How do you choose an HVAC contractor in Florida?
The right Florida HVAC contractor holds an active DBPR-certified license, carries liability and workers' comp insurance, pulls the permit, and bases the equipment size on a real load calculation — not a rule of thumb. Here is how to verify each of those before you sign.
An AC replacement is one of the largest purchases a Florida homeowner makes, and the contractor behind it matters as much as the equipment. A system installed by a licensed, insured, accountable crew with a permit and a proper load calculation will perform for years. The same equipment installed by an unlicensed, cash-only operation without a permit can fail early, void manufacturer warranties, and leave you with no legal recourse. This guide is the overview: what to check, what a complete quote looks like, the red flags that tell you to walk away, and where to go deeper on each topic.

Verify the Florida DBPR license first.
Every company installing or replacing a central air conditioning system in Florida must hold a certified air conditioning contractor credential from the Department of Business and Professional Regulation. The license carries a "CAC" prefix — for example, CAC1822797. A Class A certified contractor can work on systems of any size and the license is valid statewide. A Class B credential is capacity-limited. A local handyman registration is not a substitute for a certified CAC.
The license number on a business card or flyer proves nothing by itself. Look it up on myfloridalicense.com and read three things: the license type and class (certified air conditioning, Class A or B), the status (you want active — not null and void, delinquent, or inactive), and the qualifying agent name.
The qualifying agent is the licensed individual who is legally responsible for the company's work. The name on the license must connect to the business on your quote. "License borrowing" — where a sales outfit uses a credential that belongs to an unrelated party who never appears on the job — is a real problem in Florida's HVAC market. If the qualifier does not line up with the company asking for your money, that is a reason to stop. For a deeper walkthrough of this process, see our guide on how to verify an HVAC contractor license in Florida.
Insurance and EPA Section 608 certification.
An active license is necessary but not enough. Ask for proof of general liability insurance — so that property damage during the install does not become your problem — and workers' compensation coverage, or a valid exemption, so that an on-site injury does not land on the homeowner's policy.
There is also a federal certification specific to HVAC work. Under the Clean Air Act, any technician who opens a sealed refrigerant circuit must hold EPA Section 608 certification. It is a basic, verifiable credential. With refrigerants now transitioning from R-410A to R-454B, the ability to handle refrigerant correctly and legally is more important than ever — a crew cutting that corner is creating liability for the homeowner and the environment.
A legitimate company already has these documents on hand and produces them without resistance. Reluctance to provide them is itself a red flag.
Get more than one quote — and make them comparable.
A single quote gives you nothing to calibrate against. Getting two or three bids is standard practice for any significant home improvement, and AC replacement is no exception. The challenge is that quotes often are not apples-to-apples: one proposal might be for a 3-ton unit, another for 3.5; one might include the air handler, another might not; one might specify a high-efficiency unit, another a minimum-code unit.
Before comparing numbers, align the scope: same equipment tonnage and tier, same SEER2 efficiency rating, same line set and electrical work included, same permit commitment. If one contractor quotes a permit and another does not mention one, the second is not cheaper — it is incomplete, because a legal Florida AC replacement includes a mechanical permit pulled by the licensed contractor.
Once the scope is the same, the price comparison is real. A wide gap between quotes usually points to a scope difference, an equipment difference, or a corner being cut somewhere.
What a complete AC replacement quote must include.
A complete Florida AC replacement quote is not a line item and a total — it is a document with enough detail to understand what is being purchased and who is accountable for it. These are the elements that should be present.
<ul><li><strong>Manual J load calculation basis.</strong> The equipment size — tonnage — must come from a real load calculation for your specific home: square footage, insulation, window area, orientation, local climate data. A contractor who sizes by rule of thumb ("three tons for a two-thousand-square-foot house") is guessing. Undersized equipment runs constantly; oversized equipment cycles on and off too fast, leaving the home humid. Florida's climate makes this especially consequential. For more on sizing, see our guide on Manual J and AC sizing in Florida.</li><li><strong>AHRI-listed matched equipment.</strong> The outdoor unit and indoor air handler must be tested and listed together by the Air Conditioning, Heating, and Refrigeration Institute. An unmatched system may not perform at the rated efficiency or qualify for the manufacturer warranty.</li><li><strong>A permit pulled by the contractor.</strong> In Florida, the licensed contractor pulls the mechanical permit — not the homeowner. The permit triggers an inspection that confirms the install meets code. A quote that places permit responsibility on the homeowner is shifting liability; a quote that omits the permit entirely is a red flag.</li><li><strong>Duct scope.</strong> What is happening to the existing ductwork? Is it being inspected, sealed, repaired, or replaced? An install that ignores leaking or undersized ducts will underperform regardless of equipment quality.</li><li><strong>Written warranty terms.</strong> Parts warranty, labor warranty, and manufacturer warranty registration — who registers the equipment, what voids the coverage, and what does the contractor stand behind in writing. For a full checklist, see our Florida AC warranty checklist guide.</li></ul>

Red flags: what to walk away from.
