Before you hire an HVAC contractor in Kendall, check the license. A fast answer and a polished website do not tell you who is qualified to work on your AC.
Perhaps your air conditioning stopped during a summer afternoon. Or a replacement quote just landed on your kitchen table, and the total makes you wince. You search on your phone and find a wall of ads. Everyone promises “24/7 service” and “honest pricing.” You still need to know who is licensed, who carries insurance, and who will answer when the same problem returns.
A rushed hire can cost more than an expensive repair. In Florida, contracting without the required license is a criminal offense. State law also generally prevents an unlicensed contractor from enforcing a contract for work that required that license. Those protections do not mean recovering your deposit will be quick or easy.
Pay a large deposit without a clear scope, a start date, or a plan for required permits, and you could still be sitting in a hot house while chasing someone who no longer answers.
Start with the checks, before you pay.
This guide gives you a 10-minute first screening you can run on your phone: look up the license, request insurance evidence, and check available complaint and disciplinary records. Then, for a planned replacement, compare three written quotes and agree on payment terms tied to clear milestones.
Whether you are a Kendall homeowner facing an emergency, planning a replacement, or a landlord arranging a repair, the steps below help you decide who passes and when to move to the next number. We also cover emergency callouts, system sizing, current rebates, and where to turn if something goes wrong, with Kendall and Miami-Dade in mind.
Start Here: Which Situation Are You In?
Answer these three questions to find your next step. If more than one applies, start with the deposit check.
Select any question that applies to your situation to find your next step.
More than one may apply.
Start with section 7 for emergency guidance, then read section 2.
Read sections 4 and 5 before choosing your replacement.
Start with section 6 before deciding on the deposit.
Where Should You Start?
1. Is your system down right now?
2. Are you replacing a system 10+ years old?
3. Did a contractor already ask for a deposit?
At a Glance: The 10-Minute Check
Use this table for a first screening. Collecting insurance documents and comparing replacement quotes will take longer.
| Check | Where to do it | Pass looks like | Fail or red flag |
|---|---|---|---|
| Active license | Florida’s Department of Business and Professional Regulation (DBPR); Miami-Dade contractor records | An active license covering the proposed work, with the qualifying contractor linked to the business on your contract | No verifiable license, inactive status, or only a business tax receipt |
| Insurance | Request the certificate; confirm with the insurance agency and check Florida workers’ compensation records | Current liability coverage and verified workers’ compensation coverage, or a valid exemption applicable to the person claiming it | “We’re covered,” without documents; expired coverage; an exemption offered as proof that everyone is covered |
| Complaints | DBPR and Miami-Dade records; BBB as an additional check | Available records reviewed, with any complaints or disciplinary action explained and considered | Repeated reports of deposits taken, unfinished work, or unresolved problems |
| Written quote and sizing | Request from each contractor before signing | Model numbers, cooling capacity, efficiency rating, ductwork scope, warranties and dates; a documented sizing calculation for replacement | A one-line price, missing equipment details, or “same size as the old one” without assessing the home |
| Permit | Confirm with the building department responsible for your address | Contractor obtains the required permit, provides its number and arranges inspections | Offers to skip a required permit or asks you to obtain it to make the job “cheaper” |
| Payment terms | Written contract | Limited initial payment, progress payments tied to work completed, and final payment after completion and any required final inspection | Large unexplained advance, cash-only demands, or payment to an unrelated person |
A CAC number is one valid license type not the only one. CAC means Certified Air Conditioning Contractor. Florida also has registered air-conditioning contractors and other license categories. Check the permitted work and geographic scope, along with the license status.
For insurance, verify the documents rather than relying on a website badge. Florida provides both workers’ compensation coverage and exemption searches. An owner’s exemption does not establish coverage for the whole crew.
No complaints found does not guarantee a good hire. Treat the complaint search as one check alongside the license, insurance and written scope.
For a replacement quote, tonnage means cooling capacity. SEER2 is a standardized cooling-efficiency rating. Manual J is a method for calculating how much heating and cooling a home needs.
Permit requirements depend on the work and the jurisdiction. Miami-Dade requires permits for regulated mechanical installations and replacements, while some work has exemptions. Confirm with the responsible building department if a contractor says yours needs none.
