Choosing an air conditioning company in Miami-Dade County comes down to a short list of checks you can finish before you sign: confirm the contractor’s state license is active, confirm the right insurance, and confirm the work will be permitted and built to the county’s hurricane code. Because all of Miami-Dade sits inside Florida’s strictest building zone, a few extra questions here protect you from problems a cheaper, unpermitted job would hide until you sell. This guide walks through each check in order.
TL;DR
Verify the contractor on Florida’s DBPR “Verify a Licensee” portal and confirm the record reads Current and Active with an air conditioning class, either CAC for a certified contractor or RA for a registered one. Confirm insurance meets the state minimum of $100,000 public liability and $25,000 property damage. Because Miami-Dade lies entirely within the High-Velocity Hurricane Zone, every replacement needs a mechanical permit (even a like-for-like swap), a Manual J load calculation, and equipment plus tie-downs carrying a current, HVHZ-valid product approval designed for a 175 mph wind. Get all of it in a written, itemized estimate. Hiring an unlicensed contractor is a crime in Florida and voids your access to the state recovery fund.
How do I verify an AC contractor’s license in Miami-Dade?
Start with the license, because every other protection depends on it. Florida licenses air conditioning contractors through the Department of Business and Professional Regulation (DBPR) under Chapter 489, and there are two things to read on the record: the class and the status.
Contractors are either certified or registered. A certified contractor, license prefix CAC, holds a state certificate of competency and may work anywhere in Florida, while a registered contractor, prefix RA, may work only in the local jurisdictions where they have met local requirements (Fla. Stat. 489.117). Both are legitimate; what matters is that the license is valid for Miami-Dade. The license is also graded by capacity: a Class A air conditioning contractor is unlimited, while a Class B is limited to 25 tons of cooling and 500,000 BTU of heating in any one system (Fla. Stat. 489.105).
To check, search the contractor by name or license number on the free DBPR Verify a Licensee portal. Read the status field: it must show Current for the primary status and Active for the secondary status. Codes for Probation, Suspended, or Inactive are not the same as active, and DBPR spells out exactly what each code means (Understanding DBPR Codes). A state certified contractor may work in unincorporated Miami-Dade on the state license, though incorporated cities can require additional local registration (Miami-Dade County licensing).
What insurance should an AC company carry in Florida?
An active license is only half the protection. Florida requires every certified or registered air conditioning contractor to carry a minimum of $100,000 in public liability coverage and $25,000 in property damage coverage (Fla. Admin. Code 61G4-15.003). Ask for a certificate of insurance and confirm those minimums are met. If a technician is hurt on your property or a mistake damages your home, this coverage is what stands between you and the bill.
Do not be talked into thinking a higher number is the legal standard. Some insurance and trade pages quote $300,000 in general liability, but that reflects common commercial contract requirements, not the licensing minimum, which remains $100,000 and $25,000 under the rule above.
Workers’ compensation is the second coverage to ask about. Florida requires construction businesses to carry workers’ compensation once they have one or more employees, and a contractor must collect proof of coverage or a valid exemption from any subcontractor on your job (Fla. Stat. ch. 440). A solo owner may instead hold a state-filed exemption, which is legitimate, so ask to see either the policy or the exemption.
Why choosing in Miami-Dade is different: the hurricane zone
Miami-Dade is not a normal air conditioning market, and the reason is the building code. The entire county sits inside the High-Velocity Hurricane Zone (HVHZ), the strictest tier of the Florida Building Code, which applies to only two counties statewide and covers all of Miami-Dade (HVHZ definition, Florida Building Code). In practice, three things should appear in any honest quote. The first is product approval: the outdoor equipment and its tie-downs must carry a current Miami-Dade Notice of Acceptance (NOA) or an HVHZ-endorsed Florida Product Approval, and you can look up any model yourself on the Miami-Dade Product Control Search or the statewide Florida Product Approval system. An approval that is expired or not HVHZ-rated fails inspection, and the equipment must be anchored to resist a 175 mph design wind speed for a typical home (FBC High-Velocity Hurricane Zone wind loads).
The second is the permit, and this is the rule homeowners are most often talked out of. In Miami-Dade, even an exact like-for-like change-out requires a mechanical permit; only the electrical permit is waived when the amperage does not change (Miami-Dade Permit Exemptions). A contractor who offers to skip the permit to save you money is offering uninspected work and the resale problems that follow it. The licensed contractor, not you, should pull it, because the homeowner owner-builder exemption is narrow and rarely appropriate for equipment work (Fla. Stat. 489.103).
The third is sizing by calculation, not guesswork. The Florida Energy Conservation Code requires the contractor or a Florida engineer to demonstrate proper sizing with a Manual J load calculation and a matched indoor and outdoor system, and the county checks the installed model against that calculation at final inspection (Florida Building Codes FAQ, energy code). If a company sizes a unit from your home’s square footage alone, that is a shortcut the code does not allow.