Certain patterns reliably signal a bad outcome. Recognizing them before any paperwork is signed is the fastest way to protect yourself.
<ul><li><strong>Cash-only payment.</strong> A legitimate company accepts standard payment methods. Cash-only is designed to avoid accountability.</li><li><strong>No permit mentioned.</strong> Skipping the permit skips the inspection. It can also void the manufacturer warranty and create problems at resale.</li><li><strong>No load calculation.</strong> If the contractor sizes the system without measuring the home, the equipment guess may be wrong — and there is no professional basis to stand behind it.</li><li><strong>Suspiciously low flyer prices.</strong> A price dramatically below the market for a complete, permitted, quality install is usually not a deal — it is bait. The final invoice, scope, or quality will differ. See our guide on AC flyer bait-pricing in Florida for a closer look at how this works.</li><li><strong>High-pressure or "today-only" tactics.</strong> A legitimate contractor is not dependent on a rushed decision. Pressure to sign immediately, before you have compared quotes or verified the license, is a sales technique, not a service model.</li><li><strong>Door-to-door solicitation after a storm.</strong> Storm chasers are a known pattern in Florida. A licensed, established contractor does not need to knock on doors to find work.</li><li><strong>No written warranty.</strong> Verbal promises are not warranties. If it is not in writing with the contractor's name and contact on it, it does not exist.</li></ul>
Reviews and reputation: what to check and where.
Online reviews are useful context, but not all sources are equal. A contractor's own website testimonials are curated by the contractor. Google reviews, Yelp, and the BBB are harder to control and more representative. Check multiple platforms and look for patterns: consistent complaints about pricing surprises, permit problems, or warranty disputes matter more than a single outlier.
Also check DBPR for any disciplinary history or complaints on the license itself. A contractor with an active credential but a record of consumer complaints is worth researching further before engaging.
Word of mouth from neighbors who had an install in the last two or three years — and who know what was permitted and how the system has performed — is often more reliable than any review platform. Ask specifically: was a permit pulled, was there an inspection, has anything gone wrong since.
How NewHVACDeals helps you choose the right contractor.
NewHVACDeals was built around the things that protect a homeowner through a five-figure AC decision: license verification, a proper sizing basis, a transparent scope, and DBPR-certified crews behind every install.
The online intake collects your home's details before any contractor discussion begins — square footage, insulation, existing equipment, comfort complaints — so the sizing is based on your actual home, not a rule of thumb. The matching crew holds a Florida DBPR-certified air conditioning contractor credential, carries full liability and workers' compensation insurance, and pulls the permit on every job. EPA Section 608 certification is a baseline requirement for any technician handling refrigerant on our installs.
Because the scope and equipment are determined by intake rather than by a sales visit, there is no pressure to decide quickly and no upsell pressure at the door. The goal is a permitted, inspected, correctly sized install with written warranty terms — the things that make a new system perform and hold its value in a Florida home.
Frequently asked questions
- How do I check if an HVAC contractor is licensed in Florida?
- Go to myfloridalicense.com and search by license number or company name. Confirm the license type is a certified air conditioning contractor (CAC prefix), the status is active, and the qualifying agent listed matches the company on your quote. A license number on a flyer that does not resolve to an active, correctly classified credential is a reason to stop before any payment.
- How many AC quotes should I get?
- At minimum, two — preferably three. More important than the number is making them comparable: same tonnage, same SEER2 efficiency tier, same permit commitment, same scope of duct work and electrical. If the quotes are not scoped identically, the price comparison is not meaningful.
- What should an AC replacement quote include?
- A Manual J load calculation basis for the equipment size, AHRI-listed matched equipment (outdoor unit and air handler tested together), a contractor-pulled mechanical permit, a clear statement of what happens to the ductwork, and written warranty terms for both parts and labor. A quote missing any of these elements is incomplete.
- What are red flags when choosing an HVAC contractor?
- Cash-only payment, no mention of a permit, sizing without a load calculation, a suspiciously low advertised price relative to the market, high-pressure or today-only closing tactics, door-to-door solicitation, and no written warranty. Any one of these warrants caution; more than one is a clear signal to look elsewhere.
