How to Start an HVAC Business in Florida (2026)
Key takeaways
- EPA 608 (federal) is required everywhere, including Florida.
- Florida licenses HVAC at two levels: Certified (valid statewide) and Registered (valid only in the county or city that issued your competency card).
- Both levels run through the DBPR's Construction Industry Licensing Board (CILB) — Florida is strict, and there's no legal unlicensed path for real HVAC work.
- Your FL LLC is filed on Sunbiz; Florida charges an annual report (~$138.75) and requires workers' comp with even one employee in construction.
What do you need to start an HVAC business in Florida?
Four pieces: your federal certification, your Florida license, a registered business, and insurance. The trade you already know — this is everything around it.
| Requirement | Florida specifics |
|---|---|
| EPA 608 certification | Federally required to handle refrigerant. Depending on the type of equipment you're working on, you need either Type I, II, III or Universal. Does not expire. |
| FL HVAC license | DBPR mechanical or air-conditioning contractor — Certified (statewide) or Registered (valid only in the local jurisdiction that issued your competency card). |
| FL LLC | Articles of Organization filed with the Florida Division of Corporations (Sunbiz). |
| EIN | Free from the IRS, same day. |
| Insurance & workers' comp | General liability and property-damage coverage required for licensure; construction workers' comp required with even one employee. |
How do you get an HVAC license in Florida?
Florida's Department of Business & Professional Regulation (DBPR) licenses HVAC through the Construction Industry Licensing Board (CILB), and the state offers two levels. This is the distinction that defines Florida: Certified licenses are issued by the state and work everywhere in Florida, while Registered licenses come from a local competency card and only work in that jurisdiction.
| Certified (statewide) | Registered (local) | |
|---|---|---|
| Valid where | Anywhere in Florida | Only the county/city that issued your competency card |
| License | Certified Mechanical / Air-Conditioning Contractor (CILB) | Registered Mechanical / Air-Conditioning Contractor |
| Experience | ~4 years (experience and/or education combination) | Set by the local jurisdiction |
| Exams | State trade exam + Business & Finance (via Pearson VUE) | Local county competency exam |
| Financials / insurance | Credit report + proof of financial responsibility + general liability & property-damage insurance | Set locally + insurance |
| Typical fees | ~$135 application + exam fees | Local exam + registration fees |
Florida also splits air-conditioning work into classes (a Class A contractor has no capacity limit; a Class B is capped at smaller systems), and mechanical contractors cover the broader range of heating, cooling, and refrigeration. Whichever route you take, the Business & Finance exam and proof of financial responsibility apply. You verify any Florida license through the DBPR's online license lookup.
Registering your HVAC business in Florida
Once your license path is set, forming the business itself is straightforward:
- Choose and check your business name against the Florida Division of Corporations (Sunbiz) records.
- The Articles of Organization — filed with the Florida Division of Corporations (Sunbiz), online.
- Your registered agent (you can be your own for free, or use a service).
- Your federal tax ID (EIN) — free from the IRS — same day.
- Open a business bank account and set up bookkeeping.
- Check for a local business tax receipt — most Florida counties and cities require one.
Florida requires an annual report every year (about $138.75, due by May 1) to keep your LLC active, and the construction industry must carry workers' compensation once you have even one employee — a stricter threshold than most states.

Getting your first HVAC customers in Florida
Once you're licensed and set up, your first jobs come from being findable locally — not from a big ad budget. Set up a Google Business Profile for your service area — South Florida (Miami–Fort Lauderdale), Tampa Bay, Orlando, or Jacksonville — ask every happy customer for an honest review, build relationships with local supply houses, and take on overflow or subcontract work from established Florida HVAC companies to start. In Florida's year-round heat and humidity, cooling never stops working — seasonal and annual maintenance agreements are the best way to build steady, recurring revenue.
Before you file: Florida licensing rules, exam requirements, and fees can change, the Certified-vs-Registered distinction matters, and local business-tax rules vary by county and city. Always confirm the current requirements directly with the Florida DBPR / Construction Industry Licensing Board (myfloridalicense.com) and your local jurisdiction before you rely on any figure here.

What license do you need for an HVAC business in Florida?
Federal EPA 608, plus a Florida mechanical or air-conditioning contractor license through the DBPR's CILB. Florida is strict and licenses at two levels: Certified (valid statewide) and Registered (valid only in the local jurisdiction that issued your competency card). Confirm current thresholds with the Florida DBPR.
What's involved in registering a business in Florida?
The Articles of Organization go to the Florida Division of Corporations (Sunbiz), a registered agent is named (that can be you), and the IRS issues the EIN free. You remain the applicant on every filing. Florida requires an annual report every year (about $138.75, due May 1), and construction businesses must carry workers' comp with even one employee.
What is the difference between a Certified and a Registered HVAC license in Florida?
A Certified license is issued by the state and lets you work anywhere in Florida. A Registered license comes from a local competency card and only lets you work in that county or city. Most contractors who want statewide reach pursue the Certified license.
How long does it take to start an HVAC business in Florida?
Once you hold EPA 608 and your Florida DBPR license, doing the setup yourself takes weeks or months, or about a week done for you when everything is run in parallel. Earning the license is the longer variable and depends on your experience, financials, and exam scheduling.
