Yes. In Florida, hvac replacement or installation generally requires a permit, and Miami is no exception.

Only portable or window units and minor in-cabinet repairs avoid a permit. Changing amperage or fuel type adds electrical or gas review.
Local and county notes for Miami
The HB 803 $7,500 exemption does not cover mechanical work. Upsizing amperage or changing fuel type adds electrical or gas permits. An air conditioning change-out is a permit category in the City of Miami; only mechanical repairs under $2,500 performed by a licensed contractor, and minor part or duct repairs, are exempt. A/C change-outs qualify for the City of Miami Easy Permit program, which issues the permit by email to a licensed contractor in good standing without plan review, so a homeowner generally cannot self-pull it. Because the entire city is in the High Velocity Hurricane Zone, replacement equipment must be anchored to HVHZ standards and may require a Miami-Dade NOA or Florida Product Approval. Outdoor equipment must be anchored to resist HVHZ wind loads, and stands or elevated platforms are commonly required. Your city issues the permit, not the county. Miami-Dade County's own building department serves the unincorporated area, while each municipality runs its own building department, and the county Board of Rules and Appeals interprets the code across all of them.
