FL Permits & Licensing
What Florida requires for HVAC work — permits, licensing, inspections, code compliance, and the A2L refrigerant transition.
Which Jobs Require Permits
| Permit required | No permit needed |
|---|---|
| New system installations (residential + commercial) | Minor repairs (capacitor, contactor, thermostat, fan motor) |
| Full system replacements (indoor and/or outdoor) | Routine maintenance (filter changes, coil cleaning, refrigerant top-off) |
| System upsizes or reconfigurations | Like-for-like component swaps that don't change capacity |
| Ductwork modifications (significant alterations, >50% replacement) | |
| Mini-split installations with new line sets and electrical | |
| Equipment relocation |
Gray area: thresholds vary by county. In Clearwater/Pinellas, repair/replacement under $7,500 may have reduced requirements, but a permit is still needed for system-level work. Always verify with the local building department.
Permit Process (Pinellas County / Clearwater)
Step 1: Determine jurisdiction
City of Clearwater issues permits for properties within city limits — (727) 562-4580, myclearwater.com/epermits. Pinellas County issues permits for unincorporated areas — (727) 464-3888, buildingpermits@pinellas.gov. First step on every job: verify which jurisdiction using the county's address lookup tool.
Step 2: Submit through the Accela portal
Create an account on the Pinellas County Access Portal (available 24/7). Upload: completed application, system specifications (make/model/tonnage/SEER2), AHRI certificate, Manual J load calculations, contractor license and insurance verification.
Step 3: Notice of Commencement
Required for projects over $7,500 (most full system replacements). Must be recorded with the Pinellas County Clerk of Court and uploaded to the permit portal before the first inspection.
Processing times and fees
| Permit type | Review time |
|---|---|
| Express (simple changeouts) | Same day — often immediate after payment |
| Residential trade (HVAC, electrical, plumbing) | 1–5 business days |
| Residential complex | ~14 days |
| Commercial | ~21 days |
| Commercial complex | 2–6 weeks |
Mechanical/HVAC permits: $125–$225 (varies by scope). Fee schedule updated July 1, 2026.
Inspections
Three inspection types: rough-in (before walls/ceilings close), mechanical (equipment installation), and final (full system operation and code compliance). Schedule through the Accela portal by 4 PM for next-business-day inspection.
Pre-inspection checklist
- All connections complete and secure
- Permit card posted at job site
- AHRI certificate available
- Load calculations available
- Equipment leveled, disconnect installed and accessible
- Condensate drain flowing properly with trap
- All ductwork supported and sealed
- Breaker and wire sizes match nameplate
- Hurricane strapping/pad in place (outdoor units)
Top failure reasons
Electrical mismatch (breaker/conductor vs equipment specs), wrong or missing disconnect, condensate trap errors, equipment not level, crushed flex duct, missing documentation, and premature inspection scheduling. The most expensive: never closing permits — an open permit creates problems at property sale or refinance.
Florida Code Requirements
| Requirement | Standard |
|---|---|
| Minimum efficiency (residential) | SEER2 15 (split systems, effective 2023) |
| Load calculations | Manual J mandatory — rule-of-thumb sizing is prohibited by FL Building Code |
| Duct leakage | ≤4 CFM25 per 100 sq ft (new construction); >50% duct replacement triggers full testing |
| Hurricane pads (Clearwater) | Wind speed design zone ~140–150 MPH; 4" height, 3,000 psi concrete, steel reinforced |
| Condensate drains | Proper slope, manufacturer-specified trap, secondary drain or float switch in attics |
| Ventilation | ASHRAE 62.2 (residential), ASHRAE 62.1 (commercial) |
A2L Refrigerant Transition
As of January 1, 2025, all new residential AC/heat pump equipment must use refrigerants with GWP below 700 (AIM Act / EPA 40 CFR Part 84). R-454B replaces R-410A for most split systems. R-32 replaces R-410A primarily for ductless mini-splits (Daikin). Both are classified ASHRAE A2L: low toxicity, mildly flammable.
| Refrigerant | Era | 2026 status |
|---|---|---|
| R-22 | Pre-2010 | Production banned; premium-priced reclaimed only |
| R-410A | ~2010–2024 | Servicing legal; supply gradually phasing down |
| R-454B / R-32 | 2025+ | Required for all new equipment |
Contractor requirements: EPA 608 exams updated in 2025 to include A2L handling. Leak sensors required in some installations. Parts are NOT cross-compatible between R-410A and A2L systems.
Licensing
| License type | Scope | System limits |
|---|---|---|
| Class A (Unlimited) — State Certified | Work anywhere in FL | Any size |
| Class B (Limited) — State Certified | Work anywhere in FL | Cooling <20 tons, heating <500K BTU |
| Registered | Specific local jurisdictions | Varies by local board |
Requirements: 18+, 4+ years verified HVAC experience, trade knowledge exam, business and finance exam, FICO 660+, background check, insurance ($100K public liability + $25K property damage per FL Statute 489.115).
As of July 1, 2023 (HB 735), state-certified contractors are no longer required to register with the Pinellas County Construction Licensing Board.
Duke Energy Rebates
Duke Energy serves Clearwater and offers rebates for qualifying installations:
| Equipment | Rebate | Requirements |
|---|---|---|
| HVAC system (heat pump or AC) | Up to $600 | ENERGY STAR certified, complete replacement, licensed contractor |
| Duct repair | Up to $450 | — |
| Attic insulation (R-38) | $600–$800 | Per sq ft rates |

Hurricane Season & HVAC
Hurricane season: June 1–November 30. Clearwater/Pinellas County is directly on the Gulf coast. Three phases:
Pre-season (May)
Back up all data to cloud, establish employee emergency communication plan, verify outdoor units are secured to hurricane-rated pads (150 MPH for Clearwater), offer "Hurricane HVAC Prep" as a seasonal service package (inspection + surge protector + anchoring verification).
Active storm
Advise customers to shut off AC at thermostat 2–3 hours before dangerous winds. Shut down systems at 45 MPH sustained winds. Secure vehicles. Pre-plan post-storm priority: commercial SLAs first, then elderly/medical, then agreement members, then general.
Post-storm
Expect 3–5× normal call volume for 2–4 weeks after a direct hit. Common issues: refrigerant leaks from line damage, electrical component failures from surge, physical coil damage from debris. Do not restart any system without professional evaluation. Permitting still applies post-storm — unlicensed/unpermitted work is a second-degree misdemeanor and may invalidate the customer's insurance claim.
Business Tax Receipt (BTR)
Separate from your contractor license — a BTR is a tax for operating a business within a municipality. All businesses within Clearwater city limits must obtain one (epermit.myclearwater.com). Businesses outside Clearwater that perform work within city limits must also register. Cost: $25–$175 per jurisdiction. Business tax year: October 1–September 30, renewal begins July 1.
Multi-jurisdiction note: If you work across multiple Pinellas municipalities (Clearwater, St. Petersburg, Largo, etc.), a separate BTR may be required in each. This is a common compliance gap.