Miami-Dade advises homeowners to limit upfront payments, match progress payments to completed work, and obtain proof of the final inspection before making final payment. A personal check you write to the contracting business is different from a request to make it payable to an unrelated individual.

2. The 10-Minute License Check
A number on a van is a starting point. Verify it before anyone works on your system.
Miami-Dade warns that a business tax receipt sometimes called an occupational license is not a contractor license. It shows a business tax registration, not permission to perform licensed HVAC work.
Contracting without the required license is a criminal offense in Florida. State law also generally prevents an unlicensed contractor from enforcing a contract for work requiring that license. That does not make hiring one safe or guarantee you will recover money paid.
Run these five steps before authorizing work.
1. Get the Company Name and License Number
Ask by phone or text:
“What is the full business name, contractor license number and name of the licensed qualifier?”
The qualifier is the licensed person responsible for qualifying the contracting business. That person may be different from the technician arriving at your door.
Save the reply. Compare it with the quote and contract. Miami-Dade advises checking for the contractor’s license information on vehicles, contracts and business cards.
Refuses to give the number? Fail. Next number.
2. Search the State Record
Open the DBPR license search. Choose the license-number search, enter the number provided, and open the matching record.
Check:
- Status: Look for “Current, Active.”
- License type and class: Confirm they cover your proposed work.
- Expiration date: Check that the license remains current.
- Business connection: Look for the business qualified by that licensee.
- Discipline: Review available complaint or disciplinary links and read any orders.
“Current, Inactive” does not authorize active practice. “Delinquent, Active” means the license was not renewed on time; DBPR says the contractor cannot practice until the status is updated.
CAC means Certified Air Conditioning Contractor. It is not the only valid prefix: RA identifies a registered air-conditioning contractor, while CMC identifies a certified mechanical contractor. Check the scope, not just the letters.
3. Search the Miami-Dade Record
Open the Miami-Dade Contractor Inquiry and Complaint Search, select Contractor Search, and enter the company name or license number.
Review the contractor record and available complaints. If the result is missing, unclear, or does not establish current insurance, contact County Contractor Licensing using the tools table below. The county can help verify licensing, complaints, liability insurance and workers’ compensation information. Confirm insurance documents separately before work begins.
You can browse contractors in Kendall to build a shortlist. Run these checks on each business before hiring.
4. Match the Business, Qualifier and Payee
Different names need a verified connection.
A license may show an individual qualifier and a separate business name. That can be legitimate: DBPR requires contractors to qualify the businesses they operate.
Confirm that the qualifier is linked to the business on your contract. Make payments to that contracting business. If a trading name differs, ask for documentation explaining the connection.
“I work under my cousin’s license” is not proof. Neither is an active license belonging to an unrelated contractor.
5. Check the License’s Limits
Certified contractors can work statewide within their licensed scope. Registered contractors have geographic limits; confirm authorization for your address.
For air-conditioning licenses, Class A has no cooling-capacity limit. Class B covers systems up to 25 tons of cooling and 500,000 BTU per hour of heating. Class C has a narrower service scope. For replacement, verify Class A, Class B or another appropriate license covering the complete job. These are scope categories, not quality rankings.

Check which work requires licensing
| Line item | Quote A |
|---|---|
| Company and license number | |
| Equipment brand and model numbers | |
| Cooling capacity: tonnage | |
| SEER2 rating | |
| Indoor and outdoor units both replaced? | |
| Load calculation included; results supplied? | |
| Ductwork: inspection, sealing or replacement | |
| Thermostat model and installation | |
| Permit fees and inspections included? | |
| Old equipment removal and disposal | |
| Parts and labor warranties; exclusions | |
| Start date and expected duration | |
| Deposit and payment milestones | |
| Quote expiration date |
Resolve the Blanks Before Comparing Totals
“Not stated” does not mean included.
Send each contractor the missing items and request a revised written quote. “Ductwork included,” for example, needs an explanation: inspection only, sealing specific sections, or replacing ducts? Those are different jobs.
Separate the manufacturer’s parts warranty from the contractor’s labor warranty. Ask who pays for diagnosis, labor and other charges if a covered part fails. ENERGY STAR identifies warranty comparison as part of reviewing bids.
If one proposal recommends a different system size, ask for the calculation behind it. Do not choose capacity by majority vote.
