoice, and truck. A mismatch isn't automatically a scam, sometimes it's a DBA or a recent ownership change, but it's worth a direct question before you sign.
“A license number that isn’t on your written proposal is a bigger red flag than a number that’s hard to find.”
6. Verify insurance and workers' comp separately
A valid contractor license doesn't automatically mean current general liability insurance or workers' compensation coverage. Ask for a certificate of insurance directly, and call the insurer listed on it if anything feels off.
This step protects you specifically: if an uninsured worker is injured on your property, you can end up named in the claim. A company confident in its coverage produces the certificate without pushback.
7. Ask who's pulling the permit
Any full AC replacement in Palm Beach, Martin, or St. Lucie County requires a mechanical permit, and permitting rules differ slightly by county. The licensed contractor, not you, should be pulling it under their license number.
A contractor who suggests skipping the permit "to save time" is asking you to skip the inspection that catches sizing errors, bad electrical connections, and code violations before they become your problem. Get a second opinion if a quote seems built around avoiding that step.
8. Get the license number written into the proposal
Once everything checks out, ask for the license number printed on the written estimate or contract itself, not just mentioned verbally. This turns a verified fact into a paper trail if anything is disputed later.
Expected outcome: a proposal you could hand to your county's building department and have it match cleanly against the permit application.

Troubleshooting
License search comes back "Delinquent." Ask when it lapsed and for proof it's since been renewed. A contractor who renewed last week and hasn't updated their paperwork is different from one who's been lapsed for a year.
The business name on the truck doesn't match the license record. Ask directly whether it's a DBA, a franchise, or a subcontracted crew. Get the answer in writing before work starts, not after.
They say they're insured but won't produce a certificate. This is one of the more common gaps found after a bad install. No certificate within a day of asking is a reasonable reason to walk.
No permit was pulled for a full system replacement. This shows up most often in older homes across South Florida, some still running R-22 systems installed before 2010, where a "like for like" swap gets treated informally. Full replacements still require a permit regardless of the home's age.
The license holder's address is out of state. Florida allows reciprocity in some cases, but the license still has to be active and appropriate for the work. If the address doesn't match the business doing the work in your home, ask why before signing.

What to do next
Once you've confirmed the contractor is legitimate, the next question is usually whether the system actually needs repair or full replacement. That decision changes the scope, the permit, and the price, so it's worth reading through before you approve anything in 2026.
FAQ
How do I verify an AC contractor’s license in Florida?
Search the exact license number on MyFloridaLicense.com, the DBPR’s public database. Confirm the status reads Current and Active and that the name matches the business quoting your job.
Is it illegal to hire an unlicensed AC contractor in Florida?
Yes. Florida Statute 489.127 makes contracting for regulated work without a license a criminal offense, and it also puts your equipment warranty and insurance coverage at risk.
What’s the difference between a Certified and a Registered AC contractor in Florida?
A Certified Air Conditioning Contractor can legally work anywhere in Florida. A Registered contractor is limited to the specific county or city that issued the license.
Does a licensed contractor always pull a permit for AC replacement?
A full system replacement requires a mechanical permit in Palm Beach, Martin, and St. Lucie counties. A licensed contractor should pull it under their own license number, not skip it.
Can I check if a contractor has complaints filed against them in Florida?
Yes, the DBPR license search shows disciplinary history alongside license status. Any active complaints or past disciplinary action show up on the same record.
Does a license number on a truck or website count as proof?
No. Anyone can print a number on a decal. Confirm it directly on MyFloridaLicense.com rather than trusting what’s printed on a vehicle or website.
What happens if my AC contractor turns out to be unlicensed?
You have limited legal recourse, the manufacturer warranty on the equipment is likely void, and your insurer may deny related claims. Report it to the DBPR and get a licensed contractor to inspect the work before using the system again.
One last thing
The DBPR license search shows disciplinary history in the same record as license status, most homeowners never scroll down far enough to see it. A clean license with zero complaints on file is worth more than any sales pitch about experience or reviews, because it's the one thing a contractor can't spin.
