Warm air from the vents has a short list of causes — and the first two are settings you can check yourself before anyone charges you a service call.
Handle it soon — these get more expensive with time. It's fine to reset a tripped AC breaker once. If it trips again, leave it off and call a pro — a breaker that won't hold is protecting you from a real electrical fault.
Common causes:
• The thermostat fan set to ON instead of AUTO, so the blower circulates room-temperature air between cooling cycles
• A tripped breaker or failed capacitor keeping the outdoor unit dead while the indoor blower keeps pushing air
• A refrigerant leak that has drained the system's ability to actually remove heat
• Leaky return ducts pulling scorching attic air in and mixing it with the cooled supply — a Florida attic can undo a healthy system
• A diagnosis made without ever checking whether the outdoor unit is running
• Refrigerant added by the pound with no leak search — the warm air will be back
• No license number on the truck or invoice for state-licensed air-conditioning work
• A replacement pitch before the cheap causes — settings, breaker, capacitor — have been ruled out
Why does the air feel warm only in the afternoon?
A system that keeps up in the morning but loses ground in afternoon heat is usually fighting a marginal problem — a dirty coil, duct leaks in a hot attic, or a system that was undersized or has lost capacity. It deserves a real inspection, not a guess.
Should the thermostat fan be on AUTO or ON?
AUTO for cooling comfort — the blower stops when the cooling cycle stops, so it never circulates un-cooled air. ON runs the blower continuously, which mixes warm air between cycles and adds humidity in Florida's climate.
AC repair (capacitor / fan / minor): $150–$1,200 (typical ~$400)
A compressor is the expensive failure — often $1,500–3,000+.

Florida licenses this trade at the STATE level (DBPR / CILB (Class A/B)). Hiring unlicensed for this work is illegal for the contractor — and risky for you: no permit rights, no insurance backing, no recourse.
Work like this often requires a county permit — a legitimate pro pulls it, not you.
Basis: FL Stat. 489 (DBPR state licensing).