The Miami-Dade AC vetting checklist
Run every candidate through the same six checks before you sign. Each one is a legal requirement or a code standard, not a preference, and each can be confirmed from a primary source.
| Check | The standard to confirm | Where to verify it |
|---|---|---|
| DBPR license is active | The contractor holds a certified (CAC) or registered (RA) air conditioning license that reads Current and Active | DBPR Verify a Licensee, status codes per Understanding DBPR Codes |
| Insurance meets the state minimum | At least $100,000 public liability and $25,000 property damage | Fla. Admin. Code 61G4-15.003 |
| Quote includes a Manual J load calculation | Sizing is shown by a Manual J calculation and a matched system, not square footage | Florida Energy Conservation Code, section 101.4.7 |
| Equipment and tie-downs carry HVHZ product approval | The exact condenser, air handler, and tie-down models hold a current, HVHZ-valid NOA or Florida Product Approval | Miami-Dade Product Control Search |
| Contractor pulls the mechanical permit | A mechanical permit is pulled under the contractor’s license, required even for a like-for-like swap | Miami-Dade Permit Exemptions |
| You receive a written, itemized estimate | The estimate lists the exact equipment make and model and the Manual J sizing, so the two checks above can be confirmed on paper | Miami-Dade Product Control Search |
The stakes for skipping the first check are set by statute. Unlicensed contracting in Florida is a first-degree misdemeanor for a first offense and a third-degree felony for a repeat offense or any offense committed during a Governor-declared state of emergency, such as a hurricane (Fla. Stat. 489.127). DBPR can add an administrative fine of up to $10,000 (Fla. Stat. 489.13). Just as important for you, a contract with an unlicensed contractor cannot be made whole by the state: the Florida Homeowners’ Construction Recovery Fund only compensates losses caused by licensed contractors (Fla. Stat. 489.140).

Frequently Asked Questions
How do I verify an AC contractor’s license in Miami-Dade?
Search the contractor by name or license number on Florida’s free DBPR Verify a Licensee portal, then read two fields. The license class should be an air conditioning type, shown as a CAC prefix for a certified contractor or RA for a registered one, and the status must read Current for the primary status and Active for the secondary status. A certified CAC license is valid statewide, while a registered RA license is valid only where local requirements were met, so confirm it covers Miami-Dade. The check is free and takes a few minutes, so save a copy of the record before any work begins.
Does an AC company need a permit for a simple change-out in Miami-Dade?
Yes. Because Miami-Dade lies entirely within the High-Velocity Hurricane Zone, replacing central air conditioning equipment requires a mechanical permit even when it is an exact, like-for-like swap. The only permit waived for a same-amperage change-out is the electrical permit, not the mechanical one. The licensed contractor pulls that permit under their own license, and it triggers the rough and final inspections that confirm the equipment, anchorage, and sizing meet code. A contractor who suggests skipping the permit is asking you to accept uninspected work that can resurface as a problem when you sell the home.
What insurance and license details should I ask an AC contractor for?
Ask for the contractor’s DBPR license number, verify it reads Current and Active, and confirm the class is air conditioning rather than an unrelated trade. Then ask for a certificate of insurance showing at least $100,000 in public liability and $25,000 in property damage, which is the Florida minimum for air conditioning contractors. Also ask for proof of workers’ compensation coverage or a valid state-filed exemption, since a business with employees must carry it. A legitimate company provides all of this without hesitation, and any refusal to share a verifiable license number is a reason to keep looking.
How do I know the AC equipment is approved for Miami-Dade’s hurricane code?
Ask the contractor for the exact make and model of the proposed condenser, air handler, and tie-down hardware, then look each up on the Miami-Dade Product Control Search or the statewide Florida Product Approval system. Confirm the approval has not expired, lists your exact model, and is valid for the High-Velocity Hurricane Zone. The equipment and its anchorage both need approval, and an approval that is expired or not HVHZ-endorsed will fail inspection. Miami-Dade requires this because the county designs residential equipment to withstand a 175 mph wind, a standard set after Hurricane Andrew.
What happens if I hire an unlicensed AC contractor in Florida?
You take on both legal and financial risk. Unlicensed contracting is a crime in Florida, a first-degree misdemeanor for a first offense and a third-degree felony during a declared state of emergency such as a hurricane, and DBPR can impose an administrative fine of up to $10,000. For the homeowner, the practical damage is worse: the work may go unpermitted and uninspected, insurance and warranty claims can be denied, and the Florida Homeowners’ Construction Recovery Fund, which can reimburse losses caused by a licensed contractor, does not cover contracts with unlicensed ones. The little saved up front is not worth losing every one of those protections.