Choose the Complete Bid You Can Verify
Broad online price ranges cannot tell you what your Kendall installation should cost. Your written bids provide the useful comparison but only after the scope is clear.
If one bid is far lower, ask what it leaves out before you celebrate.
Check equipment, permits, ductwork, disposal and labor coverage. Ask whether additional work requires your written approval. Then weigh the complete price alongside verified credentials, references and the proposed schedule.
To build your shortlist, browse the Kendall local business directory, then apply the same checks to every company.
5. Sizing, SEER2 and Rebates: What to Ask For
A bigger unit is not automatically a better unit. Ask how the contractor decided on the size.
“Your neighbor has a four-ton system” does not answer that question. Neither does copying the old unit’s capacity without assessing your home.
Ask for the Calculation Behind the Size
An ACCA Manual J load calculation estimates how much heating and cooling your specific home needs. It considers features such as windows, insulation, orientation and air leakage. ENERGY STAR recommends that contractors verify system size using Manual J.
Ask:
“Will you provide the load calculation and explain how it supports the equipment you selected?”
Florida’s residential energy code addresses equipment sizing in Section R403.7.1. It uses Manual S, the equipment-selection method, with loads calculated through Manual J or another approved methodology. Ask the contractor which requirements and any replacement exceptions apply to your job.
Pass looks like a documented assessment and an explanation you can follow. If the contractor proposes more capacity, ask what changed: the home, the calculation, or the assumptions.
Check the Actual SEER2 Rating
SEER2, or Seasonal Energy Efficiency Ratio 2, measures cooling efficiency under a standardized test. Higher ratings indicate greater rated efficiency, but the rating alone does not predict your electricity bill.
Florida belongs to the Southeast region. For ordinary split-system central air conditioners installed on or after January 1, 2023, the minimum depends on certified cooling capacity.
| Standard or program | Number to check | Source |
|---|---|---|
| Southeast split-system AC below 45,000 BTU/hour | Minimum 14.3 SEER2 | DOE; Miami-Dade advisory memo |
| Southeast split-system AC at or above 45,000 BTU/hour | Minimum 13.8 SEER2 | DOE; Miami-Dade advisory memo |
| FPL qualifying AC replacement | 15.2 SEER2 or higher; $200 rebate, with other conditions | FPL |
Do Not Budget for the Expired Federal Credit
For a system placed in service in 2026, do not count on the federal Section 25C heat-pump credit. IRS guidance confirms that the credit ended for property placed in service after December 31, 2025. Older articles promising it for later installations are out of date.
Before signing, put the model numbers, system rating, rebate eligibility and invoice credit in writing. A verbal promise should not be part of your budget.
6. Permits, Deposits and When to Pay
Do not hand over a large deposit while the permit question remains unanswered.
The contractor says a permit is “not needed” and asks you to pay today. You want the AC working, so agreeing feels easier than checking.
That shortcut can leave required work outside the permit and inspection process. It may also create questions when you sell or arrange later repairs. A promise that “we do this all the time” does not establish an exemption.
Follow these steps before paying.
1. Confirm Who Obtains the Permit
An AC system replacement generally requires a mechanical permit. Miami-Dade requires permits for regulated mechanical installations and replacements, with exemptions for certain work. Confirm your exact scope with the responsible building department.
For a property in unincorporated Kendall, start with Miami-Dade Regulatory and Economic Resources. Check the jurisdiction for your address; a “Miami” mailing address alone does not identify the permitting authority.
Ask the contractor:
“Will you obtain the permit, include its cost in the quote, and give me the number before permitted work begins?”
Use the county’s permit guidance and permit search to verify the record. Check the address, scope and contractor. Miami-Dade flags requests for homeowners to obtain permits as a warning sign.
2. Understand What the 10% Threshold Means
The 10% threshold is not a deposit cap.
Under Florida Statute 489.126, an initial payment exceeding 10% of a residential contract triggers these deadlines:
| Action | Statutory deadline |
|---|---|
| Apply for required permits | Within 30 days after payment |
| Start work | Within 90 days after all necessary permits are issued |
The statute allows longer periods agreed in writing and recognizes just cause for failing to apply, start or refund. Permit-exempt work does not require a permit application.
