What the Law Actually Requires in Florida

The State License: Florida DBPR Class A vs. Class B

Florida's HVAC contracting rules live in Chapter 489, Part II of the state statutes. The Construction Industry Licensing Board, which sits inside the DBPR, issues two main classes of air conditioning contractor licenses that cover residential replacement work.

A Class A Air Conditioning Contractor can work on heating and cooling systems of any size, with no scope limit. A Class B Air Conditioning Contractor is capped at 25 tons of cooling capacity and 500,000 BTU of heating capacity per unit. For nearly every single-family home in Clermont, including the older houses near the Chain of Lakes and the master-planned communities along Highway 27, a Class B license covers the scope of work cleanly.

A legitimate state-certified contractor's license number starts with “CAC” followed by seven digits. Ask for that number in writing before signing anything. There's also one more distinction worth getting straight. A State Certified contractor passed the DBPR statewide exam and can work anywhere in Florida. A State Registered contractor passed only a local competency exam and can work just in the jurisdictions that recognize it. Either is legal here as long as the registration covers Lake County, but Certified is the cleaner credential to look for.

EPA Section 608: A Federal Certification, Not a State License

The state license tells you the contracting business can legally pull a permit and bid on the job. EPA Section 608, set under the federal Clean Air Act, is a separate certification that any individual technician handling refrigerant has to hold personally.

There are four 608 certification types. Type I covers small appliances. Type II covers high-pressure systems, which is what most residential central AC and heat pumps run. Type III covers low-pressure. Universal covers all three. For a Clermont system replacement, the technician brazing in the new lines or recovering refrigerant from the old unit needs at least Type II, or Universal.

We see this mix-up a lot. A Florida HVAC license doesn't include EPA 608 by default. The contracting business holds the state license, while the technicians on the truck hold their own 608 cards as individuals. Both have to be in order before refrigerant moves on your property. If a quote comes in well below market and the company is vague about who will actually be on the truck, ask for the lead tech's 608 card type. A licensed company that puts uncertified labor on a refrigerant job is a fast path to refrigerant venting into the atmosphere, you inheriting the liability, and a brand-new system starting its life with an undocumented charge.

Insurance, Bond, and Workers' Comp: What to Ask For in Writing

Florida sets minimum insurance thresholds for licensed HVAC contractors. General liability coverage has to be at least $100,000 per occurrence with $25,000 in property damage coverage. Florida also requires workers' compensation for any contractor with employees, unless the contractor holds a formal exemption issued within 30 days of the license going active.

A Clermont system replacement puts crews on the roof, in attics that hit 130 to 140 degrees in summer, and in tight spaces around live electrical. If a worker gets hurt on an uninsured job site, or if equipment damages your home during the swap-out, the liability path runs straight through you when the contractor isn't covered.

Licensed contractors also pass a financial-responsibility check at the time of licensure: a FICO score of 660 or higher, completion of a 14-hour DBPR-approved course on financial responsibility, or a licensing bond. You won't see any of this on the truck, but you can verify all of it on the certificate of insurance and the public DBPR record. Before any replacement contract is signed, ask for a current certificate of insurance naming you as the property owner, and ask for the workers' comp policy number or the formal exemption letter. Anyone who hesitates on these requests has already told you something.

Permits, Voluntary Credentials, and the 60-Second License Check

Almost every system replacement in Clermont requires a permit issued by City of Clermont Building Services or the Lake County Building Division, depending on the property's location. Only a licensed contractor can pull that permit and request the inspection that closes the job. A contractor who offers to skip the permit “to save you money” is offering you unpermitted work, which can surface during a future appraisal, home sale, or insurance claim.

Beyond the statutory minimum, a few voluntary credentials genuinely matter. Technicians earn NATE certification (North American Technician Excellence) by passing rigorous installation and service exams. ACCA membership (Air Conditioning Contractors of America) signals the contractor follows industry-standard load-calculation and ductwork-sizing practices. An ENERGY STAR Certified Installer is a contractor the federal efficiency program has approved to install qualifying equipment, which matters for utility rebates and federal tax-credit eligibility.

Verifying a Florida HVAC license takes 60 seconds. Go to MyFloridaLicense.com, click “Verify a License,” search by the CAC number or by business name, and confirm the status reads “Current/Active.” The same record shows the license class, the qualifying agent's name, the active dates, and any disciplinary actions on file. Doing this before the in-home assessment, not after the contract is in front of you, is one of the smartest steps homeowners can take toward maximizing HVAC system lifespan and protecting the quality of a major system replacement investment. 

“In our years replacing systems across Clermont, especially the older flex-duct homes near the Chain of Lakes, we've watched homeowners get burned because the contractor on the quote didn't actually hold the right Florida license class for the equipment size. Pulling up the CAC number on MyFloridaLicense.com before signing takes 60 seconds and saves thousands.”

Final Thoughts

If you searched “what licenses should my HVAC contractor have” before calling anyone, you're already doing the right thing. That single question, asked before any contract is signed, prevents more bad outcomes than any other step a Florida homeowner can take on a system replacement.

Clermont is growing fast. New master-planned communities are going up across Lake County, and there's a steady volume of replacement work in the older homes near the Chain of Lakes. Most of the contractors working this market are good. A small number operate without the right license class, without EPA 608 on the truck, and without insurance you could fall back on if something goes sideways. That’s why homeowners looking for a reliable HVAC replacement service should always take a minute to verify who they’re hiring before signing a contract. Sixty seconds on MyFloridaLicense.com tells you which kind you're hiring. We'd rather lose a quote to a neighbor who did the check and choose a different licensed contractor than win one from a neighbor who didn't check at all.
