A new HVAC system in Florida costs between $6,400 and $13,000 in 2026, with the average homeowner paying about $8,600 for a complete system replacement. That's about 4% above the national average — reasonable considering Florida's AC runs 8–10 months per year, and the state's building code has specific hurricane and humidity requirements that other states don't face.
Florida is America's third-largest HVAC market and arguably the most AC-dependent state in the country. Your AC isn't a luxury here — it's survival equipment. This guide covers every cost detail, from Miami to Jacksonville, so you know exactly what to expect.
Florida HVAC Costs at a Glance
Florida-specific note: Most Florida homes use heat pumps or AC with electric air handlers rather than gas furnaces. Natural gas availability is limited in many Florida communities. If your home uses an AC + electric heat strip setup (common in Florida), your "furnace" replacement is actually an air handler replacement, which is less expensive.
Why Florida HVAC Costs Are What They Are
Florida's HVAC market has unique characteristics that shape pricing:
AC-Dominant Market
Florida homes use air conditioning more than almost any other state. Your AC compressor runs an estimated 2,800–3,500 hours per year in South Florida and 2,200–2,800 hours in North Florida — compared to 1,000–1,500 hours in northern states. This extreme usage means systems wear out faster (10–14 year average life) and replacements are frequent, which keeps the contractor market competitive.
Florida Building Code (FBC) Requirements
Florida's building code includes requirements other states don't have:
- Hurricane/wind resistance: Outdoor equipment must be secured to withstand high winds. Concrete pads, hurricane straps, and elevated installations in flood-prone areas add $200–$800.
- Energy code compliance: Florida follows the IECC with state amendments. Load calculations and equipment efficiency minimums apply to all permitted work.
- Permits required statewide: Unlike Texas, Florida requires mechanical permits for HVAC replacement in every jurisdiction. Permit costs range from $150 to $500.
Humidity Factor
Florida's extreme humidity (averaging 70–80% in summer) creates specific equipment needs. Standard single-stage AC systems often struggle with humidity control, making two-stage and variable-speed systems especially valuable here. These higher-tier systems cost more but deliver dramatically better comfort.
Salt Air Corrosion
Homes within 10 miles of Florida's coastline face accelerated equipment corrosion from salt-laden air. Coastal installations should use equipment with coastal corrosion protection (coated coils, stainless steel hardware), which adds $300–$800 to equipment cost but extends system life by 3–5 years.
HVAC Costs by Florida Region
South Florida (Miami-Dade, Broward, Palm Beach)
Climate: Tropical. Hot and humid year-round. AC runs nearly 365 days. Minimal heating needs.
Typical system: 3–5 ton AC or heat pump + air handler. Gas furnaces are uncommon.
Average full system cost: $9,200–$14,000
South Florida is the most expensive Florida region for HVAC. Higher labor rates in the Miami metro, strict Miami-Dade County building code requirements, and the need for coastal-rated equipment all push costs up. Miami-Dade has the most stringent product approval requirements in the state — equipment must have Miami-Dade product approval (NOA, Notice of Acceptance).
Example: Coral Springs, FL (Broward County) — 2,000 sq ft home. Replacing a 12-year-old 3.5-ton AC + air handler with a Carrier 17 SEER2 AC + variable-speed air handler with 10kW heat strips. Equipment: $5,400. Labor: $2,800. Hurricane pad and strapping: $350. Materials: $650. Permits: $400. Total: $9,600.
Tampa Bay Area
Climate: Subtropical. Hot, humid summers. Mild winters with occasional cold fronts into the 30s–40s°F.
Typical system: 3–4 ton AC or heat pump + air handler
Average full system cost: $8,200–$12,500
Tampa Bay offers more moderate pricing than South Florida. A healthy contractor market and slightly lower labor rates help. The region's humidity demands quality equipment — variable-speed or two-stage systems are strongly recommended here.
Example: Clearwater, FL — 1,800 sq ft home. Installing a 3-ton Trane 16 SEER2 heat pump + air handler, replacing an aging AC + electric heat system. Equipment: $5,200. Labor: $2,400. Materials: $550. Permits: $300. Total: $8,450. After federal tax credit ($2,000): Net: $6,450.
Orlando / Central Florida
Climate: Subtropical. Very hot, humid summers. Cool winters with occasional freezes.
Typical system: 3–4 ton AC or heat pump + air handler or gas furnace (gas more common here than South FL)
Average full system cost: $8,000–$12,000
Central Florida benefits from competitive pricing and access to contractors from both Tampa and South Florida markets. The rapidly growing population (especially in the I-4 corridor) keeps HVAC demand high but also attracts new contractors.
Example: Kissimmee, FL — 2,200 sq ft home. Replacing a 4-ton Rheem system with a new Rheem 16 SEER2 AC + 80,000 BTU gas furnace (natural gas available). Equipment: $4,800. Labor: $2,600. Materials: $600. Permits: $350. Total: $8,350.
Jacksonville / North Florida
Climate: Subtropical, but with colder winters than the rest of Florida. Freezes are common December through February.
Typical system: 3–4 ton AC or heat pump + gas furnace or air handler with heat strips
Average full system cost: $7,800–$11,800
North Florida is the most affordable region in the state. Labor rates are lower, and the climate is slightly less demanding on AC systems. However, heating matters more here — you'll want reliable heating capacity, whether from a gas furnace, heat pump, or electric heat strips.
Example: Jacksonville, FL — 1,600 sq ft home. Replacing a 3-ton system with a Goodman 16 SEER2 heat pump + air handler. Equipment: $4,400. Labor: $2,200. Materials: $500. Permits: $250. Total: $7,350. After federal tax credit ($2,000): Net: $5,350.
