HVAC Replacement Cost in Florida (2026)

HVAC replacement in Florida typically runs $8,200–$19,800 for a complete 3-ton system replacement, with electric heat pumps as the dominant heating choice and roughly 600 heating degree days against 4,100 cooling degree days driving the seasonal load mix. Year-round cooling-dominant load with dewpoints above 75°F daily May through October pushes latent dehumidification capacity ahead of sensible — heat pumps with variable-speed inverter compressors and ECM blowers are the dominant equipment, and HVHZ wind-load brackets anchor every condenser pad in Miami-Dade and Broward.

Florida climate & load drivers

  • IECC climate zone: 1A-2A
  • Annual load split: Cooling-dominant — annual cooling load exceeds heating load (600 HDD / 4,100 CDD)
  • Dominant heating fuel: Electricity (heat pump) — air-source HPs as primary heat
  • Dominant cooling system: Air-source heat pump providing both heating and cooling

Florida licensing & permits

  • License status: Statewide license required
  • License board: Florida CILB — Class A Mechanical Contractor (unlimited) / Class B (≤25-ton, ≤500k BTU) per F.S. 489 (official site)
  • Permit: permit required statewide; HVHZ counties require NOA on equipment

How HVAC replacement costs vary in Florida

State-specific code or insurance rule: Florida Energy Conservation Code Section R403 mandates a minimum duct R-6 plus pressure-tested duct leakage of 4 cfm per 100 sq ft of conditioned floor area on every change-out, and Miami-Dade and Broward HVHZ jurisdictions require a Notice of Acceptance (NOA) on every air handler and condenser installed.