A payment below that threshold still deserves scrutiny. Ask what the deposit purchases, when equipment will arrive, and which completed milestones trigger later payments.
3. Use the Written-Demand Procedure if Work Stalls
If the contractor misses those requirements, the statute specifies a written demand to apply for permits, start work or refund payment. Send it by certified mail, return receipt requested, to the contract address. If none exists, use the applicable licensing address.
Failure to act within 30 days after receiving the demand can support an inference of no just cause. Violations can carry criminal penalties under the current statute; delay alone does not guarantee prosecution or repayment.
Keep the letter, delivery evidence and payment records. For hiring or replacing a contractor, use the directory to find candidates, then verify that they are licensed contractors through the agency lookups.
4. Make Every Payment Traceable
Pay the contracting business by check or card and obtain a receipt. Avoid cash or requests to pay an unrelated individual. Miami-Dade identifies those requests, along with large upfront payments, as warning signs.
Get changes and their prices approved in writing before paying for extra work.
5. Check Completion Before Paying the Balance
Agree in the contract that final payment follows completed work and approval of required final inspections.
Miami-Dade also advises requesting final lien releases from firms supplying labor or materials, especially those that sent a Notice to Owner. Inspection approval does not prove those firms were paid.
Request the contractor’s final payment affidavit where applicable under Florida’s lien law. It identifies whether lienors remain unpaid.
Put permit responsibility, application and start dates, payment milestones, and closeout documents in the contract.
7. When It’s an Emergency: Vetting in Three Minutes
Move quickly, but check who you are hiring before authorizing work.
The AC stops at night. The house is getting warmer, and every search result promises “24/7 service.” You call the first company that answers. Suddenly, you are agreeing to charges without knowing who will arrive or what the visit includes.
Miami-Dade warns homeowners against letting urgency replace checks on a contractor’s qualifications. A quick license lookup still belongs in an emergency call.
Test the “24/7” Promise
An answered phone is not a confirmed technician.
Read the service hours and ask whether “24/7” means telephone support, dispatch or actual repair visits. Then ask:
“When can a technician be at my Kendall address tonight?”
Get an arrival window. Ask whether it is confirmed, what happens if the technician is delayed, and whether the company can diagnose your type of system. “We’ll get someone out” leaves too much unanswered.
Run This Three-Minute First Screen
- Get the license number and look it up. Confirm current, active status and the connection to the business taking your booking. If you cannot verify it, pause. Three minutes is a target, not a reason to skip an unclear record.
- Confirm the visit charges in writing. Ask for the diagnostic fee, any after-hours surcharge, and whether the diagnostic fee is credited toward an approved repair. Request a text or email before dispatch. After diagnosis, get the repair scope and total price before work starts. A visit fee is not approval for additional work.
- Confirm who is coming and when. Ask whether the technician works for the booked company or another business. Request their name and arrival window. Ask for insurance evidence, and use a traceable payment method to the contracting business. Avoid cash.
Miami-Dade advises obtaining written terms before payment and identifies cash demands or payments to an individual instead of the contracting company as warning signs.
You can authorize diagnosis without authorizing a replacement.
If the recommendation becomes a major purchase, ask whether a safe temporary option exists while you compare replacement quotes. Do not let the late hour make that decision for you.
Prepare Before the Next Breakdown
ENERGY STAR recommends annual preseason cooling and heating checkups. That can mean separate spring and fall visits, depending on your equipment and maintenance needs.
If a maintenance agreement offers “priority service,” ask for its meaning in writing: response target, weekend coverage, extra charges and exclusions. Priority is useful only when you know what the company promises.
Save one vetted contractor’s number before summer. Keep its license details, service hours and emergency booking terms with it. That gives you a checked starting point when the house is hot.
9. If Something Goes Wrong: Who to Call, in Order
Start with a written record. Then contact the agency that handles the problem. You do not have to finish every step before seeking legal help.
- Write to the contractor. Describe the problem, the remedy you want and the relevant dates. For a deposit dispute covered by Section 489.126, follow its formal demand procedure: certified mail, return receipt requested, to the address in the contract. If no address is listed, use the applicable licensing address. Keep the letter and delivery evidence. An ordinary text message does not replace that statutory procedure.
