Local context for Miami
Miami building permits run through the iBuild portal. Miami and all of Miami-Dade County fall inside the High Velocity Hurricane Zone (HVHZ) under the Florida Building Code 8th Edition, which requires Miami-Dade Notice of Acceptance (NOA) approval for windows, doors, roofing, and other envelope products. Ultimate design wind speeds in HVHZ reach 170 mph to 200 mph per ASCE 7-22, the most stringent in the US.

Several local factors push Miami hvac pricing above or below the national baseline:
Why do Miami windows cost so much more than windows in other cities?
Miami-Dade HVHZ requires Miami-Dade Notice of Acceptance for impact windows, which involves large missile impact testing (a 2x4 fired at the glass) plus cyclic pressure testing. The materials, glazing, and framing needed to pass these tests cost substantially more than standard windows.
Do I need a permit for hurricane shutters in Miami?
Yes. Hurricane shutters are a permitted installation in the City of Miami, and the product must carry a Miami-Dade NOA or Florida Product Approval with HVHZ designation. Both permanent and accordion-style shutters require permits and inspections.
City of Miami Building Department handles hvac permits in Miami. Fees, inspection schedules, and code amendments vary by project scope.

Our estimates cover equipment, labor, and permits for typical installations. The biggest accuracy variable is ductwork — if your existing ducts need repair or replacement, add $2,000-$7,000 to the estimate.
Permit requirements in Miami follow Florida state building code plus local amendments. For most homeowners, 17-18 SEER2 offers the best balance of upfront cost and energy savings. In hot climates where AC runs 6+ months, consider 19-20 SEER2 for faster payback on the efficiency premium. See our Florida permit guide for specifics.
In 2026, heat pumps are the better choice for most climates on operating cost alone. They heat AND cool (replacing both furnace and AC) and cost 30–50% less to operate. Note: the $2,000 federal Section 25C tax credit that incentivized heat pumps through 2025 expired December 31, 2025 under the One Big Beautiful Bill Act — systems placed in service in 2026 do not qualify. See our heat pump vs furnace comparison for the full math.
A straightforward equipment swap takes 1-2 days. If new ductwork is needed, expect 3-5 days. Switching system types (e.g., furnace to heat pump) takes 2-4 days.
Yes. HVAC replacement requires a mechanical permit in virtually all jurisdictions. Your contractor should handle this. Expect $150-$400 for the permit fee.