Southwest Florida (Fort Myers, Naples, Sarasota)
Climate: Tropical to subtropical. Very hot and humid. Near year-round AC usage.
Typical system: 3–5 ton AC or heat pump + air handler. Coastal corrosion protection recommended.
Average full system cost: $8,800–$13,500
Southwest Florida pricing is elevated due to coastal corrosion concerns and an affluent market that demands premium equipment. The post-Hurricane Ian rebuilding activity in 2022–2023 also strained the local contractor workforce, and pricing has remained elevated.
Example: Cape Coral, FL — 2,400 sq ft home. Replacing a hurricane-damaged 4-ton system with a Lennox 18 SEER2 AC + variable-speed air handler with coastal corrosion package. Equipment: $6,800. Labor: $3,200. Hurricane strapping and elevated pad: $600. Materials: $750. Permits: $400. Total: $11,750.
Florida Equipment Considerations
Heat Pump vs. AC + Heat Strips: The Florida Decision
In Florida's mild winter climate, the debate between a heat pump and an AC + electric heat strips setup comes down to efficiency and cost:
*Based on a 2,000 sq ft home at Florida electricity rates (~15.8¢/kWh).
For most Florida homeowners, a heat pump is the smarter choice. The upfront cost premium is modest ($1,000–$2,000), it's offset by the federal tax credit ($2,000), and you'll save $150–$300/year on heating costs. The only exception is deep South Florida (Miami-Dade, Monroe County) where heating needs are so minimal that the savings don't add up.
Humidity Control: Why Variable-Speed Matters in Florida
Florida's #1 comfort complaint isn't temperature — it's humidity. A standard single-stage AC cycles on and off frequently, which doesn't run long enough to dehumidify effectively. Here's how different system types handle Florida humidity:
Coastal Corrosion Protection
If you live within 10 miles of any Florida coast (which includes the majority of the state's population), you should invest in corrosion protection:
Standard outdoor unit life near coast: 8–10 years (vs. 12–15 inland)
With coastal protection package: 11–14 years near coast
What "coastal protection" includes: Coated condenser coils (BlueShield, Micro Channel, or similar), stainless steel screws and hardware, coated cabinet and base pan, and weather-resistant electrical connections. Most major brands offer factory-installed coastal packages for $300–$800 extra.
Florida HVAC Rebates and Incentives for 2026
Federal Incentives (Available Statewide)
- 25C Tax Credit: Up to $2,000 for qualifying heat pumps; up to $600 for AC or furnace
- HEEHRA Rebates: Up to $8,000 for heat pumps (income-qualified households)
Florida Utility Rebates
FPL customers (who represent about half of Florida) can also take advantage of FPL's On Call program, which provides free AC maintenance and repairs for a monthly fee. While not a direct installation rebate, it can save significant money on ongoing maintenance after your new system is installed.
Florida-Specific Programs
Florida PACE (Property Assessed Clean Energy): PACE financing allows you to finance HVAC improvements through a property tax assessment. No upfront cost, and payments spread over 10–20 years. Available in most Florida counties. Interest rates are typically 6–9%.
Solar + HVAC Combo: Many Florida solar installers offer discounted HVAC installation when bundled with a solar panel installation. This can save $1,000–$3,000 on the HVAC portion.
PACE financing caution: While PACE makes new HVAC accessible with zero upfront cost, the total cost over the loan term is significantly higher than paying cash or using a traditional loan. PACE assessments also become a lien on your property, which can complicate selling your home. Read all terms carefully before signing.
Florida Permit Process: What to Expect
Florida requires mechanical permits for all HVAC installations statewide. Here's how the process works:
Step 1: Contractor pulls permit. Your HVAC contractor should handle this. Permit fees range from $150 to $500 depending on county.
Step 2: Installation. Standard installations take 1–2 days.
Step 3: Inspection. A county building inspector visits to verify the installation meets Florida Building Code. Typical wait time: 3–7 business days after installation.
Step 4: Final approval. The inspector signs off, and the permit is closed. You should receive a copy of the closed permit for your records.
Seasonal Pricing in Florida
Florida's HVAC market has a somewhat different seasonal pattern than northern states:
Peak season (April–September): AC demand skyrockets. Emergency replacements during summer heat command 15–20% premiums. Wait times: 1–3 weeks for non-emergency installs.
Hurricane season overlay (June–November): After major storms, HVAC contractors are booked for weeks or months with damage restoration and replacement. Post-hurricane pricing can spike 20–40%.
Off-season (November–February): Best pricing window. Contractor demand drops, and many offer 10–15% seasonal discounts. Wait times: 3–7 days.
Shoulder season (March, October): Moderate pricing and availability. A good time to get quotes.
Florida pro tip: Schedule your replacement for December or January. Contractors are slowest, prices are lowest, and you'll have a brand-new, efficient system ready for the spring/summer heat. Don't wait until your AC dies in July — that's the most expensive, most stressful way to replace your system.
Finding a Licensed Florida HVAC Contractor
Florida requires HVAC contractors to hold a state license issued by the Construction Industry Licensing Board (CILB) through the Department of Business and Professional Regulation (DBPR).
License types: Florida issues two classes — Certified (statewide) and Registered (county-specific). Certified contractors can work anywhere in the state. Registered contractors are limited to the county where they're registered.
Verify online. Visit myfloridalicense.com to search for any contractor. Look up their license type, status, and any complaints.
Insurance. Florida requires licensed contractors to carry general liability insurance and workers' compensation. Ask for certificates of insurance.
Specific to look for:
- CAC (Class A Air Conditioning Contractor) license for unlimited HVAC work
- CMC (Class B Mechanical Contractor) license also covers HVAC
- Verify the license is active and in good standing