- Contact Miami-Dade Contractor Enforcement. For abandonment, suspected violations or unlicensed work, use the county’s Contractor Enforcement page. Its published contact is 786-315-2424. For license and insurance questions, Contractor Licensing lists 786-315-2880. Send the contract, payment evidence, photos and permit information. Ask which issues fall within the agency’s authority.
- File with Florida DBPR where applicable. Report a state-licensed contractor through DBPR’s complaint process. DBPR also accepts reports of unlicensed activity. Its Customer Contact Center is 850-487-1395. Include the license number, a dated account of events and supporting documents. Filing a regulatory complaint does not guarantee a refund.
- Check Recovery Fund eligibility. A qualifying judgment, award or restitution order against a licensed contractor may support an application, subject to collection efforts, deadlines and other rules. The fund is a last resort, not an automatic next payment.
- Consider the Better Business Bureau early. BBB can help seek a business response and provide complaint information for cross-checking. It has no regulatory power. Do this before litigation where appropriate: BBB generally excludes complaints already in litigation or resolved by court action, arbitration or settlement.
- Speak with a construction attorney when significant money is involved. Get advice promptly for substantial deposits, property damage, lien notices or disputed termination. You need not wait for agency complaints to conclude.
Frequently Asked Questions
How do I check if an HVAC contractor is licensed in Kendall?
Search the DBPR license record, then use the Miami-Dade contractor search. Confirm current, active status, the scope of work and the qualifier’s connection to the business on your contract. CAC identifies a certified air-conditioning contractor, but other appropriate license types exist, including registered air-conditioning and mechanical contractor licenses.
Is a business tax receipt the same as a contractor license?
No. A business tax receipt or occupational license does not authorize someone to perform licensed HVAC work. Miami-Dade specifically warns homeowners against accepting it as a contractor license. Ask for the contractor license number and verify it independently.
How many HVAC quotes should I get?
For a planned replacement, aim for at least three written quotes following on-site assessments. Compare the equipment, scope, efficiency, warranties and complete installed price. ENERGY STAR recommends home evaluations and itemized estimates. For a small repair or tune-up, one vetted contractor may be enough; consider a second opinion for an expensive or poorly explained repair.
How much deposit can an HVAC contractor ask for?
The 10% threshold in Florida Statute 489.126 is not a deposit cap. An initial payment exceeding 10% of a residential contract generally triggers a requirement to apply for necessary permits within 30 days and start work within 90 days after all necessary permits are issued. Written extensions and just-cause exceptions apply. Negotiate payments tied to clear milestones rather than treating any requested deposit as reasonable.
Do I need a permit to replace my AC in Kendall?
Generally, yes. A system replacement normally requires a mechanical permit. Confirm the scope and jurisdiction with the building department responsible for your address. Have the contractor obtain required permits, provide the permit number and arrange inspections. Some minor work is exempt; verify an exemption rather than accepting a verbal assurance.
How long does an AC last in Kendall?
HVAC.com’s March 2025 guide estimates 10–15 years for Florida systems. That is an industry range, not a Kendall-specific measurement or a guarantee. Maintenance, installation, sizing and use affect lifespan. At 10 years, ask about the system’s condition and compare repair with replacement when problems become costly or frequent.
Is there still a federal tax credit for a new AC or heat pump?
Section 25C does not cover equipment placed in service after December 31, 2025. Do not include that credit in a 2026 installation budget. As checked October 6, 2026, FPL lists a $200 instant rebate for qualifying residential AC replacements installed by a participating contractor. Confirm equipment eligibility and participation before purchasing.
Do “24/7” HVAC companies really come at night?
The claim alone does not establish an arrival time. Ask whether it means phone support, dispatch or technician visits. Request a confirmed arrival window for your Kendall address and written diagnostic and after-hours charges. Approve the repair price separately after diagnosis.
Before You Hire, Run the Check
A hot house and an unfamiliar quote can make the first available contractor feel like the only choice.
The checks in this guide give you a better basis for deciding: a verified license, documented insurance, comparable replacement bids, required permits and clear payment terms. You still have a decision to make, but you have records behind it.
Run the 10-minute check on every contractor, every time.
For a planned replacement, choose two or three companies, verify their credentials and request written on-site quotes. For an emergency, start with the license, arrival window and visit charges.
